> We need to have proper synchronization between Snapshot delete/GC and other
> Snapshot jobs e.g. reads from Snapshots and Snapdiff. Snapdiff is
> particularly important case since it could be a long running job and in the
> middle of the job, Snapshot delete/GC can kick in.
> We should also have a uniform behavior in the cluster in case of a failover
> and concurrent Snap-diff/Deletes. It should not happen that a leader OM node
> returns certain result to a client but after a failover the new OM leader
> returns different result.
