Now I would need to figure out how to boot to the CentOS installation on server A/sdb and I would like to ask about a few details:
- I am confused about the logical volume names: which ones should I use
on
the new server's fstab, the old ones (rsynced from server B/sda) or the ones I used when creating the logical volumes from server A? If I need to use the new ones, should I update the names also somewhere else than
fstab?
Yes, you need to use the new LVM device names in the /etc/fstab.
I started wondering, where are the device names stored? As I created them from the A/sda system I started thinking that perhaps they were written somewhere into the A/sda system and if I boot to A/sdb system they are no longer valid...
- As the new installation will boot from sdb instead of sda, do I need to
update this information somewhere (like /boot/grub/device.map) ?
It depends are you going to remove 'sda' from the server. In which case your sdb will become the sda. You will need to install grub on this disk.
For now, I would like to keep both systems. At some point I might need to boot the A/sdb system in a totally new machine (in which case the system will be sda again...).
