mount: mount to NFS server 'IPADDRESS' failed: RPC Error: Program not registered

  • 772

I've got two Redhat5/CentOS systems which share a folder. I'm trying to change the shared folder location, but I ran into this error on the machine on which the folder is mounted...

How can I correct this? I rebooted the computer but to no avail.

Server1 - where its "mounted"

/etc/fstab
IPADDRESS2:/opt/programA/common/files    /srv/server2-share nfs rw,intr    0 0

Server2 - where its "shared"

/etc/exports
/opt/programA/common/files IPADDRESS1/28(rw,insecure,sync,no_root_squash)

Ran the following on Server2

root@server2 [~]# /etc/init.d/nfs start
root@server2 [~]# rpcinfo -p

  1. If I understand this correctly you tried to change the location of the share on the server, while a client had the NFS share mounted. In the future I would recommend unmounting the share on any client that has the share mounted. You can use the "showmount" command on the server to make sure that no one has that share mounted.
