[gentoo-server] Errors from cron

[gentoo-server] Errors from cron

[A. Khattri]

Every once in awhile I get an email from cron about failed compression of
man pages (?) - any ideas what causes this? See:

Subject: Cron <root@zara> test -x /usr/sbin/run-crons && /usr/sbin/run-crons

This is probably caused by /etc/cron.daily/makewhatis trying to
decrompress man-pages to scan them for its database.
* Do these files really exist?
* Have you tried to decompress them to stdout manually (# bzcat <file>)?
* Are they really bzip2-files? (Check with   # file <file>)
* Ist your disk full?
Try reproducing the error by running
# makewhatis -w -v &> makewhatis.log
as root and check the logfile.


Bye,
Daniel

Here's an example email I got today:

> bzcat: I/O or other error, bailing out.  Possible reason follows.

OK, so let's check that file:

# ls -al /usr/share/man/man8/./hdparm.8.bz2
-rw-r--r-- 1 root root 8569 Jul 24 10:15 /usr/share/man/man8/./hdparm.8.bz2

Looks OK. I ran bunzip -c on the file and it displayed without any errors.

I also ran makewhatis manually and I got no errors at all.


One thing I have noticed is that I get these after an update (there was a
recent update to hdparm).
