I have a filesystem shared by several systems mounted on 2 ceph nodes
with a 3rd as a reference monitor.
It's been used for a couple of months now but suddenly the root
directory for the mount has become inaccessible and requests to files in
it just hang, there's no ceph errors reported before/after and
subdirectories of the directory can be used (and still are currently
being used by VM's still running from it). It's being mounted in a mixed
kernel driver (ubuntu) and centos (ceph-fuse) environment.
cluster ab3f7bc0-4cf7-4489-9cde-1af11d68a834
health HEALTH_OK
monmap e1: 3 mons at
{srv10=##:6789/0,srv11=##:6789/0,srv8=##:6789/0}, election epoch 96,
quorum 0,1,2 srv10,srv11,srv8
osdmap e2873: 6 osds: 6 up, 6 in
pgmap v2451618: 728 pgs: 728 active+clean; 128 GB data, 260 GB used,
3929 GB / 4189 GB avail; 30365B/s wr, 5op/s
mdsmap e51: 1/1/1 up {0=srv10=up:active}
Have done a full deep scrub/repair cycle on all of the osd which has
come back fine so not really sure where to start looking to find out
what's wrong with it.
Any ideas?
