Hello, Since a recent reboot, my default data storage pool has been inactive and attempts to activate it fail. Installed RPMs: vdsm-4.9.6-0.150.git63061a9.el6.x86_64 ovirt-engine-3.1.0_0001-1.8.el6.x86_64 Relevant-looking output in the vdsm.log file (more @ http://pastebin.com/raw.php?i=cYaFLPEF): Thread-68465::ERROR::2012-05-09 14:05:00,491::task::853::TaskManager.Task::(_setError) Task=`937d1fa9-4636-42f1-a6cb-c4cc56b9f2fd`::Unexpected error Traceback (most recent call last): File "/usr/share/vdsm/storage/task.py", line 861, in _run return fn(*args, **kargs) File "/usr/share/vdsm/logUtils.py", line 38, in wrapper res = f(*args, **kwargs) File "/usr/share/vdsm/storage/hsm.py", line 526, in getSpmStatus pool = self.getPool(spUUID) File "/usr/share/vdsm/storage/hsm.py", line 263, in getPool raise se.StoragePoolUnknown(spUUID) StoragePoolUnknown: Unknown pool id, pool not connected: ('af5bcc86-898a-11e1-9632-003048c85226',) Thread-68465::DEBUG::2012-05-09 14:05:00,491::task::872::TaskManager.Task::(_run) Task=`937d1fa9-4636-42f1-a6cb-c4cc56b9f2fd`::Task._run: 937d1fa9-4636-42f1-a6cb-c4cc56b9f2fd ('af5bcc86-898a-11e1-9632-003048c85226',) {} failed - stopping task The share /is/ mounted on the node: # mount | grep cmcd-db-vip cmcd-db-vip.in.hwlab:/vmstore/ovirt on /rhev/data-center/mnt/cmcd-db-vip.in.hwlab:_vmstore_ovirt type nfs (rw,soft,nosharecache,timeo=600,retrans=6,nfsvers=3,addr=10.0.10.13) # ls -l /rhev/data-center/mnt/cmcd-db-vip.in.hwlab:_vmstore_ovirt/ total 0 drwxr-xr-x 5 vdsm kvm 45 Apr 13 12:23 4ddb9dce-1ede-459a-9b9f-52b035622517 drwxr-xr-x 5 vdsm kvm 45 Apr 12 16:17 4ea29e75-ab27-4bc9-bc46-1740d07f4cba drwxr-xr-x 5 vdsm kvm 45 Apr 19 11:40 e12a0f53-ee72-44bc-ad26-93f9b4613c6c The closest google turns up is a thread from March, in which there was some mention of a change in the way metadata is read.
