Subject [jira] [Commented] (CLOUDSTACK-9572) Snapshot on primary storage not cleaned up after Storage migration
Date Tue, 14 Aug 2018 00:28:00 GMT

Mike Tutkowski commented on CLOUDSTACK-9572:
--------------------------------------------

With regards to your snapshot-delete question:

As far as I know, if you migrate a volume from one primary storage to another, there should
never exist any primary storage-based snapshots of this volume after the migration has taken
place. That being the case, I don't think you should get back primary storage-based snapshots
from snapshotFactory.getSnapshots that are from different primary storages.

>    Affects Versions: 4.8.0
>         Environment: Xen Server
>            Reporter: subhash yedugundla
>            Priority: Major
>             Fix For: 4.8.1

> Issue Description
> ===============
> 1. Create an instance on the local storage on any host
> 2. Create a scheduled snapshot of the volume:
> 3. Wait until ACS created the snapshot. ACS is creating a snapshot on local storage and
is transferring this snapshot to secondary storage. But the latest snapshot on local storage
will stay there. This is as expected.
> 4. Migrate the instance to another XenServer host with ACS UI and Storage Live Migration
> 5. The Snapshot on the old host on local storage will not be cleaned up and is staying
on local storage. So local storage will fill up with unneeded snapshots.
