OK, I've got a Debian computer where the system disk is showing signs of
flakiness. I want to replace it with a new disk and retire the old one.
Before I do it for real, I'm doing a dry-run on a vmware virtual machine. I
don't *think* the fact that it's virtual should affect my results. But I put
it out there, just incase.
Here's what I've done so far:
*) Set up a VM with one virtual SATA disc drive, and installed Buster on it.
The system has a MBR partitioning with /boot in /dev/sda1 and the rest of the
disk as an LVM volume-group ("tryout-vg") partition in /dev/sda5 with root,
swap, and home as LVs.
*) Added a virtual SATA disk drive and partitioned it the same as above --
/dev/sdb1 is boot and /dev/sdb5 is the LVM partition. However, in order to
have both disks available for mounting (see below) at the same time, the new
drive's LVM volume-group had to have a different name ("new-vg").
*) Used rsync to copy the contents of the boot, root, and home partitions from
the original disk to the new one.
*) Modified the /etc/fstab on the new disk to reflect the names and uuid's of
the partitions on the new disk.
*) Booted the Buster install DVD in rescue mode and ran "reinstall boot loader"
for the new disk.
*) Rebooted and told the BIOS to boot from the new disk. It went to the grub
screen and proceeded to boot.
*) To my surprise, after it booted, I logged in and saw that the root, swap,
home and boot partitions that were mounted were all from the original disk!
So what am I missing? How do I tell grub on the new disk to use the root
partition and volume-group on the new disk?
Thanks for any help!
Rick
