System disk keeps filling up...

Unread postby mnorton » Fri Apr 22, 2011 9:14 am

OK - so I previously thought this was a virus. It still could be.
My system disk space keeps filling up! I can clear up several gigs and then in a few hours POOF!!!! ZERO KB!
I backed up the HD with time machine and a disk image from disk utils.
Verify disk revealed no disk issues. As did the other disk util verifications.

I have nearly zero KB of disk space and I can't locate the culprit.

Any ideas on what I need to look at?

Mac OS X 10.5.6

thanks

Check where the space is going (look for one of the UNIX-based FS analyzers, or else run a "du -h" at the command prompt, provided your system has du, can't recall if it was default).

My first guess is that something's sending out absurd numbers of log entries.

Well I rebooted with theD-key down to run diagnostics. @x I saw this error reported.

4M0T/1/40000003:HDD-1334

I presume the HDD is the Hard Disk Drive.

So what is the skinny? Is my drive terminally ill?

thanks.

No, Google seems to suggest that is an issue with the hard drive fan, not the drive itself. It's still more likely you have a runaway process chewing up a log file or some such.

My brother had a similar issue on his powerbook, it would continually fill the disk with swap files (in /var/private/ somesuch). I don't have a cure, but it might be worth looking at, perhaps seeing if you could clear them out somehow.

Yes. It does appear to be some sort of a file being written. It is happening now. I am watching my disk capacity slowly get munched away.

Is there a UNIX command I can use to home in and watch what is being written?
I used du -x -h -d 1 /

And it didn't really give any deeper revelation to the problem.
I have omnidisksweeper running too...
thanks.

You can use the "find" command with the -mmin option to show files modified within a certain window of time. For example,

Code: Select all

find . -mmin -60
will list all files in the current directory that have been modified in the last sixty minutes. Use sudo to run

Code: Select all

find / -mmin -60
(or run it as root) to see every file on the computer that was modified in the last hour.

You can then use the "lsof" command to see which process is actually keeping the file open.

Fire up the log viewer and see if there's anything obvious there.

Note that if you have a 25GB log file the Apple GUI viewer will be very slow (seen it...).

You can also try using the find command with a size flag to find all files bigger than a gig or so - sometimes this works.

Just scan to see which folders took up all those spaces:

I found a thread on the Apple Discussion forums that looks similar; you might try deleting the files suggested in the last post:
