I'm having issues with the / partition getting too full. More specifically what can't I delete from /tmp. Here is some helpful info ( I hope ) .

The drive space left (not much eh)

Code:
 sh-3.1$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda1             4.7G  4.2G  259M  95% /
/dev/hda3             144G  132G   12G  92% /myth
tmpfs                 188M  4.0K  188M   1% /dev/shm


and here is what is in the /tmp folder
Code:
sh-3.1$ dir

Tell me the size of the log files in /var/log/mythtv. That frontend log can sure get big fast!

whats a good way to shrink it? i presume deleting the file is bad... deleting it's contents?

Hi,

What version are you running? R5C7 needed a tweak to stop a log issue.

I zero out a file with: echo "" > /path/to/filename use with caution.

Sorry that I disappeared on this post got busy at work and life and such.
I'm using version R5E50.
I'm not at home right now so I can't give you the size of the /var/log/mythtv folder I'll look at it when I get home how big should it be?
What does echo ""> /path.etc do and how should I use it?

So my real question is are the files in the /tmp folder really temporary?
and can all of those ssh- "random text" be deleted
Thanks everyone.

Deleting stuff out of tmp generally won't gain you much disk space.

if you do a du -h from /tmp it'll how much space the contents is taking up.

More then likely the mythback/frontend.log are taking up the space.

The echo line basically write "nothing" to the file, hence overwriting what's existing, and ultimately shrinking the file.

As a more permanent solution, you'll want to rotate the myth logs based on file size and only keep a few (or turn it off if you don't need it)

here you go for the /var/log/mythtv
Code:
root@mythtv:/var/log/mythtv# dir -S -l -h
total 244K
-rw-r--r-- 1 mythtv mythtv 39K Sep 16 06:26 mythbackend.log.6
-rw-r--r-- 1 mythtv mythtv 37K Sep 19 06:25 mythbackend.log.3
-rw-r--r-- 1 mythtv mythtv 36K Sep 15 06:25 mythbackend.log.7
-rw-r--r-- 1 mythtv mythtv 34K Sep 20 06:25 mythbackend.log.2
-rw-r--r-- 1 mythtv mythtv 26K Sep 21 20:00 mythbackend.log
-rw-r--r-- 1 mythtv mythtv 21K Sep 17 06:25 mythbackend.log.5

-rw-r--r-- 1 root   mythtv 566 Apr 24 02:45 KnoppMyth-run.log

I did a du -h from /tmp and after 5000 lines of results putty stopped remembering the files. Here is a small sample

So close... What we really needed from your "du" was the summary of space used. It usually puts the total at the bottom of the display. I think you can even do du -t to get the totals only. I may have that switch wrong, tho.

do this:
Code:
cd /
du -m --max-depth=1
Then look for the dir with the most stuff, change to that and do it again until you find the runaway file. example:
Code:
root@mythtv:~# cd /
root@mythtv:/# du -m --max-depth=1
1       ./lost+found
154430  ./myth
4       ./bin
5       ./boot
1       ./dev
11      ./etc
182     ./home
1       ./initrd
73      ./lib
1       ./media
1       ./mnt
1       ./opt
261     ./proc
12      ./root
10      ./sbin
1       ./srv
0       ./sys
2       ./tmp
1941    ./usr
252     ./var
1       ./cdrom
1       ./.qt
4       ./tftpboot
334     ./nfsroot
157516  .
You can ignore /myth since that is on the other partition. In this case there are no real standouts, but often you may find a log file somewhere under /var/log that is getting really big.

I don't want to confuse the issue, but I'd check /home/mythtv/.xsession-errors

Code:
ls -l /home/mythtv/.xsession-errors


This file has given many people trouble in the past. If it's huge, add the following to the end of /etc/logrotate.conf

Code:
/home/mythtv/.xsession-errors   {
rotate 5
daily
}


This will rotate the file daily, keeping only the last 5 days of logs.

Hi,

Actually, once you find the large file you may want to do a tail -200 /path/to/bad/guy.log |less and look to see what is causing the entries. Then shrink it and fix the issue so it doesn't re-occur.

There are three logs that have gotten large in the recent past that come to mind,
mysql (R5C7)
mythfrontend
& mythbackend
and the others are usually somethng not set correctly.

Mike

Thanks for all of your help I unfortunately won't be able to work on this until tomorrow night (I'm Working this stupid event) and I can't get Putty to work from the work network. The IT guys probably have something locked down.

to Liv2Cod there were no totals at the end of that file there were only file names.

Is there a way to sort du by size (make the biggest float to the top)?
Thanks again

Code:
du -k | sort -n

That leaves the biggest ones at the end, which is convenient if you just run it and look at the last page or so of results.

BTW - This an much more is covered in the LinuxTips page on the wiki.
