.I \-T <start timeout>
Specifies the timeout for clvmd daemon startup. If the daemon does not report

status of 5. This does NOT mean that clvmd has not started! What it means is

cause of this is an inquorate cluster though it could be due to locking
latencies on a cluster with large numbers of logical volumes. If you get the
return code of 5 it is usually not necessary to restart clvmd - it will start
as soon as that blockage has cleared. This flag is to allow startup scripts
to exit in a timely fashion even if the cluster is stalled for some reason.
