I started off with what I thought was a powerful enough server. It's not. I have a new one built, but all of my drives are in my current array. They are all LUKS encrypted, even the cache drive. I want to move these drives to another hypervisor without losing any data. I think if I take note of which hard drive is assigned to sdc, sdd, sde, etc... and then make sure they go in the new server in the same order (scarry!), and then move the USB flash drive over... it might be good to go. That sounds dangerous, so I figured I'd ask if there is a better way, a safer way, an approved way, or a migration tool that I could use?

 

Thanks!

So the answer was NO, just figure it out. I used unbalance to remove 1 drive and let the array run on parity. That gave me enough space to start moving stuff from LUKS to the new server. Rinse and repeat. It was a pain in the ass. Next time I'll just buy more hard drives.
