as you can see here:
Filesystem Size Used Avail Use% Mounted on udev 10M 0 10M 0% /dev tmpfs 13G 332K 13G 1% /run /dev/sda1 20G 19G 747M 97% / tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 26G 13M 26G 1% /run/shm /dev/mapper/pve-data 533G 380G 127G 75% /var/lib/vz
my main partition /dev/sda1 is completly full, 747M free only. But I'm not able to determine where are those few gigas a I had free a few month ago.
my log directory is not the problem, less than 2 gigas. I tried to make du folder by folder in the / without the /var/lib/vz, but still, I can't see what's taking so much size.
Is there a anyway to make something like this du /dev/sda1/* -hs ? obsiously it didn't work for me, but that what I would like to know.
I did also that
du -csh / --exclude=/var/lib/vz --exclude=/mnt
and the results is
2.5G / 2.5G total
Best regards and thanks for your help.
