I have a situation where there is ~300G available on /dev/sda and I want to extend a partition /dev/sda3 with the additional ~300G.
However from what I read online if /dev/sda4 exists, I cannot increase /dev/sda3 unless I remove /dev/sda4 which contains /boot/efi (which I don't believe is an option).
fdisk -l /dev/sda
Disk /dev/sda: 644.2 GB, 644245094400 bytes, 1258291200 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sda1 * 1 629145599 314572799+ ee GPT
What is also interesting is that the "Disk label type" is dos when I think it is GPT. This seems to be preventing it from showing /dev/sda2, /dev/sda3, and /dev/sda4 when running fdisk -l. I do not have gparted on this system.
I know these partition exist because it can be seen in df -h:
df -h

/dev/mapper/vg-var_log_audit 2.0G 65M 2.0G 4% /var/log/audit
/dev/sda3 is using lvm on it and that will allow me to extend the /dev/mappers once I have the additional 300gb on the PV.
I see the free space from the parted command:
parted /dev/sda unit MiB print free

My Question: Is there anyway I can increase the pv /dev/sda3 without removing /dev/sda4 so that I can increase the vg's that exist on /dev/sda3 with that additional 300gb?
