Resize OS LVM

[mcdowellster]

Hello all,

I made a huge mistake when I installed my proxmox storage (ceph) node. I installed the OS on those terrible slow Dell dual SD card devices. The limited size (16gb) left the OS and swap pretty tiny. I have cloned that install into two 120GB SSDs. Performance is way better and IO delay is way down.

Done loads of reading on the tropic but I want some advice. I want to now increase the swap partition and the LVM partition to match the much larger (faster) OS storage. I would prefer not to use a live CD but to run some cli commands while the OS is running. First is it possible? If so, what is the process?

Second is this risky?

Thanks guys!

Regarding OS LVM, see e.g. https://linuxtechlab.com/beginners-guide-resizing-lvm/

Regarding swap:
- disable swap by

swapoff

- increase swap lvm be

lvextend

- enable swap by

swapon
