Hi, My ovirt-engine was setup on a vm host with ip:xxx.xxx.xxx.112. And I am trying to create a new domain with ovirt-engine UI by the "Storage"--> "New Domain". And the following error happened. However I can mount the xxx.xxx.xxx.110:/data by "mount -t nfs xxx.xxx.xxx.110:/data /mnt" manually in the ovirt-engine host, also a new file can be created under the mounted directory with "touch xx". It looks to me that there is no permission problem when I access the remote nfs path manually. So does ovirt-engine enforce additional permission check beside the normal unix file permission check here? ---- [root@ovirt-engine-112 /]# vim /var/log/ovirt-engine/engine.log [root@ovirt-engine-112 /]# vim /var/log/ovirt-engine/engine.log 2012-03-06 00:38:51,165 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.ValidateStorageServerConnectionVDSCommand] (http--0.0.0.0-8080-6) START, ValidateStorageServerConnectionVDSCommand(vdsId = 46a83d56-66d9-11e1-8004-5254009e821b, storagePoolId = 00000000-0000-0000-0000-000000000000, storageType = NFS, connectionList = [{ id: null, connection: xxx.xxx.xxx.110:/data };]), log id: 1899002d 2012-03-06 00:38:51,297 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.ValidateStorageServerConnectionVDSCommand] (http--0.0.0.0-8080-6) FINISH, ValidateStorageServerConnectionVDSCommand, return: {00000000-0000-0000-0000-000000000000=469}, log id: 1899002d 2012-03-06 00:38:51,300 ERROR [org.ovirt.engine.core.bll.storage.NFSStorageHelper] (http--0.0.0.0-8080-6) The connection with details xxx.xxx.xxx.110:/data failed because of error code 469 and error message is: permission settings on the specified path do not allow access to the storage. verify permission settings on the specified storage path. 2012-03-06 00:38:51,300 WARN [org.ovirt.engine.core.bll.storage.AddStorageServerConnectionCommand] (http--0.0.0.0-8080-6) CanDoAction of action AddStorageServerConnection failed.
