Subject [jira] [Commented] (CLOUDSTACK-5863) Restore volume snapshot
Date Tue, 01 Sep 2015 15:01:47 GMT


ASF subversion and git services commented on CLOUDSTACK-5863:

Commit c0a0aec0f9041a3577d96d69260c7aa33482199d in cloudstack's branch refs/heads/master from
Wei Zhou
[;h=c0a0aec ]

Merge pull request #732 from ustcweizhou/revert-volume-snapshot-master

Guys, can you review it? things need to be discussed:
(1) this supports KVM/QCOW2 only. Anyone want to implement for other Hypervisor/format ?
(2) The original data volume (on primary storage) will be removed.
(3) The script uses the default timeout in libvirtComputingResource. Do we need to add one
in global configuration (like copy.volume.wait or backup.snapshot.wait, create.volume.from.snapshot.wait)
(4) In scripts/storage/qcow2/, I use "qemu-img convert -f qcow2 -O qcow2"
to copy the snapshot from secondary to primary (hence there is no base image file), instead
of "cp -f", this is because convert is faster than cp in my testing.

* pr/732:
  CLOUDSTACK-5863: revert volume snapshot for KVM/QCOW2
