missing ~20 GB of the 32GB usb stick

[FuriousRage]

I installed PVE on a 32GB stick.
but pve root is barely 10GB

I do have 2 storages i disabled:
local directory VZDump backup file
local-lvm LVM-thin disk image, container

Because i wanna use the raided nvme for CT containers and my /srv for mass storage as default options, and the local* was always the default.

I have run that lvextend, but still missing like 20 GB, and my pve / is at around 10GB/12GB
Datacenter -> pve -> Summary:
/ HD space 78.20% (9.58 GiB of 12.25 GiB)


So how to get back the missing(?) 20 or so GB?

Hi,

Proxmox (logs and configs (/etc/pve) will kill any usb device within months …. Use at least a external spinning hdd or a servergrade ssd (consumer will also wearout fast but not that fast as a usb stick).

Otherwise proxmox installed a LVM and did not use the full available space but also created a LVM-thin volume. You could delete this lvm thin volume and resize the lvm pve root volume … but again I really recommend you not to use a usb stick!

So long

IDK what you're on about, df clearly shows root is 13GB not 10. You have ~9.6GB used with some free space left over still.

However, you really really don't want to try and run Proxmox 24/7 from a usb stick. It's fine for a recovery environment that doesn't see a lot of use, but there is a lot of writing involved. (There are things you can do to mitigate this, log2ram + zram -- but it's not esxi or *NAS)

Do yourself a huge favor - Reinstall to external SSD (preferably at least 256-512GB) and turn off cluster services and atime everywhere (including in-guest) to save on writes.

To fix your missing root free space easily with a GUI, install webmin (runs on port 10000), login with browser, and use the LVM module. It's literally a 1-button click to tell root to expand and use the remaining slack LVM space. No reboot or terminal command needed. There is also WeLees Visual LVM which comes in handy, but the webserver for it uses 100% CPU and I end up sending it a kill -SIGSTOP / SIGCONT when I need it.

You can still use the existing usb stick for an emergency / recovery environment, it will have proper ZFS and LVM support + whatever utilities as mentioned above

But when you reinstall, go thru the Advanced options when you see the ext4 and make sure you allocate things properly. You also have the option to install to ZFS and bypass LVM entirely, with the option to create a separate lvm-thin in the future.

Also - remember that it's important to have backups. Setup Proxmox Backup Server on separate hardware and take advantage of dedup.
