ganesha: Include a script to generate epoch value
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 Change-Id: I876ea5a3730d7c6b40503e0fec16a4a142c54a36 BUG: 1317482 Signed-off-by: Soumya Koduri <skoduri@redhat.com> Reviewed-on: http://review.gluster.org/13716 Smoke: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: jiffin tony Thottan <jthottan@redhat.com> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>
