Hi, I am using NFS storage, although it is local. Looking in to the NFS problems further, I read the NFS troubleshooting section of the oVirt wiki and made a few changes. nfs-check.py gives me the following: ------------------------------------------------------------------ Current hostname: bigserver - IP addr 10.0.0.154 Trying to /bin/mount -t nfs 10.0.0.154:/home/vm/data/data... Executing NFS tests.. Removing vdsmTest file.. Status of tests [OK] Disconnecting from NFS Server.. Done! ------------------------------------------------------------------ Success! Or so it seems, because when the machine boots there are no NFS shares mounted. When I attempt to activate the data centre in the oVirt web admin tool, the activation fails but an NFS share is mounted: ------------------------------------------------------------------ 10.0.0.154:/home/vm/data/data on /rhev/data-center/mnt/10.0.0.154:_home_vm_data_data type nfs (rw,relatime,vers=3,rsize=1048576,wsize=1048576,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,mountaddr=10.0.0.154,mountvers=3,mountport=20048,mountproto=udp,local_lock=none,addr=10.0.0.154) ------------------------------------------------------------------ Here is the engine.log associated with trying to activate the data centre: ------------------------------------------------------------------ 2013-04-27 22:45:01,229 INFO [org.ovirt.engine.core.bll.storage.ActivateStorageDomainCommand] (pool-5-thread-44) Lock Acquired to object EngineLock [exclusiveLocks= key: org.ovirt.engine.core.bll.storage.ActivateStorageDomainCommand val ue: 025062dd-d69e-40ac-9031-c080b51647ae , sharedLocks= ] 2013-04-27 22:45:01,231 INFO [org.ovirt.engine.core.bll.storage.ActivateStorageDomainCommand] (pool-5-thread-44) Running command: ActivateStorageDomainCommand internal: false.

As I mentioned earlier, in this instance there were no NFS shares mounted when the machine booted and none were mounted until I tried to activate the data centre. I subsequently rebooted the server after making some changes to nfsmount.conf, and upon booting the ISO share was mounted. Intrigued, I rebooted again and both the ISO and Export shares were mounted, but not the data share. Do you - or does anybody - have any further insight? Thanks for your help so far - looking in to the NFS side of things is giving some interesting results, and I'm sure that we're on the path to great success. --Steven.
