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.

MYSQLSERVERCLONE(1)						  MySQL Utilities					       MYSQLSERVERCLONE(1)

NAME
mysqlserverclone - Start a new instance of an existing MySQL server SYNOPSIS
mysqlserverclone [options] DESCRIPTION
This utility permits an administrator to clone an existing MySQL server instance to start a new server instance on the same host. The utility creates a new datadir (--new-data), and starts the server with a socket file. You can optionally add a password for the login user account on the new instance. OPTIONS
mysqlserverclone accepts the following command-line options: --help Display a help message and exit. --mysqld=<options> Additional options for mysqld. To specify multiple options, separate them by spaces. Use appropriate quoting as necessary. For exam- ple, to specify --log-bin=binlog and --general-log-file="my log file", use: --mysqld="--log-bin=binlog --general-log-file='my log file'" --new-data=<path_to_new_datadir> The full path name of the location of the data directory for the new server instance. If the directory does not exist, the utility will create it. --new-id=<server_id> The server_id value for the new server instance. The default is 2. --new-port=<port> The port number for the new server instance. The default is 3307. --quiet, -q Turn off all messages for quiet execution. --root-password=<password> The password for the root user of the new server instance. --server=<source> Connection information for the server to be cloned in <user>[:<passwd>]@<host>[:<port>][:<socket>] format. --verbose, -v Specify how much information to display. Use this option multiple times to increase the amount of information. For example, -v = verbose, -vv = more verbose, -vvv = debug. --version Display version information and exit. --write-command=<file_name>, -w<file_name> Path name of file in which to write the command used to launch the new server instance. EXAMPLES
The following command demonstrates how to create a new instance of a running server, set the root user password and enable binary logging: $ mkdir /source/test123 $ mysqlserverclone --server=root:pass@localhost --new-data=/Users/cbell/source/test123 --new-port=3310 --root-password=pass --mysqld=--log-bin=mysql-bin # Cloning the MySQL server running on localhost. # Creating new data directory... # Configuring new instance... # Locating mysql tools... # Setting up empty database and mysql tables... # Starting new instance of the server... # Testing connection to new instance... # Success! # Setting the root password... # ...done.
