I really need to mount RW in both VMs. I am creating a fail-over
cluster, using concurrent storage for data.
I'll try to create a new vbd and attach it to the other VM.
Any other clues?
I'm not sure exactly what you want to do. Are you proposing to plug a
single VDI read-writeable in two running VMs, at the same time? Or do
you want to only plug the VDI into two VMs, and only turn the second VM
on once the first one fails? The second proposal is fine, but the first
one will likely lead to data corruption.
If you want a solution that's more like the first proposal, then you
might want to look at setting up DRBD (http://www.drbd.org/) within the
guest VMs. XCP doesn't have support for using DRBD as a storage
repository directly, but if you set it up in the guests themselves, you
might be able to solve your problem.
