hi guys,I met a problem while creating "New Domain" iso/nfs storage,it prints "Error while executing action New NFS Storage Domain: Storage domain remote path not mounted" and the error code is 477.anyone can give some hits? I followed the " http://wiki.ovirt.org/wiki/Troubleshooting_NFS_Storage_Issues" and find that the vdsm user can't now use mount."mount: only root can do that" the version I use: oVirt Engine Version: 3.1.0-2.fc17 oVirt Node Hypervisor 2.5.4-0.1.fc17 the error log: *2012-11-08 09:15:00,004 INFO [org.ovirt.engine.core.bll.AutoRecoveryManager] (QuartzScheduler_Worker-77) Checking autorecoverable storage domains done* *2012-11-08 09:17:28,920 WARN [org.ovirt.engine.core.bll.GetConfigurationValueQuery] (ajp--0.0.0.0-8009-2) calling GetConfigurationValueQuery (StorageDomainNameSizeLimit) with null version, * *using default general for version* *2012-11-08 09:17:29,333 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.ValidateStorageServerConnectionVDSCommand] (ajp--0.0.0.0-8009-3) [7720b88f] START, ValidateStorageServerConnectionVDSCommand(vdsId = 12bcf124-29a4-11e2-bcba-00505680002a, storagePoolId = 00000000-0000-0000-0000-000000000000, storageType = NFS, connectionList = [{ id: 6556c55d-42a4-4dcc-832c-4d8987ebe6bd, connection: 200.200.101.219:/usr/lwq/iso };]), log id: 52777a80* *2012-11-08 09:17:29,388 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.ValidateStorageServerConnectionVDSCommand] (ajp--0.0.0.0-8009-3) [7720b88f] FINISH, ValidateStorageServerConnectionVDSCommand, return: {6556c55d-42a4-4dcc-832c-4d8987ebe6bd=0}, log id: 52777a80* *2012-11-08 09:17:29,392 INFO [org.ovirt.engine.core.bll.storage.AddStorageServerConnectionCommand] (ajp--0.0.0.0-8009-3) [7720b88f] Running command: AddStorageServerConnectionCommand internal: false.
