Subject [jira] [Created] (CLOUDSTACK-10222) Snaphosts remain on primary storage
Date Tue, 09 Jan 2018 17:09:00 GMT
Khosrow Moossavi created CLOUDSTACK-10222:
---------------------------------------------

             Summary: Snaphosts remain on primary storage
                 Key: CLOUDSTACK-10222
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10222
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Secondary Storage, Snapshot, XenServer
    Affects Versions: 4.10.0.0
         Environment: XenServer, Swift
            Reporter: Khosrow Moossavi
             Fix For: 4.11.0.0


When user creates a snapshot (manual or recurring), snapshot remains on the primary storage,
even if the snapshot is transferred successfully to secondary storage. This is causing issues
because XenServer can only hold a limited number of snapshots in its VDI chain, preventing
the user from creating new snapshots after some time, when too many old snapshots are present
on the primary storage. 
{code:java}
reason: SR_BACKEND_FAILURE_109 The snapshot chain is too long
{code}


Proposed solution:
Keep only one snapshot (last successful) on the primary storage regardless that it was a full
or partial snapshot.
