[gentoo-user] logrotate won't rotate portage logs

[Mick]

Hi All,

I do not understand why the log files within /var/log/portage/ will
not rotate on my PC, while they rotate fine on my laptop.  The
/etc/logrotate.conf is the same on both boxen:
==========================================
# rotate log files weekly
weekly
#daily

# keep 4 weeks worth of backlogs
rotate 4

# create new (empty) log files after rotating old ones
create

# uncomment this if you want your log files compressed
compress

# packages can drop log rotation information into this directory
include /etc/logrotate.d

notifempty
nomail
noolddir

[snip . . . ]

# when /var/log/portage gets big
/var/log/portage/*.log
{
    rotate 1
    weekly
    nocreate
    ifempty
    olddir /var/log/portage/old
    postrotate
 find /var/log/portage/old -maxdepth 1 -mtime +30 -exec /bin/rm -f {} \;
    endscript
    nocompress
}
==========================================

The only difference I noticed (other than the fact that I have two
year old portage log files in /var/log/portage) between the two boxen
is that the access rights of the 'old'  directory on the PC were:

drwxr-sr-x 2 root    root          48 Dec 23  2005 old

while on the laptop which rotates without problems are:

drwx------ 2 root    root          4256 Jan 13  11:20 old

This may be a bit of a red herring because even though I changed the
access rights as per the laptop, the PC still refuses to rotate the
portage log files.

Any ideas?  How do I troubleshoot this one?

Anyone? Anything I could look into?

Hm, "logrotate -d"? How's logrotate being called? E.g. if it's cron,
what cron daemon are you using? E.g. fcron and dcron don't support a
system wide crontab in /etc/crontab, so things in /etc/cron.* won't
ever be called.

Thanks HW, this is what logrotate -d shows re. portage logs:
================================
# logrotate -d /etc/logrotate.conf
reading config file /etc/logrotate.conf
including /etc/logrotate.d
[snip...]

reading config info for /var/log/portage/*.log
olddir is now /var/log/portage/old
[snip...]

rotating pattern: /var/log/portage/*.log
 weekly (1 rotations)
olddir is /var/log/portage/old, empty log files are rotated, old logs
are removed
considering log /var/log/portage/4052-ati-drivers-8.14.13-r3.log
  log does not need rotating
considering log /var/log/portage/4053-ati-drivers-8.14.13-r3.log
  log does not need rotating
considering log /var/log/portage/4053-xorg-x11-6.8.2-r6.log
  log does not need rotating
[snip...]
================================

However, the three files shown above as an example are more than 1 week old:

# ls -la /var/log/portage/
total 231058
drwxrws--- 3 portage portage    76632 Jan 20 09:48 .
drwxr-xr-x 7 root    root        1208 Jan 20 09:07 ..
-rw-r--r-- 1 root    portage     6301 Dec 25  2005
4052-ati-drivers-8.14.13-r3.log
-rw-r--r-- 1 root    portage      395 Dec 25  2005
4053-ati-drivers-8.14.13-r3.log
-rw-r--r-- 1 root    portage  9137458 Dec 25  2005 4053-xorg-x11-6.8.2-r6.log

I am not sure if it is cron related at all because it won't rotate
these files, even when I try it manually.  Anyway, both machines are
using vixie-cron-4.1-r9 which I have not modified whatsoever from its
default:
================================
# cat /etc/cron.daily/logrotate.cron
#! /bin/sh

/usr/sbin/logrotate /etc/logrotate.conf
================================

I thought of forcing it through and therefore I have now used the -f
option.  It seems to have moved all logs into the old dir.
================================
rotating pattern: /var/log/portage/*.log
 forced from command line (1 rotations)
olddir is /var/log/portage/old, empty log files are rotated, old logs
are removed
considering log /var/log/portage/4052-ati-drivers-8.14.13-r3.log
  log needs rotating
considering log /var/log/portage/4053-ati-drivers-8.14.13-r3.log
  log needs rotating
considering log /var/log/portage/4053-xorg-x11-6.8.2-r6.log
  log needs rotating
================================
Because it was forced it shows above that "log needs rotating".

Then it rotated them happily (I think):
================================

I don't know if you can see something amiss above.  I guess I can wait
for a week and see if this problem recurs.

Thanks again.

Hm, I've never fiddled with logrotate around so much, but if I'm not
misinterpreting the man page, you can rotate based on the age of a file
using the directive "maxage <days>". The "weekly" rotation seems to
have some state saving and checking on which rotation is based on.

You could cheat and use "hwclock" ;-) (if you do, don't forget
"--noadjtime" or your clock will skip drastically on each next reboot)
