-----------------------------------------------
Summary: Not able to take snapshot becasue of secondary_storage limit of 400 gb exceeded even though we have not really consumed this limit in secondary store.
Key: CLOUDSTACK-5406
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5406
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
Priority: Blocker
Fix For: 4.3.0
Set up:
Xenserver setup with 2 NFS secondary stores.
1 account having 21 Vms.
I am using the the default "secondary_storage" limit which is 400 gb.
Started hourly snapshot policy for all the ROOT volumes of the Vms which was created from a template of size 20 gb. The actual used up size is 12 GB.
When snapshot gets created , the full snapshot size is ~6.7 GB.
After only 2 snapshots of ROOT volume , I hit the following excepton:
“2013-12-06 00:00:48,298 WARN [c.c.s.s.SnapshotSchedulerImpl] (SnapshotPollTask:ctx-a7ccb50a) Scheduling snapshot failed due to com.cloud.exception.ResourceAllocationException: Maximum number of resources of type 'secondary_storage' for account name=test-TestParallelVolumeSnasohots-273V8U in domain id=1 has been exceeded.”
How are we calculating this limit ? Do we query the actual secondary store / do we calculate based on the ROOT volume size and # of Snapshots.
In case of Xenserve , we have Delta snapshots.We should not be
