How to get more information after forced restart?

[zfsfan]

The system restarted after

sudo zpool export -a

with the usual error message (system restarted because of error, please enter key to continue).

How can I get more information to submit a bug report?

You might get a .panic report in /Library/Logs/DiagnosticsLogs/

but if you have nothing there, ... there is nothing else

[zfsfan]

In /Library/Logs/DiagnosticReports there are two files:

-rw-rw-rw-@ 1 root _analyticsusers 7,5K 15 Apr 01:22 .contents.panic
-rw-rw-rw-@ 1 root _analyticsusers 1,5M 15 Apr 01:22 Kernel-2023-04-15-012207.panic

The small file contains this text mentioning org.openzfsonosx.zfs:

Looks like a panic in ZFS yeah, hard to tell any more since Apple strips everything
