Log rotation
Hi All!

I seem to have a problem with log rotation, unless I am doing something wrong, I have type the following command for testing purposes to see if the
Code:
 -s

option works but he did not:
Code:
 logadm -w /var/adm/messages -C 8 -c -s 512k -t '/var/adm/messages.$n' -z 1

the file is now at this size:
Code:
-rw-r--r--   1 root     root     146452271 Aug  5 08:56 messages

and did not create copies of the
Code:
messages

file as stated on the
Code:
logadm -w

command.

Please can I have some help

Check /etc/logadm.conf to see, if the entry was written correctly and check root's crontab, if the /usr/sbin/logadm cronjob ist still there.

Did the logadm-cronjob run after you made your modification? This is not clear in your post. The statement you posted only updates the config file but does not perform any actions.

You can also try to run logadm manually with the verbose switch on:

Code:
logadm -v

Log rotation
Hi!

After running
Code:
logadm -v

it created another file
Code:
messages.0

and compressed
Code:
messages.1

, but now current messages file is bigger that 512K set
Code:
-s 512k

.
ShouldŽnt that file after reaching 512k being automatically renamed to
Code:
message.0

and created a new
Code:
message

file?

I am not sure, if it is necessary to send a SIGHUP to syslog when using the copy-truncate-option (-c). You might give it a try. Add -a 'kill -HUP `cat /var/run/syslog.pid`' to the commandline.

-a 'kill -HUP `cat /var/run/syslog.pid`' is necessary, because syslogd needs to close and re-open its file handle.
-c does not break anything - but slows things down.
