or better: 4 disks for RAID10 (striping + mirroring = speed + safety).at least 2 disks for RAID1 (mirroring = safety).computers with massive computational resources (CPUs, RAM & disks).Is zfs “better” on/for servers? (this user says: even on single disk systems, zfs is “better” as it prevents bit-rot-file-corruption) say?: will ZFS ever be GPL 2.0 or 3.0? (better 2.0)Įxt4 is good for notebooks & desktops & workstations (that do regular backups on a separate, external, then disconnected medium) It will have to recompile for every kernel update! so… what does Mr A. For users of enterprise storage systems, Btrfs provides file system integrity after unexpected power loss, helps prevent bitrot, and is designed for high-capacity and high-performance storage servers.” (src: )īachelor projects are written about btrfs vs zfs ( 2015) warning! It allows taking subvolume snapshots and supports offline storage migration while keeping snapshots. “Btrfs Storage Technology: The copy-on-write (COW) file system, natively supported by the Linux kernel, implements features such as snapshots, built-in RAID, and self-healing via checksumming for data and metadata. So at this point BtrFS is the only fs for me.” (src: comment by Russell W Behne on ) I love what BtrFS is doing for me, and I won’t downgrade to ext4 or any other fs. “Some BtrFS features outperform ZFS, to the point where I would not consider wasting my time installing ZFS on anything. It’s not only about performance but also stability and recovery flexibility that drives most to choose ZFS.” (src: comment by Rubens on ) “some functionalities in ZFS does not have parallels in other filesystems. I had many music files (ext4) corrupted during the last 10 years.” (src: comment by Bert Nijhof on ) “I need ZFS, because In the country were I live, we have 2-12 power-fails/week. This need is growing larger and larger every year that passes.” (src: comment by Tman7 on ) “Zfs is greatly needed in Linux by anyone having to deal with very large amounts of data. “it is sad – however – that licensing issues often get in the way of the best solutions being used” (src: comment by mattlach on ) Oracle is best considered an evil corporation, and anti-open source.” “after what they did to all of SUN’s open source projects after acquiring them. No looking around for a compatible RAID controller or storage device.” The fact that it is independent of RAID hardware is another bonus, because you can rescue pools on any system, if a server goes down. “The performance is good, the reliability and protection of data is unparalleled, and the flexibility is great, allowing you to configure pools and their caches as you see fit. “The whole purpose behind ZFS was to provide a next-gen filesystem for UNIX and UNIX-like operating systems.” (src: comment by JohnK3 on ) It also eliminates the need for hardware RAID controllers.The ZFS architecture eliminates an entire layer of translation - and along with it, an entire class of metadata (volume LBAs).and a ton of other useful stuff in just 80,000 lines of code.”.In a nutshell, that’s what ZFS does: it telescopes the storage stack. When you rearrange the terms of a series so that they cancel out, it’s called telescoping - by analogy with a collapsable hand-held telescope. “FOSS means that effort is shared across organizations and lowers maintenance costs significantly” (src: comment by JohnFOSS on ) ZFS is probably THE most controversial filesytem in the known universe: THE most controversial filesytem in the known universe: ZFS – so ext4 is faster on single disk systems – btrfs with snapshots but without the zfs licensing problems Volunteer computing / World Community Grid / WCG.Virtualization / KVM / VirtualBox / xenserver.USV / UPS / Power / PowerSupply / Energie.Space / Cosmos / Kosmos / Galaxy / Galaxie / Weltall.raspberry / carambola / atmel / embedded linux.Propaganda / FakeNews / InfoWars / InformationWarfare.project management / project planing / git.Privacy Protection / Datenschutz / DSGVO / GDPR.Privacy / convenience vs surveillance / Orwell.Photographie / Photography / Pictures / Pics.Innovation / Civilisation / Zivilisation / Culture.gute nachrichten / good news / positive news.Free Hardware / OpenBios / OpenFirmware / CoreBoot / LibreBoot.database / MariaDB / MySQL / Postgress / DB.CyberSec / ITSec / Sicherheit / Security / SPAM.
