Why do you have huge 5 year old database dump files on your server?

These are from 2014, but this is 2019 brother.

Based on this observation, it is logical to conclude that your system is not properly administered if your server is having disk space problems and you have huge database dumps and other backup file on the same server / disks.

If you want to "reclaim disk space" find all these huge database dump files and backup files and move them off this server; or to a "data archive disk" with space for these types of files.

Cheers and Regards,

Thank you for your suggestions, based on which I've removed 320 Mb worth of .sql files to /mnt/backup from /root :
this is size of my root now:
408688 /root

I really thought that would allow MySQL to start, but no, I am still getting
Code:
190826 23:08:42  InnoDB: Started; log sequence number 0 8747645
190826 23:08:42 [ERROR] /usr/libexec/mysqld: Error writing file '/var/run/mysqld/mysqld.pid' (Errcode: 28)
190826 23:08:42 [ERROR] Can't start server: can't create PID file: No space left on device

, even after truncating existing 50Mb MySQL log file:
truncate -s 0 /var/log/mysqld.log

I think I misunderstood your question. I thought it was referring to automatically releasing space after deleting log files, but apparently you meant just active log files. Absolutely, the log files are crucial.
And yes - nobody is managing this server - I am a C#/SQL software developer, trying to get the company's CRM Linux server back online.
