I have two drives /dev/sda and /dev/sdb that are in a Volume Group with three volumes: /boot, /root, and /home, mounted respectfully.If I remove /dev/sda after doing# pvmove /dev/sda# vgreduce $myVolGroup /dev/sdaWill that affect my boot-loader assuming all of the /boot volume was on /dev/sda and it was the initial install disk?I would really like to avoid surprises.
Removing drive from LVM that has the /boot partition
boot;lvm
There are two components to the boot loader: the first stage, which is written directly to the MBR-and-later-blocks and isn't on a filesystem anywhere, and the second stage/config files/kernel image/initrd, which is in /boot. grub at least (I'm assuming that's your bootloader, if not this may not apply) knows about lvm in its own right, and so can find a /boot which uses it and load configuration from there. Thus, on that level it shouldn't make a difference. However, if you plan to remove /dev/sda from the system, you need to ensure that the first stage is in at least one of the remaining block devices; you would probably use some invocation of grub-install for this.
