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 Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg-root 10G 5.4G 4.7G 54% / devtmpfs 24G 0 24G 0% /dev tmpfs 24G 39M 24G 1% /dev/shm tmpfs 24G 209M 24G 1% /run tmpfs 24G 0 24G 0% /sys/fs/cgroup /dev/sda2 509M 124M 386M 25% /boot /dev/sda4 200M 5.1M 195M 3% /boot/efi /dev/mapper/vg-tmp 8.0G 33M 8.0G 1% /tmp /dev/mapper/vg-var 3.0G 268M 2.8G 9% /var /dev/mapper/vg-home 509M 28M 482M 6% /home /dev/mapper/vg-var_log 5.0G 215M 4.8G 5% /var/log /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 Model: VMware Virtual disk (scsi) Disk /dev/sda: 614400MiB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: pmbr_boot Number Start End Size File system Name Flags 0.02MiB 1.00MiB 0.98MiB Free Space 1 1.00MiB 2.00MiB 1.00MiB bios_grub 2 2.00MiB 514MiB 512MiB xfs 3 514MiB 306999MiB 306485MiB lvm 4 306999MiB 307199MiB 200MiB fat16 307199MiB 614400MiB 307201MiB Free Space
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?
