/etc/init.d/mysql: ERROR: The partition with /var/lib/mysql is too full!

How to repeat:
sudo /etc/init.d/mysql start

Could you try running:
LC_ALL=C BLOCKSIZE= df --portability $datadir/. | tail -n 1 

This is the command the init script runs to check for minimum available space (4MB)

I have the same problem.

Did you set the datadir variable before running the command?

Try replacing $datadir with /var/lib/mysql
[21 Jun 2016 9:19] Stéphane Lambert
it is. 

Please note I just run an upgrade and the server was perfectly well for years...

Can you try running:
/usr/sbin/mysqld --print-defaults | tr " " "\n" | grep -- "--datadir" 

And see what the output is?
[21 Jun 2016 9:51] Stéphane Lambert
/usr/sbin/mysqld --print-defaults | tr " " "\n" | grep -- "--datadir" 


[21 Jun 2016 10:00] Stéphane Lambert
Can it be linked to something around ubuntu's open-files-limit ?
[21 Jun 2016 10:04] Lars Tangvald
Can you add
 set -x
to the start of /etc/init.d/mysql

Then try to start up the server again?
Should print out more data from the startup.
[21 Jun 2016 10:22] Lars Tangvald
Just noticed that if you run /etc/init.d/mysql as a regular user (not mysql or root) it will trigger this exact error.

Are you starting the service as non-root? If so, try just adding a sudo
[21 Jun 2016 10:31] Stéphane Lambert
/etc/init.d/mysql  start set -x


df: '/var/lib/mysql/.': Permission denied
 * /etc/init.d/mysql: ERROR: The partition with /var/lib/mysql is too full!


sudo /etc/init.d/mysql  start set -x
[sudo] password for slambert: 


 * Starting MySQL database server mysqld                                                                                                         No directory, logging in with HOME=/
[21 Jun 2016 10:55] Lars Tangvald
If you just run 
sudo /etc/init.d/mysql start

The server won't be started? Or does it give the error, but still start.

Which distro version are you running on?
[21 Jun 2016 10:55] Lars Tangvald
And just to note: The service must be started with sudo
[21 Jun 2016 12:15] Stéphane Lambert
No it doesn't ; 
sudo /etc/init.d/mysql  start set -x
[sudo] password for slambert: 


 * Starting MySQL database server mysqld
No directory, logging in with HOME=/

I'm under 
Distributor ID:	LinuxMint
Description:	Linux Mint 17.2 Rafaela
Release:	17.2
Codename:	rafaela
slambert@smongdee02 ~ $ 

Thanks for your help, it's big headache hear...
[21 Jun 2016 12:29] Lars Tangvald
It still fails without set -x?

Can you check if there's anything in mysql error logs?

Also, can you check the output from 
 getent passwd mysql
[21 Jun 2016 12:39] Stéphane Lambert
Start without set -x gives same result

I have 2 errors in logs :
[ERROR] Can't open the mysql.plugin table. Please run mysql_upgrade to create it.
[ERROR] Fatal error: Can't open and lock privilege tables: Incorrect file format 'user'

getent passwd mysql
mysql:x:115:125:MySQL Server,,,:/var/lib/mysql/:/bin/false
[22 Jun 2016 6:14] Lars Tangvald
You upgraded from a previous 5.5 to a newer 5.5?

Can you try running:
 mysqld --verbose --help 2>&1 >/dev/null
and see if there's any output? It should print out any errors that are preventing the server from starting
[22 Jun 2016 6:16] Lars Tangvald
You probably need to run that as sudo as well
[22 Jun 2016 8:37] Stéphane Lambert
I upgraded the whole system a few days ago. Then I made a reboot. The mysql server died that day.

Sorry, I couldn't wait more, so I purged mysql and reinstalled everything. 

Thanks for your help anyway. I hope this will not happen to too many people.

Cheers :)
[22 Jun 2016 8:46] Lars Tangvald
No problem. Sorry we couldn't be of more help.
