Expand Proxmox Filesystem

[Jay L]

Hi,

I have proxmox running on a system and it is working well. I just reviewed the GUI in Proxmox and noticed that it states 29GB in total in the system. However, the server actually has about 128GB of disk space and so it seems to be missing 100GB. I am trying to figure out how to expand the Proxmox FS to include all of this. Below is some relevant output.

Can anyone advise on how to expand the volume? Ideally, I would be able to do this non-disruptively.

you ARE using the whole disk, just not mapped to any mounted filesystem. see all those logical volumes named pve-vm-***-disk-1? those are using the available space on your disk.

you can always expand/add space to an existing mounted filesystem (http://tldp.org/HOWTO/LVM-HOWTO/) but that will take away from space available to virtual disks.

Hi,

Thank you. I get it now. It seems like this was a rookie error. Sorry about that. I appreciate your help.

As an addition, the page linked below was helpful. I mistakenly focused on the capacity of the "HD Space(root)" as illustrated in the GUI. This is the space used by Proxomox OS and is separate from VM storage which lives in the "Data" directory.
