Hard Disk Space

Getting a message now saying the hard disk space is 76% full /dev/md2 how can i check whats going on, this server isnt used at the moment its just plugged in and being setup up for migration to.

No backups are running as they have not been configured and its not receiving any calls through it yet.

What is the capacity? 76% of 10G is not a surprise. 76% of 500g would be a thing

James

The drives are 60gb at the moment its at : using 41,115.44m of 54,995.21 83%

Since i posted nothing has been changed or a call made, i am slowly running out of space.

/dev/md2 using 41,115.44m of 54,995.21m (83%)

/dev/md0 using 31.36m of 290.45m (12%)

A handy command to run is du -sh * as it shows the size of CONTENTS of the subdirectories of the dir you are are in

As an example:

[[email protected] ~]# cd /var
[[email protected] var]# du -sh *
41M cache
8.0K db
8.0K empty
8.0K ftp
4.0K games
199M lib
4.0K local
16K lock
48M log
0 mail
4.0K nis
4.0K opt
4.0K preserve
192K run
200K spool
4.0K tmp
200M www
4.0K yp
[[email protected] var]#

If you wanted to be slightly smarter, you can turn off the ‘human’ readable format, and then sort by size:

[email protected] var]# du -s * | sort -n
0 mail
4 games
4 local
4 nis
4 opt
4 preserve
4 tmp
4 yp
8 db
8 empty
8 ftp
16 lock
192 run
200 spool
41720 cache
48880 log
203608 lib
204636 www
[[email protected] var]#

Thanks for that, will have to remember that command. Think i might have a slight problems with the log, also spool looks quite high also.

28M cache
8.0K db
8.0K empty
8.0K ftp
4.0K games
345M lib
4.0K local
16K lock
39G log
0 mail
4.0K nis
4.0K opt
4.0K preserve
172K run
2.1G spool
4.0K tmp
364M www
4.0K yp

Your log files are way too big, investigate why!

du -h --max-depth=1 /var/log

then (my guess)

ls -lsrS /Var/log/asterisk/

check the contents of the last few files (lines returned)

. . . .

Thanks for the commands, looks like fail2ban is logging alot this would be constant with my router, I have a draytek router that has been hit with a lot of DOS attacks in the last couple of months.

The most noticable thing is

43G /var/log/mysql

This is definitely “abnormal” to say the least, have you added anything to your my.cnf file ?, show us your:-

ls -lsrS /var/log/mysql

Not added anything to my.cnf file, only started noticing problems when i switch from the OSS endpoint manager to the commercial module, the server only has 3 extensions, 3 sip trunks and a sangoma a200 card but this isnt used at the moment as i cant get the disconnect supervision working properly for the UK.

[[email protected]lhost ~]# ls -lsrs /var/log/mysql
total 44324056
44324056 -rw-rw---- 1 mysql mysql 45387817267 Dec 13 22:31 mysql.log

Then you need to start logrotate ing your mysql logs (google how to do that)

but first, to reveal your ‘chattiness’ , please post the issue of:-

tail -50 /var/log/mysql/mysql.log

and for the hell of it

head -10 /var/log/mysql/mysql.log

This is what my.cnf looks like

[mysqld]
bind-address = 127.0.0.1
general_log = 1
general_log_file = /var/log/mysql/mysql.log
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql

Disabling symbolic-links is recommended to prevent assorted security risks

symbolic-links=0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

comment out the two lines starting with general_log or set up log rotation for that log.

If i comment out does that stop logging ?

Going to delete the log files manually, thought logrotate was an old problem that had gone away with newer distros

Your error logging will continue but your general logging will stop, there is little use for that but for debugging,

Your log file is 6 months long so you are not log rotating it by whatever method you installed/maintained mysql, I can’t comment on “distros” as I don’t use any.

Dicko Many Thanks

Been reading up http://wiki.freepbx.org/display/L1/Configure+Asterisk+log+file+retention

By default, FreePBX Distro is configured to keep a seven day history for most Asterisk log files.

So it looks like the distro is not taking care of the mysql logs.

Commented out the two lines in my.cnf starting with general.

Been reading up, might have to do some more reading before altering /etc/logrotate.d/asterisk

there is no reference to mysql.log does it need adding?

In linux you don’t regain disk space if you delete open files, this is why the /etc/logrotate.d/files are used for log files, either flush your mysql logs after dleteing them or turn mysql off before doing so, this is also at the root of why Centos can’t/won’t distribute mysql’s logrotate file, as I stated before you can have quite some fun on google with this one, don’t worry about the security issues you will turn up as your mysql server is running insecurely without a root password already.
