glusterfs.git/extras/ganesha/scripts/generate-epoch.py, branch v3.10.2 ganesha: Include a script to generate epoch value 2016-03-21T08:15:04+00:00 Soumya Koduri skoduri@redhat.com 2016-03-14T11:06:33+00:00 9879c4e543e37de753b2650ab6fcd427afb0169d 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: 1317902 Signed-off-by: Soumya Koduri <skoduri@redhat.com> Reviewed-on: http://review.gluster.org/13744 Smoke: Gluster Build System <jenkins@build.gluster.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: jiffin tony Thottan <jthottan@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> 
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
