[ClusterLabs] nfs mount resource won't stop - lazy option ?

[Patrick Vranckx]

Hi,

I have a cluster configures as such:

Online: [ mbacktm1 mbacktm2 ]

Full list of resources:

  stonith-mbt    (stonith:fence_scsi):    Started mbacktm2
  Resource Group: group-mbt-stor
      nfs-daemon    (ocf::heartbeat:nfsserver):    Started mbacktm2
      mount_admnfs    (ocf::heartbeat:Filesystem):    Started mbacktm2
  Resource Group: group-secondary-gateway
      mount_admnfs_1    (ocf::heartbeat:Filesystem):    Started mbacktm1


A daemon NFS is started on one node, a filesystem is exported and 
mounted on both node.

If the node running the nfs server crashes, reboots or is fenced, the 
resource "mount_admnfs_1" on the other node won't stop because the nfs 
server will not respond (unable to unmount the filesystem anymore)

In such a situation without pacemaker, one can do a "umount -l" to solve 
the problem.

Is there a solution  for Pacemaker ?

Best regards,

Patrick
