[gpfsug-discuss] Mounting an nfs share on a CES node

[Hannappel, Juergen]

Hi,
I have a CES node exporting some filesystems vis smb and ganesha in a standard CES setup.
Now I want to mount a nfs share from a different, non-CES server on this CES node.
This did not work:
mount -o -fstype=nfs4,minorversion=1,rw,rsize=65536,wsize=65536 some.other.server:/some/path /mnt/
mount.nfs: mount to NFS server 'some.other.server:/some/path' failed: RPC Error: Program unavailable

Does the CES software stack interfere with the nfs client setup? It seems that at least with
rpc-statd there is some conflict:

 systemctl status rpc-statd
● rpc-statd.service - NFS status monitor for NFSv2/3 locking.
