---------------------------------------------
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.
