Disk size different between proxmox and vm

[spleenftw]

Hello folks,

I got this VM :


So the disk size should be 128gig.

But when i run a df -h on the vm, this is what i'm seeing :

df -h Filesystem Size Used Avail Use% Mounted on udev 969M 0 969M 0% /dev tmpfs 198M 936K 197M 1% /run /dev/sda1 62G 37G 22G 63% / tmpfs 986M 0 986M 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 198M 0 198M 0% /run/user/1001

So i wonder where the other 64gig are ?

Hello, could you please send us the VM configuration? This is at `/etc/pve/qemu-server/VM_ID.conf`, could you please also send us the output of `lsblk` from inside the VM?

lsblk says that you indeed have a 128G drive, but the root partition only has assigned 64G. Since you have two partitions after the root partition expanding the partition might prove to be difficult. It might prove easier to make backups and start anew.

is there a way to easily shrink the 128G drive to 64 ?

 

[Maximiliano]

There are ways, but it is a rather tricky operation. If you decide to try either to shrink the disk or expand the partition make sure you do a backup first.

i did an lvm lvreduce -L -64g /dev/pve/vm-450-disk-0 and then a qm rescan but there's still 128gig attached if i'm doing a lsblk, even though proxmox is showing 64gig

My guess would be you are running portainer on ubuntu? Because the Ubuntu installer won't use the whole disk by default unless you tell it to do so.

i think it was a 64gig disk base. Then i added 64gig one day without really using it. So i just shrunked it back to 64gig, every thing is still working perfectly.
