Title:
logrotate does not rotate logs (rsyslog)
Status in logrotate package in Ubuntu:
Confirmed
Bug description:
(Expected: auth.log, kern.log, syslog rotated "daily"/"weakly"
according to /etd/..., actually: no rotation even after weeks; and
manual forcing may fail.)
Being concerned about the amount of GBs that a Lubuntu persistent
installation on a USB flash drive may write per day, I observed that
auth.log, kern.log, and syslog grow to many MB. They may get about
1000 entries a day, resulting in many GB load for the USB drive per
day. I learnt about logrotate and rsyslog and modified
/etc/logrotate.conf and /etc/logrotate.d/rsyslog. Yet none had any
effect.
I have kept USB installations of Lubuntu 14.04.1 in parallel and saved
them after some days, so I could report about a number of experiments.
E.g., I started 2014-08-31, and I have a snapshot from 2014-09-22
where I had not changed /etc/logrotate.conf, neither
/etc/logrotate.d/rsyslog ("daily", "weekly"), and the three files
still have the entries from 2014-08-31, although three "weeks" had
passed.
#51879 (2006) and #1278193 (Feb 2014) are very similar, however:
* I observed growing kern.log and syslog to more than 100MB (to "out of memory" finally) in some installations in summer 2013; in later installations the same year and before 14.04, the problem vanished (I watched the sizes manually/regularly – difference to #51879: after 2006, problem recurred, vanished, recurred).
* With Lubuntu 14.04.1 recently, I changed "weekly" into "daily" in /etc/logratate.conf and in /etc/logrotate.d/rsyslog, but three days later auth.log, kern.log, and syslog still had no older copies and still contained messages from the last three days. Then I did sudo logrotate-f /etc/logrotate.conf, which works, but still after another three days those three logs had not been rotated.
Actually I also have tried sudo logrotate -f /etc/logrotate.d/rsyslog,
and the result has been exactly as #1258202 (2013). As opposed to the
latter report and that for #1278193, I am unable to guess from which
changes the problems might have resulted.
