Question

NFS Mount - Can't create folders with "root" user

Asked by: dpora1979

I created an NFS mount between two Sun Solaris 10 servers.

Server1 - shared "/data/lfs"

Server2 - mounted "Server1:/data/lfs" to "/data/lfs_copy"

Both of these shares are owned by root on their prospective servers. Why can't I create folders from Server2 on "/data/lfs_copy". I receive a permissions denied error!

I know this works because I've done this in the past, what am I missing?? How do I get this to work?? Should I use another method to share remote file-systems?

Thanks!

Hi,

the filesystem in question needs to be exported with the "no_root_sqash" option.

please have a look at 3.2.1 for nfs server options (i.e. no_root_sqash as recommended by woolmilkporc) for the exported dir:

Being root on Server2 is not the same as being root on Server1, for security - You need to explicitly grant root-equivalent access to the NFS share to NFS client systems.

The Solaris equivalent of Linux "no_root_squash" would be "-o root=Server2" in your case, used either as an option to the "share" command or in /etc/dfs/dfstab
