> KVM - Secondary Store down - Even after secondary store is brought back up after being
down for few hours ,  snapshot jobs do not get triggered with reason "here is other active
snapshot tasks on the instance to which the volume is attached, please try again later"
> Set up:
> Advanced Zone set up with 2 KVM (RHEL 6.3) hosts.
> Steps to reproduce the problem:
> 1. Deploy 5 Vms in each of the hosts with 10 GB ROOT volume size , so we start with 10
Vms.
> 2. Start concurrent snapshots for ROOT volumes of all the Vms.
> 3. Shutdown the Secondary storage server when the snapshots are in the progress.
> 4. Bring the Secondary storage server up after  ~ 12 hours.
> When the secondary storage was down:
> The snapshot jobs that were in progress  timed out after 6 hours.
> Even after this , I do not see the hourly snapshots being scheduled due to the following
reason:
>  
> 2013-12-10 13:07:49,285 WARN  [c.c.s.s.SnapshotSchedulerImpl] (SnapshotPollTask:ctx-cf0775f7)
Scheduling snapshot failed due to com.cloud.utils.exception.CloudRuntimeException: There is
other active snapshot tasks on the instance to which the volume is attached, please try again
later
> Even after the secondary storage was brought up , there is no hourly snapshots being
scheduled due to the same reason - "com.cloud.utils.exception.CloudRuntimeException: There
is other active snapshot tasks on the instance to which the volume is attached, please try
again later"
