Debian/LVM increase disk size cheatsheet

Just a quick cheatsheet for increasing disk sizes for my TrueNAS scale VMs with debian os and lvm.

1. Make sure you created a snapshot!
2. Stop VM
3. Increase ZVOL
4. Start VM
5. lsblk => Check new size of /dev/sda
6. fdisk /dev/sda
   1. p (print)
   2. Copy partition row
   3. d (delete)
   4. n (new) -
   5. KEEP lvm signature!
   6. t (change type) => 30 for Linux LVM
   7. p (print again)
   8. Compare row (startbytes, size, type) with row from above
   9. w (write changes)
7. Reboot VM
8. pvresize /dev/sdaX (Replace X with actual number)
9. pvs => Check
10. lvs => Get VG and LV
11. lvresize -l +100%FREE /dev/<VG>/<LV>
12. resize2fs /dev/<VG>/<LV>
13. Reboot VM
