Mount – Where to Find the Log Files for Mounting Disks

hard drivelive-cdlogmount

I understand if I boot from a live cd I can see all the system logs under System > Administration > File Log Viewer

I have a major error with a disk not mounting and I want to trace i tback to the last time it did work and what may have corrupted the ext4 filesystem on it.

So within the File Log Viewer Where do I start examining?

I'd guess /var/log/dmesg

You can find all logs that mention mounting or ext4 like this:

grep -e mount -e ext4 -lR /var/log 2> /dev/null

dmesg seemed to be the most relevant to me. And there are archived versions (dmesg.*).
