Hi.
I was wondering what would be correct way to migrate system VMs
(storage,console,VR) from local storage to CEPH.
I'm on CS 4.2.1 and will be soon updating to 4.3...
Is it enough to just change global setting system.vm.use.local.storage =
true, to FALSE, and then destroy system VMs (cloudstack will recreate
them in 1-2 minutes)
Yes, that would be sufficient. CloudStack will then deploy the SSVMs on
your RBD storage.
Also how to make sure that system VMs will NOT end up on NFS storage ?
Make use of the tagging. Tag the RBD pools with 'rbd' and change the
Service Offering for the SSVMs where they require 'rbd' as a storage tag.
Thanks for any input...
