Basically, I meant to verify the access by ssh, but I want to verify something following your detailed reply:
According to [1], in order to set a NetApp NFS server, the required steps should look like this: # mount NetApp_NFS:/path/to/export /mnt # chown -R 36.36 /mnt # chmod -R 755 /mnt # umount /mnt Which is quite similar to the steps you've mentioned, except the last step of unmounting: Unmount the 10.214.13.64:/ovirt_production I think that you had to unmount /mnt/rhevstore instead. Can you please verify?
