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.
