running out of space

[mihaib]

Hi all
I am new to proxmox. I installed 8.2.7 on a 32GB M2.
I recently saw that I am running out of space because of /dev/mapper/pve-root
root@Bespin:~# df -h
Filesystem Size Used Avail Use% Mounted on
udev 55G 0 55G 0% /dev
tmpfs 11G 4.6M 11G 1% /run
/dev/mapper/pve-root 13G 12G 456M 97% /
tmpfs 55G 34M 55G 1% /dev/shm

//172.16.10.4/backup 19T 95M 19T 1% /mnt/pve/backup
tmpfs 11G 0 11G 0% /run/user/0


also :
root@Bespin:/dev/mapper# pwd
/dev/mapper
root@Bespin:/dev/mapper# ls -la pve-root
lrwxrwxrwx 1 root root 7 Oct 15 03:29 pve-root -> ../dm-1
root@Bespin:/dev/mapper#

it is interesting as I keep my templates on Images and the VMs/CTs on Apps.
can you please guide me here on what to do to free up this space?

thank you

Have you ever cleaned up Root?

Cleanup apt cache:

apt clean

Cleanup packages no longer used:

apt autoreove --purge

After please post your content of /boot/grub

And please also the output of

pvs
vgs
lvs

thanks for your reply.

I see you have mounted remote storage on /mnt/pve/backup & /mnt/pve/media

You may have written/backup to that mounted location when the remote storage wasn't in fact available. It will then get written locally.

To check, have a look at the above mountpoint locations - when the remote storage is offline. You may find "unwanted" content there.

Logs (/var/log) or default local pve storage (/var/lib/vz) might also be the culprit. Check directories under /var du -shx /var/*

var is clean. I had 8gb of dump stuff I moved away. looks good now.
thank you folks. appreciate your help

If manual mount points for storages exist, is_mountpoint prevents data from being written accidentally. Here is an example: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_configuration_12
