* snapshot/scheduling: A cron based scheduler for snapshot schedulingAvra Sengupta2015-03-184-0/+803
GlusterFS volume snapshot provides point-in-time copy of a GlusterFS volume. Currently, GlusterFS volume snapshots can be easily scheduled by setting up cron jobs on one of the nodes in the GlusterFS trusted storage pool. This has a single point failure (SPOF), as scheduled jobs can be missed if the node running the cron jobs dies. The solution to the above problems is addressed in this patch. The snap_scheduler.py helper script expects the user to install the argparse python module before using it.
