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. So we’re about 75% full, growing at the rate of about
1TB/year, so we’ll run out of space by the end of 2018.
I’m proposing to go to three 6TB drives in a btrfs/RAID5 configuration. This
would give us 12TB of usable data space and hold off til the end of 2024 before
needing the next upgrade.
Will it work? Would I be safer with ext4 over RAID5?
Take a look at ZFS before you decide -- either ZFS on Linux or FreeBSD:
https://packages.debian.org/stretch/zfs-dkms
https://www.freebsd.org/
I would suggest building a ZFS pool with two 8 TB mirrored drives. When
you want more space, add another mirrored pair.
Live compression and live de-duplication are useful features of ZFS, but
the killer features are live snapshots and live replication.
