  • Jul 27, 2015 路 But, btrfs is still limited in it's recovery ability in UnRAID because it's a filesystem applied to each individual disk vs. a typical btrfs array. Unless you enable multiple copies per disk, btrfs can detect the error, but not always repair it.

ZFS is a combined file system and logical volume manager designed by Sun Microsystems. Starting with Proxmox VE 3.4, the native Linux kernel port of the ZFS file system is introduced as optional file system and also as an additional selection for the root file system.
Functionality wise you want btrfs. But even though raid 0/1 is good, from what I've read I wouldn't recommend raid 5/6 on a system under heavy use that you don't have backup of just yet.
On unraid it was a bit of a hack to get tvheadend to run on it. Also unraid uses riserfs (or did at the time) so you would need a copy of Ubuntu 12.04 if you wanted to read the disks. Where as my raid 5 install could be moved to my ubuntu machine if needed and it would just work. A filesystem like BTRFS (or, presumably, ZFS) can work out the details automatically if you set it up in RAID-1 mode. But having one side of the mirror spread across 9 drives makes failure laughably likely, to the point where you're paying performance penalties for nothing.

Copy-on-write (COW), sometimes referred to as implicit sharing or shadowing, is a resource-management technique used in computer programming to efficiently implement a "duplicate" or "copy" operation on modifiable resources. I'd go with UnRAID long before ZFS, especially now considering UnRAID supports btrfs and xfs. It also supports Docker, which is pretty cool, too. N. NeverDie
