** Description changed: + [ Impact ] + + the nfsserver resource agent unmounts /var/lib/nfs as part of its stop + process. WHen such unmount operation fails and re rest of the stop + operation succeeds, the whole stop operation is reported as being + successful. However, it should fail in such cases, otherwise, this may + hider recovery of other resources. + + [ Test Plan ] + + Install the relevant packages: + + # apt update && apt install -y pacemaker corosync resource-agents nfs- + kernel-server pcs + + Create an ocf:heartbeat:nfsserver resource with a nfs_shared_infodir + + # pcs resource create nfs-daemon ocf:heartbeat:nfsserver + nfs_shared_infodir=/mnt/nfs_shared_infodir + + Hold open /var/lib/nfs: + + # touch /var/lib/nfs/testfile + # exec 3>/var/lib/nfs/testfile + + Stop the resource: + + # pcs resource debug-stop nfs-daemon + + Affected systems should report success when stopping the resource + (Operation stop for nfs-daemon (ocf:heartbeat:nfsserver) returned: 'ok' (0)). + + Also check that /var/lib/nfs is still mounted: + + # mount | grep /var/lib/nfs + + Fixed systems should fail to stop the resource. + + [ Where problems could occur ] + + This change consists in having the nfs resource agent to return an error + in case specific mounts are not unmounted upon stopping the agent. If + any user custom workflows (erroneously) rely in such behavior (having + the stop action to succeed even when unmounting fails), then this will + break such workflow. In this specific case, we should just point those + users to this bug. + + [ Other Info ] + + This bug was originally reported (and fixed upstream) through + https://bugzilla.redhat.com/show_bug.cgi?id=1924363.
