expanding lvm-thin pool

[ggrey]

hi, i'm fairly new to proxmox and getting on with it. i've first installed in on a 240gb ssd and then cloned on a 500gb ssd drive as i've had it available.

now despite using the gparted to expand the partition, in proxmox the pve-data-pool still shows at 149gb, but the disk sdb3 shows the full 464gb. how do i go about expaning it to take the full drive? Thought it would be done on the flight, as previously i've installed on a 120gb and easily migrated/cloned it on the 240gb it is on now.

You could install webmin (runs on port 10000) or WeLees for more GUI control over your LVM, but make sure all VM/LXC are backed up before messing around with resizing.

I do not recommend messing around with commandline LVM resizing unless A) you've done it before, and B) you know exactly what you're doing and why.

For utility purposes I would recommend making a standalone "portable PVE" on e.g. external SSD or SD card with everything you need to troubleshoot, then you won't have to deal with open files and working on a live mounted partition/filesystem.

Thanks, will look into this
