NFS permission issue

Maaz — Wed, 28 Jan 2009 12:50:30 GMT

ldap + Terminal server is nfs client

# grep nfs /etc/fstab
10.0.0.15:/share /home nfs defaults 0 0

from nfs server(linux based nfs server)
# cat /etc/exports
/share 10.0.0.0/24(rw,sync,no_root_squash)

whenever a new user created the ldap server creates the home directory for that user under /home.

Now we have to use NetApp device as a NFS server.
On ldap+terminal Server(nfs client) i mount the netapp based NFS share on /test

then I tried to copy all the data under /home to the /test(netapp based nfs share),

# cp -rvp /home /test

and I got the "Cannot preserve permission" error

please help

>>> Now we have to use NetApp device as a NFS server.

The question is, Â¿is the NetApp NFS server able to handle UNIX permissions?

Maybe, the NetApp server uses another file systme type locally that cannot preserve the Unix permissions.

For example, you will get the same error if you share via NFS a Windows directory.

Â¿Can you post the ouput of ls -la for the NFS share on the NetAPP device?

one thing I know is that the OS of the NFS storage device(NetApp) is Data ONTAP
