Min Chen commented on CLOUDSTACK-5446:
--------------------------------------
When backup failed, snapshot entry should become Error state instead of
CreatedOnPrimary to distinguish two different states. Also fixed the code to
always clean up snapshot on primary even in case of exception happening in
backing up stage.
> 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
> "there is other active snapshot tasks on the instance to which the volume is
> attached"

> 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:
>
