How to fix the error - The partition with /var/lib/mysql?

Question

MySQL

I use Zabbix 2.2
MySQL database filled the entire disk with itself, most of all it takes history.
On restart or next start it gives
Error: The partition with /var/lib/mysql
df -h
rootfs 129G 123G 0 100% /
udev 10M 0 10M 0% /dev

I also looked through the winscp folder properties, they take up a lot of space.

Answer 1

Check if the mysql logs take up a lot of space. Then you can beat the oldest ones.

Answer 2

I checked, it's not in the logs, they are 7 megabytes each and there are 7 of them in total ...)

Answer 3

Connect another HDD, transfer /var/lib/mysql to it and mount to this path
