Hi, did you unmount your clients after the cluster poweroff? You could
also enable debug logs in mds to see more information. Are there any
blocked requests? You can query the mds daemon via cephadm shell or
with ad admin keyring like this:
# ceph tell mds.cephfs.storage.lgmyqv dump_blocked_ops

Eugen
Zitat von pclark6063@xxxxxxxxxxx:
Hi All,
Recently I upgraded my cluster from Quincy to Reef. Everything
appeared to go smoothly and without any issues arising.
I was forced to poweroff the cluster, performing the ususal
procedures beforehand and everything appears to have come back fine.
Every service reports green across the board except....
If i try to copy any files from a cephfs mountpoint whether kernel
or fuse the actual copy will hang. ls/stat etc all work which
indicates metadata appears fine but copying always hangs.
I can copy objects direct using the rados toolset which indicates
the underlying data exists.
The system itself reports no errors and thinks its healthy.
The entire cluster and cephfs clients are all Rocky9.
Any advice would be much appreciatd. I'd find this easier to deal
with if the cluster actually gave me an error....
