Hi,

On my "new" Bullseye machines the root volume starts to fill up. The cause seems to be the /usr/lib folder. On my older Buster (10.13) machine the total /usr directory is 701M, the /usr/lib folder is 260M
In my /usr/lib folder on Buster is NO /usr/lib/modules folder

On my Bullseye machines the /usr/lib folder is 2+GB on the machines that have been operating for a while and 1+G on a machine that has been operating for a shorter while.

The cause seems to be the folder /usr/lib/modules#

Guessing on what I see these are libraries for older kernel versions. I usually clean up older kernel versions by using
# apt autoremove"
All 3 servers have 1 older kernel version installed according to apt autoremove.


Have you tried running also
apt autoclean
and
apt purge
?
