Hello List,
i did a simple update in my CentOS 6.6 Engine (3.5) and then i rebootet it.
After that i ran into trouble.
My NFS mounts from my clients to my engine got stuck. So i unmounted them manually with: umount -f -l <path to my mount point>
Which worked. I hoped vdsm would remount it again. With no luck. So i deleted the nfs export and iso domain from the cluster.
Now i am getting this error in my vdsm log: 2c6b4422-7faa-4847-ab30-fc713d7012af::ERROR::2015-05-18 13:13:25,682::sdc::137::Storage.StorageDomainCache::(_findDomain) looking for unfetched domain

In older engine logs i was able to find out what id 036b5575-51fa-4f14-8b05-890d7807894c is: ----------------------------
2015-05-18 10:58:55,397 WARN [org.ovirt.engine.core.vdsbroker.irsbroker.IrsProxyData] (org.ovirt.thread.pool-8-thread-43) domain 036b5575-51fa-4f14-8b05-890d7807894c:EXPORT2 in problem. vds: ovirt-node01.stuttgart.imos.net
Now my Question: Why does the vdsm node not know that i deleted the storage? Has the vdsm cached this mount informations? Why does it still try to access 036b5575-51fa-4f14-8b05-890d7807894c?
Yes, the vdsm use a cache for Storage Domains, you can try to restart the vdsmd service instead of rebooting the host.
I can NOT reboot my node because i have active running vms on it.
