Hi,
We recently migrated the samba-ad-dc from 4.6.5 to 4.7.1. Over a period
of last 15 days or so we have been observing that although the samba log
rotates, upon rotation, samba will start writing the logs to both the
main log file and the <main log>.old file simultaneously. While, the
main log file rotates properly, instead of deleting old file and create
a new one on rotation, samba continues to write into the <main log>.old
file and file size keeps increasing.
Any suggestion to fix it? Also, we need some suggestions to use wild
card such as %h, %m etc for samba log.
Our smb.conf is shown below.

This is what i have to use on debian wheezy: /etc/logrotate.d/samba ----------------------------- ... /var/log/samba/log.samba { weekly missingok rotate 7 copytruncate compress delaycompress notifempty } ----------------------------
Hi, Continuing on the same subject, the VARIABLE SUBSTITUTIONS are not working. for example, I want to have the date & time attached to the samba log file. Hence I modified the smb.conf log file = /var/log/samba/samba.%T.log The file with name "samba.%T.log" gets created in /var/log/samba folder and %T will not get substituted with current date & time. I request for your guidance to correct this part. Also the samba continues to write into .old file as well and not finding any means to correct it. Many thanks for your guidance in advance. -- Thanks & Regards, Anantha Raghava Do not print this e-mail unless required. Save Paper & trees.

See here about your logfile issue https://bugzilla.samba.org/show_bug.cgi?id=12935. As I laready wrote, using copytruncate for logrotate fixed that issue for me. I also assume your system does not use systemd. I do not use variables so someone else may jump in here. Sincere, Achim~

Now part of this is due to global variables and multiple clients per connection, but it doesn't really excuse us also skipping things like %T.> I request for your guidance to correct this part. Also the samba > continues to write into .old file as well and not finding any means to > correct it.I think this is because each process only checks if the file should be rotated every few lines, so they can hold the log open for quite some time. Ideally a global signal would be sent saying which file (or even just that a file) just got rotated, so everyone can re-open. Patches are most welcome!
