-----------------------------------------------

             Summary: 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"
                 Key: CLOUDSTACK-5446
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5446
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server
    Affects Versions: 4.3.0
         Environment: Build from 4.3
            Reporter: Sangeetha Hariharan
             Fix For: 4.3.0


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"
