I’m prepping a lot of stuff with cloud-init lately, and one step I always forget when installing my base OS is keeping the vg name clear of any hostname stuff.

So, as a reminder to myself, and a small howto for whoever else runs into this stuff:

  • Rename the VG: vgrename oldvgname newvgname
  • Modify /etc/fstab, change all entries that have oldvgname-<lvname> to newvgname-<lvname>
  • Edit /etc/initramfs-tools/conf.d/resume and change the RESUME= entry to match the new vgname
  • Update the initramfs: update-initramfs -u -k all
  • Update the grub install: update-grub

And reboot.
