The listing for the in dev command is missing Logical Device 1000E which should be showing between the JBOD at the top (Logical Device 10006, Position 0) and the RAID below (Logical Device 60000, Position 1). As far as I can tell from my unit, it looks like that would store a duplicate copy of the system files on Drive 2 (drive slot 1). Anybody have any ideas on why that would be missing? Looking at the listing it doesn't look like Drive 2 is dead, so I'm wondering what happened here.

The thing that really worries me is that it doesn't seem to be getting past Phase 2 on the last few times it's tried doing the disk check. That seems to be because of some damaged inodes.

My guess is that this unit was set to run the disk check "only when there are suspected problems" when starting up. And until he ran the disk check, nobody had tried to access a file that had a problem, with PANICs apparently not considered a problem that would trigger a disk check (I can't tell now because the original log file seems to have been replaced with the updated one). But now that the disk check has been run manually, it's discovered some problems and won't continue on to mount the raid.

In my case I ran the disk check option to repair the severe errors and that at least let me back up most of the files, while only losing some non-critical (to me) ones. I don't know if I'd recommend that path here until he's tried everything else, because that might lose him the very files he's trying to recover. If those files are VERY important then it might be safer to send it to some recovery experts. They have a lot more sophisticated ways of recovering the data, although it will probably cost an arm and a leg.

The above is just my opinion.
