Revert Snapshot question
Hi
I have a question on a new feature that I've noticed since upgrading to AC 4.6.2 - the Revert to Snapshot option. This option is available on a very small number of snapshots which I have. The rest of the snapshots do not have this option/button in the GUI. Could someone one tell me what is required to have this feature enabled on a snapshot?
I am using KVM + RBD + NFS as the secondary storage.
Many thanks
Andrei

Wido,
I've figured out why some RBD snapshots was showing the Revert to snapshot icon and others didn't. The issue seem to relate the old bug in acs, which seems hasn't been resolved or not fully resolved. Some of the created volumes are showing as QCOW2 type whereas the majority are RAW. This applies to VMs which were recently created on acs 4.5.2 and prior versions.
After changing DB values, the Revert to snapshot icon is no longer there.

I don't think RBD can be reverted right now, that has not been
implemented in the current KVM code.

Andrei,
The mailing list strips the attachments, just upload them somewhere on the web.
If you think this is a bug, perhaps open an issue and also email dev@.

Hi Wido,
Here is what i've got (screenshot attached). This button is not visible on all snapshots, but rather just a few snapshots. As far as I can tell there is no difference between how the snapshots are taken and all snapshots that I have are taken from RBD volumes.
Do you know if the RBD snapshots have the capability to be reverted to volumes without having to go through the process of creating the template and the new vm? Or is this feature not available for RBD snapshots and what I am seeing is likely to be a small GUI bug?
Many thanks
Andrei

I don't know where the button comes from. My main expertise is RBD and
the inside of the KVM hypervisor. What the management server does with
the different strategies, I don't know.

Hi Lucian,
I have no none RBD volumes, yet some snapshots give me the button to do Revert and others don't. There is no difference between the snapshots as far as I can tell.
Wido, could you please confirm?

Hello Andrei,
This was discussed/implemented in https://issues.apache.org/jira/browse/CLOUDSTACK-5863
As far as I know this is a qcow2 only thing, though I see Wido chipping in as well, though it's not clear if RBD is supported just as well (cc-ing Wido).
