Yep - exactly. In fact, all of the snapshot strategies are loaded when the
server starts. I forget what the interface looks like, exactly, but there
are methods that let you respond to whether you can handle all different
kinds of operations on a volume.

I assume CloudStack allows for multiple snapshot strategies to be loaded at
the same time? That way different vendors can provide their own unique ones
and handle their own volumes (if the default strategy isn't desired).

Thanks, Chris
So, ideally, I would write a snapshot strategy and interrogate in the
incoming volume, make sure it's one of mine, then return that I can handle
reverting.
If it's not one of mine, I can run the default logic that's provided from
the class my strategy extends.
Sounds about right?
Hey Mike - I can provide a bit of background here. When working on my
snapshot strategy, we knew that reverting single volumes was possible, but
recognized that it may not be for all storage vendors or hypervisors (since
hypervisors essentially have their own snapshot strategy). Additionally,
some
For those who are interested in this, it appears you have to write a
SnapshotStrategy implementation and override the canHandle method (this is
the default implementation, which is provided by the
XenserverSnapshotStrategy class):
@Override
public StrategyPriority canHandle(Snapshot snaps
Actually, it looks like you can revert a volume to a snapshot, if the
underlying storage supports such an operation.
I hadn't been explicitly setting this "revertable" field and it appears to
default to "false" and the GUI then doesn't show the button.

Hi,
Under the Storage tab in the GUI, we can take a snapshot of a volume
(assuming the underlying storage plug-in supports that operation).
When I examine the options of the created snapshots, I see the snapshot can
be deleted (as you'd expect), but I don't see a "revert volume to snapshot"
