> Set up:
> Advanced Zone with 2 Xenserver 6.2 hosts:
> Steps to reproduce the problem:
> 1. Deploy 5 Vms in each of the hosts with 10 GB ROOT volume size , so we start with 10
Vms.
> 2. Start concurrent hourly snapshots for ROOT volumes of all the Vms.
> 3. Shutdown the Secondary storage server when the snapshots are in the progress.
> 4. Bring the Secondary storage server up after 1and 1/2 hour.
> After the secondary store was brought up , we see the snapshot process continue to be
active ( I see the copy command that was halted when the secondary store was down , starts
progressing when server is drought up online).
> I also see that the snapshot process has been completed on the secondary store. But management
server throws the following exception and leaves behind the snapshot in "CreatedOnPrimary"
state in DB.
