I have a volume group made from 3 partitions on 2 different physical disks. One of the disks is failing. I have a new disk connected via USB; it is large but a bit slow (5400RPM, though the USB might be temporary). It is large enough to hold the entire contents of the existing VG. I am looking for suggestions about how to approach this. The pvmove command looks promising, but the docs warn that things are in a delicate state during the migration (and advise backups). Since it seems almost certain there will be I/O errors on the old drive, I'm not sure if pvmove is a good idea. Is it? Alternately, I could do a file system level rsync, but I would probably need to boot into an alternate system for the last step and there are quite a few LVs. Would any kind of RAID/mirroring be an option? My impression is I need to set that up on initial creation of the VG. BTW, any advice on partitioning the new drive? I know I could just use the whole physical device, but I'm concerned that if I want to boot using the disk, or install another (non-Linux) OS that I'll need more traditional partitions on the drive. My first cut was to create a GPT partitioning scheme with a 1G blank paritition and partition 2 holding the rest of the 2TB for LVM. Linux is my primary OS. Thanks.
