Hi, On a new host, I am running into exactly the same scenario. I have a host with an oVirt-managed GlusterFS volume (single brick on local disk in distribute mode) on an XFS file system. I think I have found the root cause, but I doubt I can fix it. Around the time of the VMs going paused, there seemed to be a glusterfsd restart: > [2014-12-18 01:43:27.272235] W [glusterfsd.c:1194:cleanup_and_exit] (--> 0-: received signum (15), shutting down > [2014-12-18 01:43:27.272279] I [fuse-bridge.c:5599:fini] 0-fuse: Unmounting '/rhev/data-center/mnt/glusterSD/onode3.isaac.local:data02'. > [2014-12-18 01:49:36.854339] I [MSGID: 100030] [glusterfsd.c:2018:main] 0-/usr/sbin/glusterfs: Started running /usr/sbin/glusterfs version 3.6.1 (args: /usr/sbin/glusterfs - > -volfile-server=onode3.isaac.local --volfile-id=data02 /rhev/data-center/mnt/glusterSD/onode3.isaac.local:data02) > [2014-12-18 01:49:36.862887] I [dht-shared.c:337:dht_init_regex] 0-data02-dht: using regex rsync-hash-regex = ^\.(.+)\.[^.]+$ > [2014-12-18 01:49:36.863749] I [client.c:2280:notify] 0-data02-client-0: parent translators are ready, attempting connect on transport So I thought I'd check /var/log/messages for potential sources of the SIGTERM, and I found this: > Dec 18 02:43:26 onode3 kernel: supervdsmServer[1960]: segfault at 18 ip 00007faa89951bca sp 00007fa355b80f40 error 4 in libgfapi.so.0.0.0[7faa8994c000+18000] > Dec 18 02:43:27 onode3 systemd: supervdsmd.service: main process exited, code=killed, status=11/SEGV > Dec 18 02:43:27 onode3 systemd: Unit supervdsmd.service entered failed state. > Dec 18 02:43:27 onode3 journal: vdsm jsonrpc.JsonRpcServer ERROR Internal server error > Traceback (most recent call last): > File "/usr/lib/python2.7/site-packages/yajsonrpc/__init__.py", line 486, in _serveRequest > res = method(**params) > File "/usr/share/vdsm/rpc/Bridge.py", line 266, in _dynamicMethod > result = fn(*methodArgs) > File "/usr/share/vdsm/gluster/apiwrapper.py", line 106, in status > return self._gluster.volumeStatus(volumeName, brick, statusOption) > File "/usr/share/vdsm/gluster/api.py", line 54, in wrapper > rv = func(*args, **kwargs) > File "/usr/share/vdsm/gluster/api.py", line 221, in volumeStatus > data = self.svdsmProxy.glusterVolumeStatvfs(volumeName) > File "/usr/share/vdsm/supervdsm.py", line 50, in __call__ > return callMethod() > File "/usr/share/vdsm/supervdsm.py", line 48, in <lambda> > **kwargs) > File "<string>", line 2, in glusterVolumeStatvfs > File "/usr/lib64/python2.7/multiprocessing/managers.py", line 759, in _callmethod > kind, result = conn.recv() > EOFError > Dec 18 02:43:27 onode3 systemd: supervdsmd.service holdoff time over, scheduling restart. > Dec 18 02:43:27 onode3 systemd: Stopping Virtual Desktop Server Manager... > Dec 18 02:43:27 onode3 systemd: Stopping "Auxiliary vdsm service for running helper functions as root"... > Dec 18 02:43:27 onode3 systemd: Starting "Auxiliary vdsm service for running helper functions as root"... > Dec 18 02:43:27 onode3 systemd: Started "Auxiliary vdsm service for running helper functions as root". > Dec 18 02:43:27 onode3 journal: vdsm IOProcessClient ERROR IOProcess failure > Traceback (most recent call last): > File "/usr/lib/python2.7/site-packages/ioprocess/__init__.py", line 107, in _communicate > raise Exception("FD closed") > Exception: FD closed I guess I'll file a bug report.
