I'd like to free up some SATA ports for ceph storage. So I'm thinking of moving my installation from a SATA RAID 1 to an NVME "disk". Is there a preferred method?
Easiest thing I can think of is to clone your current disk with Clonezilla to the new disk and make appropriate changes to the BIOS to boot from the new disk. It's a bit trickier if the NVME "disk" is smaller than current boot drive.
Oh that's very neat. It reminds be of FreeNAS's live boot disk additions and removals. That's probably what they use. Unfortunately, you still have to mess with BIOS settings to boot from new disks.
