Subject [jira] [Commented] (CLOUDSTACK-7300) Cannot create Snapshot on KVM
Date Fri, 15 Aug 2014 13:19:18 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-7300?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14098532#comment-14098532
] 

Wei Zhou commented on CLOUDSTACK-7300:
--------------------------------------

Sorry What I said is not very clear.
cloudstack use "qemu-img -s" to save the volume snapshot to a qcow2 file, and store in secondary
storage.

Your QEMU version is too old to support "qemu-img -s", so cloudstack can not save the snapshot
to a qcow2 file.

> 1. Creating a Snapshot says successful.
> 2. When viewing the actual Snapshot, it shows "Error" status.
> 3. Management Server Logs the error below.
> 4. It seems the Snapshot is attempting to be copied to a path that is not mounted (Sec
Storage Snapshots).
> 5. Have restarted Agent, SSVM, and management server. Has not corrected.
