I know 2 approaches.
1. Use NFS hard mounting option - it will never give error to sanlock and it 
will be waiting until NFS is recovered (never tries this one, but in theory 
might work)
2. Change the default sanlock timeout (last time I tried that - it didn't work) 
. You might need help from Sandro or Sahina for that option.
