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"
