In a NFS-Ganesha HA cluster setup, for NFS clients to recover state
succesfully post failover, the NFS-servers should start with a unique
epoch value.
With NFS-Ganesha 2.3, the service accepts an option "EPOCH_EXEC" which
takes path of the script, generating epoch value. This script is executed before
starting nfs-ganesha service so that the generated epoch value is used
while bringing up the service.
This patch includes the script to be used by nfs-ganesha+gluster setup.
The epoch value is computed as follows -
- first 32-bit contains the now() time
- rest 32-bit value contains the local glusterd node uuid
