I'm trying to capture what looks like a kernel error/stack trace when I run the command sudo zpool import. There error starts with:

[104.877657] BUG: unable to handle kernel paging request at 00000000ffff4167


I've tried simply redirecting stderr to a file with sudo zpool import &> err_file but that doesn't seem to capture it (I'm using bash) - the error still prints to the screen.

How can I grab the entire error message?

  • You will most probably need to redirect the error to the file as at the moment, it is redirecting to screen and so use "sudo zpool import 2> err_file" – Raman Sailopal Feb 1 '18 at 12:10

The error message isn't being written to the console by the zpool command. The kernel is writing the message. It's most likely being written to the console via syslog/rsyslog.

You might be able to find the error message by running dmesg which will print the kernel messages. dmesg > err_file
