Configure NFSv4 to allow different users read-write access

  • 772

I have an NFSv4 server (CentOS). I want to export a particular directory to two different machines (one CentOS and one Ubuntu), where users of the same uid and gid need read-write access to the mounted directory. The GID and UID are the on the clients are the same as on the server, but the user names are different.

When I try using gid=,uid= in the /etc/fstab I get mount.nfs: an incorrect mount option was specified. messages in /var/log/messages are

nfsidmap[12817]: nss_getpwnam: name 'apprepo' not found in domain 'sagrid.ac.za'

apprepo is the user name which owns the files on the server. sagrid.ac.za is of course the domain of our machines.

  1. you can enforce nfs client and server to use numeric ids by 

    echo Y > /sys/module/nfs/parameters/nfs4_disable_idmapping

    on the client and server
