Should I open a PR? Not sure there is enough to go on for a PR, but something is weird. Friday morning our power went down at home for about three hours after I had already left for work. When I came home I found the router/gateway box was OK. It is still with the old DOS mbr and disklabel scheme, with softupdates, and is a pair of disks gmirrored. The other box is my first foray into the land of GPT, along with SU+J. It was sitting at the 'couldn't mount... Press return for /bin/sh' line. There was an error indicating that replaying one or more journals had failed. I was able to successfully fsck all the other partitions (besides /), then rebooted and system came back up OK. Both of these machines were recently updated to 9.2 Release from 9.1. It has been approximately 9 months, or so, since I last had a power outage like this one. Back then they were still 8.3 I think, did not have SU+J and recovered just fine on their own. This error about the replay of the journal(s) failing is somewhat disconcerting. Beyond that, however, I do not have any other details or data. Nothing to flesh out a PR, but thought I'd mention what I saw in conjunction with your experience. -Mike
