Live Migration Questions

[rocky3598]

I have a master proxmox node setup with a raid card in it. The raid card is set as shared storage. The second node has its virtual machines running off of the shared raid card. If I want to do a hardware upgrade on the master node is it possible to move those to the slave node?

More so the question is does live migration copy over the virtual machine or is it always stored on the same one just can be accessed by the other?

If so would it be better to store VM's on a external datastore?

Thanks for the help in advance.

In the past I've used a backup and restore because it is the mistake proof way.

There is no live migration of running VMs on share storage that I know of. This can be done on containers however.

It would depend on where you mount your container storage of course.

Hopefully this is helpful, I'd be happy to clarify steps if it helps at all.

I should clarify, you can do live migration of the VM (depending on file type, e.g. vmdk, qcow2, etc) however this does not move the storage location with a VM.

Shared storage, in terms of best practices, is a storage location that is not also running a VM Host node for this reason.
