[DRBD-user] How to migrate from HDDs to SSDs?

[Daniel Ulman]

New approach on the same topic.

At the moment, I added a new SSD disk only in a single node (Because there is no VM running on the node)

It is possible to "delete" the pool associated (and its contents) to the HDD disk and recreate it with the same name on the new SSD disk?

What would be the correct steps to do that?


Regards,

Daniel

Hi everyone,

I have a proxmox cluster with 3 nodes and linstor on each node.

I want to change my old HDD disks to SSD.
The SSDs are a bit smaller than HDDs.
What is the correct procedure to migrate VM from HDDs to SSDs?

Regards,

Daniel
