I patched the script to do a nfsd restart, based upon what the RA
nfsserver do. In this way, things works, but seems a little bit ugly...
I'm going to do some tests and then post the patch.
The patch is attached. It works, even if the solution appears to me a
little bit ugly :-)
Some notes: there is a new parameter named nfs_init_script, which by
default is /etc/init.d/nfs-kernel-server.
This nfs_init_script is used by the RA to restart the nfs daemon on the
stop operation.
When the resource is migrated, the script removes the export with
exportfs -u and then restarts the nfsd daemon.
Note that if you have two exportfs resources on the same node, i.e.
share-a-exportfs and share-b-exportfs, and you force the migration of
only share-a-exportfs, then share-b-exportfs will fail: his monitor will
not see the nfsd for a while because this is being restarted by
share-a-exportfs. Then resource share-b-exportfs will be immediately
restarted, and share-a-exportfs will be activated on the other node.
Finally, the migration will be successfully completed.
If you have any kind of suggestion to make this look better, you're welcome.
Thanks,
