[Users] "permission settings on the specified path do not allow access to the storage"

[Shu Ming]

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?
