What's wrong with btrfs?

[–] [email protected] 10 points 2 months ago (6 children)

My only gripe with btrfs is that I've had systems come down from a single drive failure in raid quite "often" when compared to other FS.

ZFS is a ram hog but I always could do a live resilvering without downtime.

btrfs's RAID features are not production-ready, and at this point I doubt they ever will be. See:

https://www.phoronix.com/news/Btrfs-Warning-RAID5-RAID6

ZFS is definitely more robust.

It is true for raid 5 & 6. Raid 0, 1, and 10 are supposed to be production ready. I use raid 10 only with btrfs, anything else and I use zfs or mdadm.
