unexpected reboot - looking for logs

[dustmaster]

Hi there,
I did a fresh install of Truenas 12.0-U7 because I replaced the system drives. Then uploaded my old settings. Which then "automatically" imported my old Pool.

Everything seemed fine, so after a few minutes I went on and deleted an old Dataset I did not need anymore. Immediately after that (I doubt that there is a connection though) - the system rebooted unexpectedly. Now everything fine again.

Well - I hate those errors which aren't reproducible, so I'd love to check on that. I did not see the console output of the machine at that particular moment and I am lacking ideas where to start to read, apart from the usual /var/log/... In the IPMI hardware events I did not find anything susceptible.

Do you have any ideas how to troubleshoot this?

Thanks!
DM

I checked on the messages log and found a "reboot by root" preceding the reboot in question. So it doesn't seem to be due to a crash or something ..

Do you know of any log where I could find a notice of the deletion of the dataset? Haven't found it so far ..
