I'm a long term ZoL user that's been looking over the fence at btrfs for a long time. I've been tempted to switch since I only use ZFS mirrors (RAID 5 instability isn't a deal killer). If you don't mind me asking, how long have you been using it and have you had any stability issues?
- wtallis 5y agoI lost a bit of data circa 2013 on a BTRFS RAID5 as a result of a power loss. I rebuilt the array as RAID1 and it's been fine ever since, despite initially using only ST3000DM001 drives (most of which are now dead). I've added and removed drives more times than I can recall (some dead or dying, some just too small or slow to keep in service), migrated the array piecemeal over to an assortment of SSDs of varying sizes, recovered from mistakes like ejecting the wrong drive while the filesystem was mounted, and switched the metadata to RAID1c3, all with reasonably low downtime and no data loss. There have definitely been times I would have appreciated the space efficiency of a reliable RAID5/6 setup, but on the other hand I've made heavy use of features that ZFS doesn't have and probably never will.
