Hi,
I've deployed ceph on a number of nodes in our compute cluster (Ubuntu 14.04
Ceph Firefly 0.80.9). /ceph is mounted via ceph-fuse.
From time to time some nodes loose their access to cephfs with the following
error message:
# ls /ceph
ls: cannot access /ceph: Transport endpoint is not connected
looks like ceph-fuse was crashed. please check if there is any crash
related information in the client log files
The ceph client log contains the entries like:
2015-04-22 14:25:42.834607 7fcca6fa07c0 0 ceph version 0.80.9
(b5a67f0e1d15385bc0d60a6da6e7fc810bde6047), process ceph-fuse, pid 156483

The lines above are the complete log output in ceph-client.admin.log for
the day the filesystem was mounted (04/22) and the day it became
unavailable (04/26). The problem is not reproducible (or the trigger is
not known yet) and has affected several hosts during the last weeks.
I'll update to hammer today, maybe it resolves this problem.
Best regards,
Burkhard Linke
