resizing proxmox partition

[daddy_fatsacks]

Hello All,

I had installed PVE onto a 64GB leaving 8GB for a zil disk. I no longer wish to have this 8GB allocated as I see zil as something which I will never use.

My current partition scheme looks like this :


NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 59.6G 0 disk
├─sda1 8:1 0 1M 0 part
├─sda2 8:2 0 256M 0 part
├─sda3 8:3 0 51.4G 0 part
│ ├─pve-swap 253:0 0 20G 0 lvm [SWAP]
│ ├─pve-root 253:1 0 14.8G 0 lvm /
│ ├─pve-data_tmeta 253:2 0 1G 0 lvm
│ │ └─pve-data-tpool 253:4 0 9G 0 lvm
│ │ └─pve-data 253:5 0 9G 0 lvm
│ └─pve-data_tdata 253:3 0 9G 0 lvm
│ └─pve-data-tpool 253:4 0 9G 0 lvm
│ └─pve-data 253:5 0 9G 0 lvm
└─sda4 8:4 0 8G 0 part


sda4 is the space that I would like to reclaim back, into sda3 to increase one of the logical volumes there.

could someone guide me on how to do this?

sda4 is the space that I would like to reclaim back, into sda3 to increase one of the logical volumes there.

Note: if you make a mistake during the following process you system may not boot any more - strongly recommended: to backup your disk first!

* Remove part4
* Remove part3 and create it again, starting at the same point as before but occupying the disk until the end
* Resize pv /dev/sda3
* You can now define a new lv or extend one of the existing ones.
