Post subject:  Root is full <solved>
I installed LH 6.03 a while back for my neighbor (who has no linux experience). Of course I have been his tech support ever since ;-) Lately he has been very upset at the apparent demise of his system and I had a few moments today to check it out - after being shocked at the myriad of errors and problems I realized root was full. Using 'du' I can see the var directory is the second biggest after /myth. I deleted the rotated log files from /var/log/ & /var/log/mythtv but it still shows 100% full but oddly 24 of 25GB used, MySQL still failed to start. Then I had to leave. Before I head over there again, has anyone any other suggestions on what would be good candidates for deletion?

Thanks.

Hi Paul,

You will have to restart anything that is using those files: Linux will hang on to them until they are not being used. Try restarting myth backend and run du after you delete them. You may want to find out what caused it to fill first, though.

Mysql nearly always corrupts when root fills. You should run mysqlcheckdb with -r option to find and fix. Run it again before attempting to start mysql. From memory (warning: I have several faulty memory modules) it should be something like "mysqlcheckdb -u root mythconverg *"

Finally, it may never get to actual 100%, as a few % is usually reserved for fs stuff.

logrotate can help you further. Not sure why this isn't the default, but it can rotate logs based on size and only keep a couple (you set the number of old files). This will prevent your fs from filling which, as you have discovered, is very annoying and inconvenient (but a great learning experience).

Good luck

Mike

Ouch. This is always ugly. As manicmike said your db will almost certainly need to be repaired. As for the cause of the partition filling up, logfiles are almost always the prime suspect, and in the current system the acpid daemon is one of the more common culprits. (Searching for "acpid" should turn up a couple threads about the exact problem.)

When my root filled up it was because of firefox downloading to that partition. I was able to use gparted to increase the first partiton.

another problem is the pacman cache directory ...

check for with "ls -l /data/var/cache/pacman/" or "du -h -x --max-depth=1 /
data/var/cache/pacman/

my old R6 system has over 1.8GB files there, the following command will help :-)

Thanks all. Got enough free to make it run and it did require a repair of the DB so thanks for that tip... Will keep searching for more stuff to delete.
