Linux File System Comparison: XFS vs. 여러 가지의 HDD를 장착하여 사용을 하신다면 사진이나 중요한 자료들을 저장하는 드라이브에는. だが、Linux 5. For single disks over 4T, I would consider xfs over zfs or ext4. Use whatever your distro vendor supports: on Redhat and spinoffs, use XFS+LVM (the latter gives you snapshotting capabilities today;: XFS itself will receive them in the medium term), on Suse use BTRFS. Conclusion: Last time I ran these tests, xfs and ext4 pulled very similar results, and both were miles ahead of btrfs. Next lets modify our fstab to match something like this ( remember to change the file-system from ext4 to btrfs in the next column) nano /etc/fstab. See FUSE. Rationale is native Linux nature, vs xfs being Linux supported. This article provides a detailed comparison of XFS vs btrfs to help you determine which file system is a better fit for your use case. The first command looks like this: dd if=/dev/zero of=file-sparse bs=1 count=0 seek=2G. Moreover, the ext4 is more beneficial when the. "EXT4 does not support concurrent writes, XFS does" (But) EXT4 is more "mainline"Btrfs is licensed under the GPL and is open source. XFS doesn't have any RAID, while Btrfs RAID is not yet completely stable and is in its early days. It was also 164% faster in post-snapshot reads and 17% faster in post-snapshot writes. The 3TB HDD are ext4. Si su aplicación falla con números de inodo grandes, monte el sistema de archivos XFS con la opción -o inode32 para imponer números de inodo inferiores a 232. Precisely, it seems to be 50%. It has features that can scale better than ext4 and is even preferred over ZFS by some users. The inode system creates a separate table on each. X percent… The more modern filesystems of BTRFS and ZFS not only have data integrity features but also the inline compression pushes the efficiency past 100% in many cases. 但无论如何，各个文件系统都需要存储这三类信息，因为这是内核规定的（见下）。. Tbh, it depends on game by game basis Team Fortress 2 will go as low as nearly 50%, same for KSP. You either copy everything twice or not. What takes up space is each consecutive data change, that is why snapshots are created instantaneously. Both timeshift and borg write to it. I've used EX4, XFS, EXT4+LVM and now I'm under BTRFS, and I can tell you, TF2, CSGO, Factorio, KSP, etc, all perform the same under all of them. Considering switching from a mixture of XFS and ext4, but only to Tux3 once that's merged. After much reading on ReFS, Btrfs, & ZFS, I've decided to run all 3 🤷♂️(Did the same with Seagate vs. ZFS is an advanced filesystem and many of its features focus mainly on reliability. Ceph's recommendation for the choice of filesystem is between btrfs and XFS. Uma das decisões que você tem que tomar quando vai instalar qualquer distro Linux é o Sistema de arquivos do Linux! São vários para escolher, EXT4, XFS e BTR. Though not as large of a difference when comparing to an SD card. 0 NVMe SSD was used for the benchmarking of these file-systems in different desktop use-cases. So với Ext4, Btrfs hoạt động ổn đinh hơn, dễ dàng quản lý hơn và tích hợp nhiều ứng dụng hỗ trợ tốt cho doanh nghiệp Quy mô lớn. That bug apart, any delayed allocation filesystem (ext4 and btrfs included) will lose a significant number or un-synched data in case of uncontrolled poweroff. EXT4 had the best speed at 58MB/s while Btrfs came in slightly behind that at 52MB/s and then ZFS came in at 46MB/s. To be clear, I am using RAID0 with two SSDs with strip size of 256Kb. at least thin-LVM as storage type is something that. Otherwise use BTRFS. Ability to create large volumes of up to 1 PB 1. Btrfs would be adding features you most likely don't need. However, BTRFS had significantly better performance with small files than EXT4. The btrfs backup multi-disk arrangement, of different disk sizes in single mode was for me a trial of btrfs. Bcachefs is the file-system born out of the Linux kernel's block cache code and has been worked on the past several years by. The XFS File System. My recommendation of that list would be XFS. Comparison of archive formats. Linux 5. Die Benchmark-Testergebnisse zeigten, dass BTRFS etwas niedrigere Lese- und Schreibgeschwindigkeiten als EXT4 hatte. Although both ext4 and XFS are excellent at what they do, neither are suited to some of today’s more complex storage challenges. The check task is involves reading roughly 2000 small files in their entirety and performing some processor intensive tasks on them. However, Ext3 lacks advanced file system features like extent blocking mapping, dynamic allocation inode, and defragmentation. My biggest issue with any file system other than EXT4 is that a lot of linux programs are built and tested on EXT4. Usable space isn't a big issue but I don't want to lose half with RAID 10. Data integrity protection. EXT4 vs. 15 or newer (Please the same OS using same activating services and same apps!)The snapshots do not take up any space. BTRFS vs EXT4 speed and compression. 38. The problem (which i understand is fairly common) is that performance of a single NVMe drive on zfs vs ext4 is atrocious. For a future article will be a look at non-mainlined file-systems, including ZFS On Linux. I'ved tested compress=off/lz4, dedup=on/off and serveral Cache/Log constellations on 256GB SSD. For BTRFS, the overall throughput is fairly low (~30k tps), while the jitter is somewhat better and worse than for EXT4/XFS at the same time. You might also want to consider Btrfs for your array drives, but you should be aware of the potential risks. ZFS certainly can provide higher levels of growth and resiliency vs ext4/xfs. 하지만 리소스 문제나 호환성 등을 생각한다면 EXT4도 포기할 수 없죠. Because ext4 is deficient as an enterprise level fs, Red Hat has spent quite a. Edit: I managed to save the two NTFS HDDs with chkdsk, but the exFAT drive just didn't wanna play ball. The ext FilesystemsHere is a look at the Linux 5. In this test, Btrfs outperformed LVM in every benchmark. 356 Btrfs—short for "B-Tree File System" and frequently pronounced "butter" or "butter eff ess"—is the most advanced filesystem present in the mainline Linux kernel. One of the biggest differences between them is that their supported operating system. Ext4 and XFS are the fastest, as expected. This is an issue for those like me who have older laptops e. Both. The ext4 file system records information about when a file was last accessed and there is a cost associated with recording it. XFS vs. In the case of the Intel 900p SSD, the XFS results were too fast to accurately measure while EXT4 and F2FS took just two seconds to complete while Btrfs took six seconds. BtrFS refers to B-Tree File Systems developed by Oracle to establish an alternative to the Ext series. Supported LBA Sizes (NSID 0x1) Id Fmt Data Metadt Rel_Perf 0 - 512 0 2 1. But. 另外，我们常说的file对象，它用于关联进程和dentry对象的. Btrfs Btrfs support has been included with the mainline 2. . XFS is better larger files and long-term maintaince and stability. #11. Both ext4 and XFS should be able to handle it. BTRFS and ZFS are metadata vs. It's the fastest option bar none if you have enough RAM. ZFS is open source, it isn't "owned" by Oracle. With the comparison table out of the way, let’s get right into it! Ext4 Overview. Small to Medium Enterprises: While ext3 suffices for businesses with modest data needs, scalability visionaries would do well considering ext4. Você pode então configurar a aplicação de cotas usando uma opção de montagem. XFS A number of Phoronix readers have been asking about some fresh file-system comparisons on recent kernels. BtrFS looked promising, but last I checked it still couldn't be trusted in RAID modes. Is XFS better than btrfs? September 30, 2023 by Garry. WD & Windows vs. 8. Here, you can use either command: dd, or truncate. Then again maybe ZFS is the best to use. Ext4 seems better suited for lower-spec configurations although it will work just fine on faster ones as well, and performance-wise still better than btrfs in most cases. XFS as a similar featureset filesystem manages around 99. Each of the tested file-systems were carried out with the default mount options in an out-of-the-box manner. Another way to characterize this is that the Ext4 file system variants tend to perform better on systems that have limited I/O capability. I’d have to say that depends a lot on your perspective as to ‘age’. As far as I know, the 4k block size is important for such webgui, it makes it faster to open sites (for ex. To mount the XFS file system so that it uses the external journal, specify the -o logdev=device option to the. After conversion I: enabled compression. Ext4 has been around for a while and is generally more reliable and backward compatible. g. 3. Having this opportunity I wanted to put some hard numbers to my previous observations regarding ext4 vs Btrfs performance on my T430 running Qubes OS R4. ZFS likes eating RAM. ) TL, DR: All 3 major next gen CoW file systems have their advantages and drawbacks, and I figure integrating them into my workflow is the only way to fairly evaluate them see how they work for myself. F2FS vs. But yeah, it's (BTRFS) a more complex filesystem with a bottomless pit of asterisks and gotchas attached to it, EXT4 is much more limited in scope and much simpler from a design perspective. Btrfs es mucho más rápido de lo que crees basándote en esos benchmarks, ya que no se ajustan a tu caso de uso. XFS is optimized for large file transfers and parallel I/O operations, while ext4 is optimized for general-purpose use with a focus on security. So, Btrfs has built-in RAID support and therefore this feature is inherent in it. For example btrfs supports transparent file compression. XFS supports larger file sizes and. 356 Btrfs—short for "B-Tree File System" and frequently pronounced "butter" or "butter eff ess"—is the most advanced filesystem present in the mainline Linux kernel. Find out which file system suits your needs best. Thanks! In that case, your choice is simple. EXT2/3/4: Extended Filesystem is by far the most popular filesystem among Linux desktop installations. However, I was using the openSUSE's default partition layout, which is btrfs for / and xfs for /home. EXT4. 1. In a few words, I just need a really reliable and fast filesystem for years ahead, with the care of SSD in mind, I need it mostly for gaming, video-audio production, working with a lot of small/medium files (from 100-500Kb to 100-150Gb) sending them. The only realistic benchmark is the one done on a real application in real conditions. I have a raid 1 setup on dual 3. btrfs is also slower in some benchmarks but I very much doubt thats visible in normal use. F2FS vs. Never use ReiserFS on a new system and if you are currently using it, consider converting it to XFS or Btrfs. A execução do comando quotacheck em um sistema de. 2. Yeah reflink support only became a thing as of v10 prior to that there was no linux repo support. 6. We see that on the SMR disk btrfs has most of the advantage on overall ops that it has on ext4, but penalty on random appends is not as dramatic as a ratio. Never use ReiserFS on a new system and if you are currently using it, consider converting it to XFS or Btrfs. Da Btrfs sehr leistungshungriger ist, benötigen NAS-Systeme dafür einen starken Prozessor und ausreichend Arbeitsspeicher. 0-040700-generic (x86_64) Unity 7. Ext4 file system is the successor to Ext3, and the mainstream file system under Linux. The space savings with zstd compression are insane, and I see virtually no performance degradation. Tl;dr: The best filesystem for Unraid. What we mean is that we need something like resize2fs (ext4) for enlarge or shrunk on the fly, and not required to use another filesystem to store the dump for the resizing. This is because BTRFS is optimized for handling small files, while EXT4 can struggle with multiple small files due to its delayed allocation. F2FS vs. I have hard reset my machines running XFS and not once did I have any problems or need to give the partition the "spank of life" if you will. Compared to Ext4, XFS has a relatively poor performance for single threaded, metadata-intensive workloads. 2. 2. Looking at benchmarks however it seems to have poor. ext4,xfs,btrfs,zfsでベンチマークしてます。. 7 - EXT4 vs. BTRFS solves all the problems I had so far: supports online resizing - both extending and shrinking. Btrfs supports RAID 0, 1, 10, 5, and 6, while ZFS supports various RAID-Z levels (RAID-Z, RAID-Z2, and RAID-Z3). Es un sistema de archivos actualizado y también fiable. BTRFS have some fancy features, and could help you manage your disk better in some automation-future-proof way. Btrfs vs ext4 . Very much depends if you want to go JBOD style or have a RAID-type-style though. Comparison of file archivers. 和 ext4 和 XFS 一起使用的工具比较 法律通告 Settings Close. /boot/efi has to be FAT32 (assuming you are using it as the ESP and not just adding partitions extra partitions under /boot to test how robust the boot sequence is). Btrfs is a more modern file system, introduced in 2007. 2. 8ではPhoronixのテストの結果ではXFSが非常に速く、Ext4が遅い。Una vez que hemos conocido las principales características de EXT4, vamos a hablar sobre Btrfs, el que se conoce como sucesor natural del sistema de archivos EXT4. The only time there were issues was when my RAM sticks went bad and btrfs detected it and put my FS into read-only mode to prevent corruption. NTFS Benchmarks Continuing on from yesterday's Linux 4. 3 XFS. The NTFS support was powered by FUSE. ZFS combines a filesystem and volume manager. F2FS, XFS, ext4, zfs, btrfs, ntfs, etc. #filesystem #ext4 #xfs #linuxExplicación de las diferencias entre sistemas de archivos, en este vídeo se comparan los 2 mas usados en GNU/Linux. ext4 and xfs are probably the best fs' to lay over a single disk (and even on raid device if you're familiar with mdraid). creating volumes and mounting them would need to check that option and decide on appropriate mount points. g. Although XFS is older than the latest version of the Ext series, there have been notable differences. The only concern I have is performance, maybe btrfs in a HDD will be really slow. So…. It's a 64-bit, journaling filesystem that has been built into the Linux. The reason that Ext4 is often recommended is that it is the most used and trusted filesystem out there on Linux today. The XFS supports more file sizes and greater file or partition sizes. File-systems tested on the NVMe SSD included Btrfs, EXT4, F2FS, XFS, and NTFS. ext4 is an "advanced" version of ext3 with various improvements, basically an upgrade to the ext3 format. 1. Granted, i just use the automatic partition creater at setup, so it still uses ext4 for the /boot and /boot/efi partitions. 3TB HDD formatted as NTFS for main files. He Installed Linux and partitioned his partition in Ext4 but Hardly after a month he screwed. This is what I ended up doing; BTRFS for operating system partition and ext4 for games. Btrfs, EXT4, F2FS, and XFS were tested in their out-of-the-box state / default mount options. これらのファイルシステムはEXT4、Btrfs、ZFSであり、XNUMXつのファイルシステムは異なる特性を持ち、いくつかは異なるシナリオでより優れたパフォーマンスを発揮します。 外部4. The fourth generation File System of the Ext (Extended) file system family. With the noatime option, the access timestamps on the filesystem are not updated. In a significant data corruption, Ext2 and Ext3 file systems are more possible and easy to recover data due to their data redundancy compared with Ext4. XFS and ext4 are probably where I'd look for a single disk hard drive. On the NVMe SSD, the four-thread FS-Mark was the fastest on XFS followed by Btrfs. But they come with the smallest set of features compared to newer filesystems. Example: Dropbox is hard-coded to use ext4, so will refuse to work on ZFS and BTRFS. misleading. . 1. While options like XFS and ZFS aren’t nearly as famous, there are certain cases where you should consider making them the file system of choice. Btrfs trails the other options for a database in terms of latency and throughput. BTRFS has a number of issues with optimizations (mostly minor) and Problems with Scrubbing and Raid56. use ZFS only w/ ECC RAM. Offizieller Beitrag. 0 unterstützt. The XFS filesystem is the default filesystem in RHEL, CentOS, and other RHEL-distros such as Oracle Linux, Rocky Linux, and AlmaLinux. Puedes crear hasta 264 archivos en un sistema Btrfs. Con: rumor has it that it is slower than ext3, the fsync dataloss soap. It supports large file systems and provides excellent scalability and reliability. If fs performance is the only or most important thing for you, then use xfs - it's the clear winner, by far. We currently recommend XFS for production deployments. Just so perfect to roll back for some games and modding. 0 File-System Benchmarks: Btrfs vs. If you do hardware RAID, with a dedicated RAID card, just do not use ZFS please, it will break your data at some point. Ability to create large volumes of up to 1 PB 1. The question is XFS vs EXT4. Seriously, fuck them. Some feel that it is not mature enough for production use while there are also early adopters of this. Backups and CoW, are why I use btrfs. That is according to my quick read of various Phoronix tests. If you wish to run ext4, xfs or btrfs then you need to run a linux OS not BSD. No ext4, você pode ativar cotas ao criar o sistema de arquivo ou mais tarde em um sistema de arquivo existente. On the other hand, for Linux/Unix-based devices, it might be a bit of a challenge choosing one among many options. The PostgreSQL database server ran well particularly on EXT4 and XFS while F2FS on the USB 3. In practice, I don't consider the Btrfs slowdown really relevant for desktop usage on an SSD, VM performance aside. I heard BRTFS filesystem with continuous trim and unit allocation size of 64kb are the best configs so far. ago. Diferenças básicas entre o Ext4 e o Btrfs. 0 mainline kernel and using the stock mount options. XFS. Both file systems can recover from a power loss, but using Btrfs will not immunize you from them. Ext4 tiene el registro en diario de forma predeterminada y es probable que los nuevos usuarios no sepan cómo deshabilitarlo para guardar lecturas / escrituras en sus. Between 2T and 4T on a single disk, any of these would probably have similar performance. If you omit the size parameter, a journal size based on the size of the file system is used. . Which is better largely depends on opinion. The logical path from Ext4 is to Btrfs. But. Or btrfs, which is making some serious headway again with it becoming the default filesystem for Fedora. Things like snapshots, copy-on-write, checksums and more. freebird54 September 21, 2021, 2:58pm 10. ZFS (defaults): natty: 171. F2FS vs. 1. has built-in support for snapshots - useful for both backups and “testing out” scripts. - Hạn mức (quota) cho các thư mục chia sẻ - Nhân bản toàn bộ Share. This can take anywhere from 10 minutes to even hours, depending on the partition size and whether you have a rotational or solid-state hard drive. This might lead one to move to btrfs on the SMR disk. So I did two rounds: the. Hello guy's "EXT4 vs BTRFS" -that's the question *Let me guess what will happen, you guys will jump in and comment technical replies* But that's not the case here Imagine: There is someone that he/she does not have that much knowledge about Linux. Ext4 was designed with spinning drives in mind but as SSDs are fundamentally different, an SSD optimized file system can help. EXT4 is better for small files and day to day use. i use the nas to store backups (the tools created a bunch of symbolic links) (not from synology) and run a few dockers (a. Copy. You didn't provide the Linux distribution information, but assuming CentOS or Red Hat, XFS is now somewhat integrated. There’s very little difference between EXT4 and XFS, both in total throughput and behavior over time. 7 - EXT4 vs. It. Data integrity protection. 3. Die Benchmark-Testergebnisse zeigten, dass BTRFS etwas niedrigere Lese- und Schreibgeschwindigkeiten als EXT4 hatte. However we have a new contender - ZFS performed *extremely* well on the. file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4,Sure, BtrFS has its benefits and novel features, but "has never once failed me in 10+ years" is an incredibly strong reliability trend that I'd be hesitant to trade for those, especially in a piece of my infrastructure where a single failure could potentially cause massive loss of data and subsequent time spent recovering from backups/etc. windows and linux use one big D: for data storage, NTFS C: and EXT4 Linux are only for OS and software. A number of Phoronix readers have been asking about some fresh file-system comparisons on recent kernels. Ext4 and XFS are the fastest, as expected. My current setup is /@ for the rootfs, /@home for home dir, works great. I've used EX4, XFS, EXT4+LVM and now I'm under BTRFS, and I can tell you, TF2, CSGO, Factorio, KSP, etc, all perform the same under all of them. A tool for managing BTRFS and LVM snapshots. ago. Now Fedora just needs to implement it properly like openSUSE. ran defragment utility to compress all existing files. This file system enables drive pooling, automatic snapshot, transparent compression, and online defragmentation. XFS is more and more mature than Btrfs, but. I've also ran some experiments on some older machines with slow IDE drives, once while installing a distro with ext4, and once with btrfs+zstd as root. XFS is Red Hat’s enterprise filesystem (until they finally trust btrfs). Linux có nhiều tùy chọn hệ thống file khác nhau. EXT4 and XFS show similarities in some features. XFS vs EXT4!This is a very common question when it comes to Linux filesystems and if you’re looking for the difference between XFS and EXT4, here is a quick summary:. - chống phân mảnh dữ liệu nhanh chóng. Data Colossi & Data Centers: Ext4 is non-negotiable for handling extensive data transactions. XFSI've drank the kool-aid and I both run btrfs on root, /home, and for a 1 TB data drive. I've done it by creating both a btrfs & xfs volume that doesn't appear to have any issues, currently using the btrfs one. g. File systems based on copy-on-write (also known as write-anywhere), such as Reiser4, Btrfs and ZFS, have no need to use traditional journal to protect metadata, because they are never updated in-place. wbeater • 3 yr. This correlates with the previous experiment and the hypothesis. Watching LearnLinuxTV's Proxmox course, he mentions that ZFS offers more features and better performance as the host OS filesystem, but also uses a lot of RAM. Btrfs, EXT4, F2FS, and XFS were tested in their out-of-the-box state / default mount options. 88. for the home lab you can use ext4 it is fast an flexible: grow and shrink are supported. Btrfs is a big leap past ext4 and XFS because it supports features such as: Copy-on-write; Subvolumes, snapshots, and rollbacks; Online defragmentationEl tipo de archivo Btrfs admite un tamaño de partición de hasta 16 EIB (Exibyte). Vide. Btrfs is especially nice for storing games because of deduplication, ZSTD compression (which ended up saving me about. ZFS also has more options for caches and such things than EXT4. It is the default file system in RHEL 6, Debian 7, Ubuntu 18 and so on. 但无论如何，各个文件系统都需要存储这三类信息，因为这是内核规定的（见下）。. EXT4 lacks more robust features but is stable and well-supported on all Linux operating systems. Because ext4 can't beat btrfs when it comes to snapshot/delete. Otherwise, I don't think you'd notice the performance difference. XFS is about as mainline as a non-ext filesystem gets under Linux. Outside of that discussion the question is about specifically the recovery speed of running fsck / xfs_repair against any volume formatted in xfs vs ext4, the backup part isnt really relevent back in the ext3 days on multi TB volumes u’d be running fsck for days!Btfs not meant to replace ext4, they are in a different category, ext4 is simple, old and stable while btrfs brings new ideas and goes into very different direction. XFS does not require extensive reading. 10. This pre-dates xfsprogs 3. If you are looking for advanced features such as data checksumming, snapshots, and data deduplication, then Btrfs may be the better option. all kinds for nice features (like extents, subsecond timestamps) which ext3 does not have. Have snapper to create pre/post BTRFS and LVM snapshots. More uniquely, checksumming can detect errors in the data itself. As modern computing gets more and more advanced, data files get larger and more. because it spans multiple partitions, it's less likely to fill up your hard drive. . For the adventurous: you can define block devices on btrfs and use ext4 on those block devices (ext4 on btrfs). Nowadays btrfs is very stable and the tools to recover from fs corruption have been getting much better as well. XFS is better larger files and long-term maintaince and stability. The fastest for the SATA/USB tests was XFS followed quickly by EXT4 and then F2FS. BTRFS stands for “B tree File System,” and it is a next-generation filesystem designed specifically for Linux operating systems. I was using NTFS due to compatibility. In fact, BTRFS is also a copy-on-write system to support fault tolerance and file recovery, and provides easy management. ago. Here are a few other differences: Features: Btrfs has more advanced features, such as snapshots, data integrity checks, and built-in RAID support. The XFS one on the other hand take around 11-13 hours!Reviews of EXT4, EXT3, XFS, BTRFS, and ZFS. However ZFS does come at one major downside, it needs more resources in just about every way one can imagine, ZFS is best with more disks, more RAM, more CPU, more Bandwidth, more SSD’s for caching…. For SSDs, F2FS really is a hands down winner still, although EXT4 and XFS are catching up, they still lose. Let's go over File Systems in this video. An efficient file system is necessary for everyday system processes. Find a motherboard with enough drive ports or real sata controllers to run all the drives. It's a 64-bit, journaling filesystem that has been built into the Linux kernel since 2001 and offers high performance for large filesystems and high degrees of concurrency (i. ZFS isn't native to Linux, nor is it GPL compatible, but it works fairly well and is a stable file system. 這裡有 4 個關於 EXT4 和 Btrfs 的附加問題。在這裡查看答案。 1. User quotas for each shared folder. 对于一些文件系统如Ext4等，在硬盘格式化时就全部确定了，而对于XFS则是动态生成的，BtrfS则是更特别的动态实现。. Snapraid says if the disk size is below 16TB there are no limitations, if above 16TB the parity drive has to be XFS because the parity is a single file and EXT4 has a file size limit of 16TB. Here are some key differences between them: XFS is a high-performance file system that Silicon Graphics originally developed. 1. After deciding to use LVM2 as volumemanager on our servers there was also the wish for an online resizeable filesystem. to get a significantly faster result than xfs. file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4, F2FS, and XFS file-system benchmarks on a speedy WD_BLACK SN850 NVMe. As others have said, btrfs is newer and offers a few advanced features for backups (snapshots) and data integrity. But it's slow when used with fsync -intensive programs such as dpkg (I know eatmydata and the crappy apt-btrfs-snapshot programs) and I won't setup a. Pros: Individual file size: 16GB to 2TB. Use XFS for your array drives and Btrfs for your cache pool. Various internet sources suggest that XFS is faster and better, but taking into account that they also suggest that EXT4 is. Though personally I'd still go with ext4 primarily because despite recognizing some potential benefits of btrfs, I really don't see them as important for how I use my computers. The major difference between ext4 and XFS file systems is that the ext4 file system works better for fewer size files (single write/read thread) while the XFS works more efficiently for larger files (multiple read/write threads). ZFS. With ZFS ZVOLs, you can run other file systems like ext4 or xfs for special situations (like as storage for VMs) and still get snapshots/block checksumming. Ext4 te permite crear un máximo de 232 archivos. XFS still has some reliability issues, but could be good for a large data store where speed matters but rare data loss (e. This is fundamental in determining the file system’s capacity. BTRFS also had somewhat higher latency than EXT4, meaning that it took longer for files to be accessed on the file system. Comparison of archive formats. Offizieller Beitrag. Ext4 is built on older technology, so it lacks modern file-system features found in systems like E2FS and BtrFS. But EXT4 is mature, rock solid, and completely reliable, and the standard for most of the linux world. But I would still refrain from using it on the deck due to the case folding trouble. So now I can boot up into a snapshot.
