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

[Daniel Ulman]

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
