Hi,
reading the list archives, I get the impression that XFS is the second
best alternative to btrfs. But when I start an ceph-osd on an XFS
volume, there is still a big warning:
WARNING: not btrfs or ext3. We don't currently support file systems other
than btrfs and ext3 (data=journal or data=ordered). Data may be
lost in the event of a crash.
I know that I can't use btrfs snapshots, but is it really that bad?
I'm running a recent RHEL6.2 kernel now, that has all those wonderful
optimizations, Dave Chinner was talking about.
Thanks,
Christian
