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!
