Hi,
Just a very quick and simple reply:
XFS has *always* treated us nicely, and we have been using it for a VERY
long time, ever since the pre-2000 suse 5.2 days on pretty much all our
machines.
We have seen only very few corruptions on xfs, and the few times we
tried btrfs, (almost) always 'something' happened. (same for the few
times we tried reiserfs, btw)
So, while my story may be very anecdotical (and you will probably find
many others here claiming the opposite) our own conclusion is very
clear: we love xfs, and do not like btrfs very much.

Hi all,
I don't have a good track record with XFS since I got rid of ReiserFS a
long time ago. I decided XFS was a good idea on servers, while I tested
BTRFS on various less important devices.
So far, XFS betrayed me far more often (a few times) than BTRFS
(never).
Last time was yesterday, on a root filesystem with "Block out of range:
block 0x17b9814b0, EOFS 0x12a000" "I/O Error Detected. Shutting down
filesystem" (shutting down the root filesystem is pretty hard).
Some threads on this ML discuss a similar problem, related to
partitioning and logical sectors located just after the end of the
partition. The problem here does not seem to be the same, as the
requested block is very far out of bound (2 orders of magnitude too
far), and I use a recent Debian stock kernel with every security patch.
My question is : should I trust XFS for small root filesystems (/,
/tmp, /var on LVM sitting within md-RAID1 smallish partition), or is
BTRFS finally trusty enough for a general purpose cluster (still root
et al. filesystems), or do you guys just use the distro-recommended
setup (typically Ext4 on plain disks) ?
Debian stretch with 4.9.110-3+deb9u4 kernel.
Ceph 12.2.8 on bluestore (not related to the question).
