v !!! POST-MIGRATION EDIT !!! v

I shrunk the LVM partition by 5000 MiB and just ran dd overnight. I had to shuffle my boot-order around a bunch to find the one partition that would boot properly but it all just works.

v !!! ORIGINAL POST !!! v

Hi! My Proxmox machine has 3 disks (see pic). I wish to migrate sdc to a 2TB SSD. I have LXCs on all drives and I would really like to avoid having to restart from backups. I don’t have any special configuration on my proxmox, it’s pretty clean and basic.

Is it safe to simply dd the old disk to the new one? I can’t find an explicit answer to this question that doesn’t also have a lot of other variables not relevant to me.

If not, what else can I do?

Yeah, you can do that as well. Just mentioning that DD isn’t the simplest way to achieve what you want.

It might not be, but I am intimately familiar with it. It’s proxmox itself that’s the wildcard here. I will shrink the LVM and then DD it to the new disk.
