All File Ownership shows as nobody:nobody in NFSv4 Mount
All File Ownership shows as nobody:nobody in NFSv4 Mount.
From the client, the mounted NFSv4 share has ownership for all files and directories listed as nobody:nobody instead of the actual user that owns them on the NFSv4 server, or who created the new file and directory. Following Error also appearing in the /var/log/messages :
nfsidmap[60565]: nss_getpwnam: name 'oracle@exampleserver.local' does not map into domain 'srv.local
Solution:
Edit the /etc/idmapd.conf file and add the "Domain = exampleserver.local" in the General section on both the client and server.
On the RHEL 6.2 and older, we need to restart the rpcidmapd service and remount the NFSv4 filesystem.
# service rpcidmapd restart
# mount -o remount <NFS Mount Point>
On RHEl 6.3 and higher, we need to clear the idmapd cache after matching Domain name and matching UID/GID's on Server and Client.
To clear the idmapd cache we need to run following command.
# nfsidmap -c
