Quota Exceeded - Critical warning -- however path does not exist.

[KevDog]

Hi I'm using TrueNas 12.0 U2 -- I received this critical warning within the alerts section:

CRITICAL
Quota exceeded on dataset tank/.system/cores. Used 100.00% (1 GiB of 1 GiB).


I have the tank dataset mounted at /mnt/tank however I don't have a .system/cores subdirectory:

freenas% cd /mnt/tank/.system/cores
-bash: cd: /mnt/tank/.system/cores: No such file or directory

Is this warning in regards to something else?

mount will show you where that dataset is mounted. Or zfs list.

This is mounted at /var/db/system/cores. You may have many core dump files there, and will need to delete a few.

@Patrick M. Hausen and @Samuel Tai

Thank you. I deleted some of the core dump files.

Out of curiosity, what were the core files? Ideally, we shouldn't have anything being generated there.

I am getting a similar alert:

Quota exceeded on dataset Daten/.system/cores. Used 95.44% (977.3 MiB of 1 GiB).

However, neither with mount or zfs list I am getting to a path that contains anything...

I'd assume the files under "." and ".." aren't the ones to be deleted :)
