tl;dr: save yourself the hassle and dont. go for md-raid5/6 + (luks +) XFS. long version: Just last week we migrated our soon to be production server (6 disks) btrfs-raid10 to md-raid6+XFS, after btrfs managed to die twice in december. So cool btrfs-raid/filesystem-level-raid sounds, so broken it seems atm :( Not only did they not manage to use "common" definitions of raid - as in: md-raid being de-facto-standard, they get to define certain aspects of raid and others have to live by that ... READ THEIR DOCS + MAILING LIST! For example: when people talk about raid1 with say 4 disks, they expect that all disks have the same contents... Therefore expecting that losing 3 disks means no data loss. Well... btrfs decided to stick with some ancient definition of raid1 which is imho more like md-raid10, than md-raid1, as there are only 2 copies of data and you cant make btrfs to store more than 2 copies. Therefore losing 2/4 disks -> btrfs irrecoverably broken. btrfs-raid1 and btrfs-raid10 seem to be basically the same thing, with some imho performance optimizations (not striping vs striping), which should imho not even be user-settable as it makes no sense to go for suboptimal performance, but then again, maybe i missed some of their nearly inexistent documentation pointing out the good part of btrfs-raid1 ... Also btrfs-raid5/6 are broken and didnt even survive our in-vm-testing, before getting a chance on bare-metal. Also it seems way easier to go "full-raid-encryption" with luks + md-raid. (Our intention is to be able to send in disks to get them replaced without having to worry, that data could be easily extracted; there is an usb-stick with the luks key sticking out of every machine...) If you need some btrfs-features (snapshots <3), consider going md-raid+luks+btrfs. * Unsure if it still holds that btrfs will fail horribly if it sees its uuid on more than one disk, possibly making the full-disk-encryption-layer mandatory. br, Jan On 12/26/17 20:37, Rick Thomas wrote: > > Is btrfs mature enough to use in enterprise applications? > > If you are using it, I’d like to hear from you about your experiences — good or bad. > > My proposed application is for a small community radio station music library. > We currently have about 5TB of data in a RAID10 using four 3TB drives, with ext4 over the RAID.
