edison su resolved CLOUDSTACK-5370. ----------------------------------- Resolution: Fixed when error happened during snapshot, we need to delete the snapshot on primary storage and also in db. > Xenserver - Snapshots - vhd entries get accumulated on the primary store when > snapshot creation fails becasue of not being able to reach the secondary > store. > ------------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: CLOUDSTACK-5370 > URL: https://issues.apache.org/jira/browse/CLOUDSTACK-5370 > 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 > Assignee: edison su > Priority: Critical > Fix For: 4.3.0 > > > Set up: > Advanced Zone with 2 Xenserver 6.2 hosts: > 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. ( In my case i stopped the nfs server) > 4. Bring the Secondary storage server up after 12 hours. ( In my case started > the nfs server). > When secondary server was down (NFS server down) for about 12 hours , I see > that hourly snapshots get attempted every hour and fail with > “CreatedOnPrimary" state . I see many entries being created on the primary > store ( I see 120 entries , but I have only 14 vms). > We accumulate 2 vhd files on the primary store for every snapshot that is > attempted. > When secondary store is brought up , and when another snapshot is attempted > and it succeeds, we see the vhd files are all being cleared out. > This is a problem that we accumulate so many vhd files ( In case of vmware > and kvm where there are no delta snapshots this size would be significantly > higher) on primary store. -- This message was sent by Atlassian JIRA (v6.1.4#6159)
