Mike, are you saying that XenCenter disagrees with xe? That doesn't seem right as they both get their info from the same API. Maybe XenCenter is looking at something subtly different.
XenCenter is open source (https://github.com/xenserver/xenadmin), so you can consult the source to see what it's reporting. Or send a screenshot of what you're looking at and I can find the correct bit of source. -- Stephen Turner -----Original Message----- From: Mike Tutkowski [mailto:mike.tutkow...@solidfire.com] Sent: 04 November 2014 17:28 To: dev@cloudstack.apache.org; Edison Su Subject: Creating a backup of a hypervisor snapshot Hi, The standard behavior when we take a snapshot of a volume on XenServer is to take a hypervisor snapshot of the volume and then copy this snapshot to secondary storage. We then try to delete all other hypervisor snapshots for this volume. I notice the process of deleting all other hypervisor snapshots for this volume never finds any snapshots to delete and our list of hypervisor snapshots continues to grow over time for the volume in question. (Below) Set<VDI> snapshots = volume.getSnapshots(conn); returns the empty set, so there's nothing to delete. However, if I look in XenCenter, I can see hypervisor snapshots for the volume in question. It appears we are passing in the correct info to this method, too. When I use xe, it confirms that the VDI that represents our volume does not have any snapshots, which seems odds. protected boolean destroySnapshotOnPrimaryStorageExceptThis(Connection conn, String volumeUuid, String avoidSnapshotUuid) { try { VDI volume = getVDIbyUuid(conn, volumeUuid); if (volume == null) { throw new InternalErrorException("Could not destroy snapshot on volume " + volumeUuid + " due to can not find it"); } Set<VDI> snapshots = volume.getSnapshots(conn); for (VDI snapshot : snapshots) { try { if (!snapshot.getUuid(conn).equals(avoidSnapshotUuid)) { snapshot.destroy(conn); } } catch (Exception e) { String msg = "Destroying snapshot: " + snapshot + " on primary storage failed due to " + e.toString(); s_logger.warn(msg, e); } } s_logger.debug("Successfully destroyed snapshot on volume: " + volumeUuid + " execept this current snapshot " + avoidSnapshotUuid); return true; } catch (XenAPIException e) { String msg = "Destroying snapshot on volume: " + volumeUuid + " execept this current snapshot " + avoidSnapshotUuid + " failed due to " + e.toString(); s_logger.error(msg, e); } catch (Exception e) { String msg = "Destroying snapshot on volume: " + volumeUuid + " execept this current snapshot " + avoidSnapshotUuid + " failed due to " + e.toString(); s_logger.warn(msg, e); } return false; } -- *Mike Tutkowski* *Senior CloudStack Developer, SolidFire Inc.* e: mike.tutkow...@solidfire.com o: 303.746.7302 Advancing the way the world uses the cloud <http://solidfire.com/solution/overview/?video=play>*™*
