Hi ceph users,
If I understand correctly the "min_compat_client" option in the OSD map
was replaced in Luminous with "require_min_compat_client".
After upgrading a cluster to Luminous and setting
set-require-min-compat-client to jewel, the min_compat_client option
still shows as hammer.

let me add Peter, he probably can answer your question.

hi there,
while debugging metadata servers reporting slow requests, we took a stab
at pinning directories of a cephfs like so:
setfattr -n ceph.dir.pin -v 1 /tubfs/kubernetes/
setfattr -n ceph.dir.pin -v 0 /tubfs/profiles/
setfattr -n ceph.dir.pin -v 0 /tubfs/homes
on the active mds for rank 0,

Thanks,
I moved back to crush-compat mapping, the pool that was at "90% full"
is now under 76% full.
Before doing that, I had the automatic balancer off, and ran 'ceph
balancer optimize test'. It ran for 12 hours before I killed it. In
upmap mode, it was "balanced" or at least as balanced as it

Here's some more information on this issue.
I found the MDS host not to have any load issues, but other clients who
have the FS mounted cannot execute statfs/fstatfs on the mount, since
the call never returns while my rsync job is running. Other syscalls
like fstat work without problems.

Hi,
There have been various stability issues with the MDS that I reported a
while ago and most of them have been addressed and fixes will be
available in upcoming patch releases. However, there also seem to be
problems on the client side, which I have not reported so far.

We have a cluster running CephFS with metadata on SSDs and data split
between SSDs and OSDs (main pool is on HDDs, some subtrees are on an SSD
