As a common slob who isn't very skilled, I like to see some commentary
from some of the pros here as to any comparison of zfs against btrfs.
* Neither one has a fsck. They both have scrub. (btrfs calls it "scan" and
zfs calls it "scrub.") (Correction ... In the latest btrfs beta, I see
there exists btrfsck, but I don't know if it's a full fledged fsck. Maybe
it's just a frontend for scan? People are still saying there is no fsck.)
I just wanted to add something on fsck on ZFS - because for me that used
to make ZFS 'not ready for prime-time' in 24x7 5+ 9s uptime environments.
Where ZFS doesn't have an fsck command - and that really used to bug me
- it does now have a -F option on zpool import. To me it's the same
functionality for my environment - the ability to try to roll back to a
'hopefully' good state and get the filesystem mounted up, leaving the
corrupted data objects corrupted. So that if the 10-1000 files and
objects that went missing aren't required for my 24x7 5+ 9s application
to run (e.g. log files), I can get it rolling again without them
quickly, and then get those files recovered from backup afterwards as
needed, without having to recover the entire pool from backup.
cheers,
Brian
