Got this error :
mount.nfs: rpc.statd is not running but is required for remote locking. mount.nfs: Either use '-o nolock' to keep locks local, or start statd. mount.nfs: an incorrect mount option was specified
You forgot the rpcbind service !
yum install rpcbind service rpcbind start chkconfig rpcbind on
Glad to help 😉
