Operating system Linux Joplin version 3.1.12 What issue do you have? I have installed a Joplin server (latest version) on my synology Nas and as soon as it is enabled in docker the server writes on the hard-drive at ~1MB/s therefore I constantly hear my hard-drives writing noise. This happens even…

If you look at the log, what is the server doing?

Here is a log extract. But the taskservice #11 occure every 10s and for less than a second. Whereas the disk activity while the Joplin server is up is continuous. I does not seems to explain the constant writing on disk. 20:51:08 0|app | 2024-09-16 20:51:08: TaskService: Completed #11 (Process sha…

Hmm, but that wouldn't produce 1MB/s. It's every 10 seconds, and no data should be generated except for this log statement

You confirm that it is not an expected behavior (the constant writing on disk) ? I will try to find out what is written on disk.

No it's not expected, but I don't know what could be causing it

I have a file in the the joplin/pg_wal directory that is updated every 10s but it's size remains 16Mo. File name is 00000001000000000000007A. Could WAL be the culprit? 16Mo every 10s is coherent with the writing rates I get from the nas performance monitoring tool.

This is a file that's managed by Postgres and it's indeed going to be written to every time there's a log statement. I don't know how your server is setup but generally you shouldn't mirror this file since it's to manage current transactions, not for data.

I am not sure it's the raid mirroring in fact just the 16Mo every 10s is coherent with the writing rates I get. Is there a way to prevent log to activate the update of that WAL file? Or to disable log

Not currently and I'm not sure it's something I'd want to add support for at this point.

Is there a way to select a log level to limit log to errors?
