System dataset is using to much space

[paolo.chieco]

Good evening,
I was deleting some old files on my Truenas SCALE.
Removing some old datasets I notice that the total space usage of the pool doesn't match the sum of the child datasets.
(Ignore the pool name, it is made by two 1TB Disk in Raid 1. I named it Raid0DataPool by mistake years ago and never bothered to change it)

Digging more deeply I have discovered that around 139GB is occupied by the system dataset. To be more specific a log folder

So I run:

Code:

 du -h /var/db/system/syslog-e6cb7c26dd1243d3962c3f87f9eddfe5/log

So it turns out that is a samba log file ( log.rpcd_lsad ) that is hogging around 138GB of space:

My questions at this point are:

• Is it normal that a log file can grow this much or could it be a bug? Is there a way to limit it (log rotate or from gui)?
• Can I safely clear/delete the file?
• Those log message is something i should worry about?

Thanks you in advance.

The log file sizes generated by samba should be capped in size. What is output of ls -lh /var/log/samba4

Good morning,
thank you for your reply.

Here's the output of ls -lh /var/log/samba4:

Interesting. Samba's debug library is supposed to cut this off at 5 MiB size. Delete that file, then generate a debug and PM it to me.
