[Bug 2065848] Re: An ocf:heartbeat:nfsserver resource's stop operation succeeded despite the /var/lib/nfs filesystem failing to unmount.

[Jacob Becker]

Hi 
yes, on the resource-agents side the commit is sufficient.

Steps to repoduce:

install ubuntu 22.04 with pacemaker, corosync, nfs-kernel-server and
resource-agents.

configure a ocf:heartbeat:nfsserver resource _with_ nfs_shared_infodir
parameter.

start an the try to stop the resource.
after a successful stop you will still se a mounted /var/lib/nfs. if your nfs_shared_infodir path is on a mounted resource itself, this resource cannot be stopped, since it is still mounted.

for testing purpose its sufficient to check is the mount still is there.

you most likely see a   
pacemaker-execd[]: notice: nfs_daemon_stop_0[65992] error output [ umount: /var/lib/nfs: target is busy. ] line in the log although the resource is considered stopped without error.

Kind regards 
Jacob
