A usage of 213M on / is not bad at all.. and you already have /var and /tmp as separate file systems.

yes, not so bad but I would prefer more, just a little :-)

Note: something odd here: / and /tmp is listed twice!?

Can't tell why, we had a energy lack in the middle of an upgrade/remove process, I did my best to recover the server integrity

I have access to the server room (not at the moment, but in the next days) so ASAP I will reboot and install a new kernel

To see where space is being used, try this:

du -x -m / | sort -nr | head -25

This should list the biggest directories first and give you an idea of
where space is being used. But since you do not have a separate
/home, I guess that this may account for some things...

# du -x -m / | sort -nr | head -25
