[oneadmin@opennebula01 .ssh]$

SOLUTION

Ensure that the mount is possible and that the NFS daemon is running on OpenNebula:

/etc/fstab
192.168.0.70:/var/lib/one/  /var/lib/one/  nfs   soft,intr,rsize=8192,wsize=8192,noauto

[oneadmin@opennebula01 .ssh]$ cat /etc/exports
/var/lib/one/ *(rw,sync,no_subtree_check,root_squash)
[oneadmin@opennebula01 .ssh]$ ps -ef|grep -i nfs
oneadmin 12481  9559  0 00:22 pts/0    00:00:00 grep –color=auto -i nfs
[oneadmin@opennebula01 .ssh]$
[oneadmin@opennebula01 .ssh]$

[root@opennebula01 ~]# systemctl start nfs
[root@opennebula01 ~]#

Alos if you note above, I had used noauto in /etc/fstab.  Change to auto if you trust the NFS won't lock up your boot order getting stuck on NFS.

Cheers,
TK
