Subject: /: file system full
I got the following message when I try to rebuild kernel, but I also
get the "file system full" message at boot:
Apr 12 12:34:44 ps1 /kernel: pid 293 (install), uid 0 on /: file system
full
Good things to look for when / fills up:
- big things in /tmp (or a lot of old things in /tmp) (you looked for
those, and didn't find them).
- look at the size of files in /var/log, /var/spool, etc.
- look to see if anything in /dev is a regular file (/dev/mt0 or other
tape device is popular choice for this --- someone with appropriate
privileges typing ``tar cf /dev/mt0'' on a system where there is
/dev/mt0 will get no indication that the bits are going onto disk
(into a regular file named ``/dev/mt0'') and not onto their tape.
Especially now that tape drives aren't big vacuum-column-filled
things with nine-inch reels that you can *see* are turning.
A good (albeit time-consuming) command to use when looking for the
root-filesystem-eating file is ``du -s''.
in directory /, ls -s gives:
total 1348
1 .cshrc 1 bin 9 dev 1 lkm 0 sys
1 .profile 1 boot 1 dist 1 mnt 1 tmp
1 A: 0 boot.config 2 etc 1 proc 1 usr
1 C: 2 boot.help 0 home 1 root 1 var
4 COPYRIGHT 1 cdrom 0 kernel.config 2 sbin
1 D: 0 compat 1312 kernel.old 1 stand
Here's a subtlety. ``ls -s'' is not telling you how much space files
in /tmp or /dev are taking up. It is telling you the size of the
files containing the directory information.
