Hello everyone,

I have a couple of compute nodes that need HD upgrades. They are running VMs with Cinder volumes.

My question is this: Can I shutdown the VMs, rebuild the compute nodes, and then relaunch the VMs?

I am thinking “yes” because the volumes are not ephemeral but I am not sure.

Are there any VM specific data that I need to save from the compute nodes?

Thank you,

FV
