Post subject:  Help me find disk space

My system recently ran out of space on / and so they system locked and wouldn't start the front/backend processes. I went in and deleted the MySQL logs, but that only freed up 220MB. I am curious if there are other things I can look at to delete so that I can free up more space. Here is where it looks to be mostly distributed:

Code:
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda1              4424356   3975188    225064  95% /
/dev/hdb1            488252928 233361476 254891452  48% /myth

root@mythtv:/# du -k | sort -n | tail -20
90112   ./usr/share/mythtv
95900   ./usr/share/doc
108348  ./var/lib/mysql
150764  ./usr/bin
174920  ./var/lib
222672  ./var
420236  ./usr/lib
513060  ./usr/share
528298  ./proc
1235604 ./usr
I pulled out the entries for /myth as they are on another drive. Does the KnoppMyth install really take up 4.2GB? Is there something in one of these directories that I could probably remove?

The folders I would be looking at for space would be:

/var/logs
/tmp
/home/mythtv
/home/your-user-name
/root

Since the / partition is finite in space it can fill up rather quickly, especially if you have downloaded source and compiled and installed but not removed the source files.

go to the root folder
Code:
cd /

type the following to see how big each folder and file is
Code:
du -sh *


look at the folders and see what is taking up all the space.

Most likely somthing in /var/logs

For somthing to compare to here is one of my frontends that has a pretty clean install
Code:
root@mythtv-bedroom:/# du -sh *
0       0
3.3M    bin
5.1M    boot
8.0K    cache
4.0K    cdrom
140K    dev
17M     etc
36M     home
4.0K    initrd
4.0K    knoppmyth
4.0K    knoppmyth-sata
77M     lib
16K     lost+found
4.0K    media
4.0K    mnt
16M     myth
4.0K    none
4.0K    opt
448M    proc
48K     root
8.3M    sbin
0       sys
28K     tmp
1.7G    usr
65M     var
0       vmlinuz
root@mythtv-bedroom:/#

IIRC 5C1 had issues with not rotating logs, there should be a fix somewhere else here.
If you you use mythstream a lot to listen to po^Wnetcasts or internet radio you will run out space on / as the mythtv home directory (where the downloaded files are) is held on the same partition.

I had a 'test' directory in /mnt/ that held some 2GB for files. :oops: Deleting that cleared up enough space for a while. Muchos gracias.

Should my /var/lib/mysql/mythconverg be 86MB, or is this normal for a system that has been used for a for over a year?

Mine is 136Mb...
Code:
root@black2:~# du -m /var/lib/mysql/mythconverg
136     /var/lib/mysql/mythconverg

So that seems pretty reasonable to me.
