[flourishing]

I tried to make migration of poste.io. when i tar it, too many logs. it tooks about one hour to pack it. how to clear the logs. and which logs or directory or files we can delete them ? thanks .

I don't understand what you mean by "make migration". All the data and configuration is stored in the data volume, so that should be all you need. Logs are in the log subdirectory of the data volume, and are automatically rotated, unless you're using a really old version of poste. (There is an old version that would accumulate tons and tons of logs on a daily basis due to failed rotations.)

sorry . i mean I try to move poste docker container to another server. when i try to backup the data volume, it has many many log files. it take me one hour. i used the latest docker image, which downloaded about 7 months ago. so i don't know is it too old or not . I will try to upgrade to the newest version. see what happend. thanks for the response quickly.

So, this was the log rotation issue: https://bitbucket.org/analogic/mailserver/issues/818/roundcube-logs-are-rotated-recursively - it was fixed as of 2.2.27, but if you ever used an older version you would likely have excess logs even after the problem was fixed. You'll want to check and see if there's a huge roundcube/logs directory under the data volume, and delete those files.

With regard to the "directory already locked" problem, my guess would be that you backed up the data volume while the mail server was running and thus have a lock file present? Probably you will need to do the backup with the mail server offline. I was not able to find anything on Google about that error, so I don't know for sure.
