Comment 9 Stefan Jensen 2009-12-13 13:06:06 EST Just want to state, that i run into it, too. I was more than a little concerned my hard drive was failing since I've seen that message before on an Ubuntu 9.04 drive that was going south. How to get the same Emacs environment on a different computer?

Is dm-0 an LVM linear map across multiple disks?

And the error messages are very interesting and I can't make sense of the pattern. It didn't. Are misspellings in a recruiter's message a red flag? Buffer I/o Error On Dev Dm-0 Logical Block I was able to capture 2 points of data that seem to start out with the same error condition.This only seems to occur when a drive fails and the MegRAID rebuilds to the global hot spare, or if I force some action on the RAID which causes a drive fail and rebuild to an alternate disk (I had a few disks get SMART predictive failures and have been working to replace these with new).

Not the answer you're looking for?
