June 9, 201115 yr It's the same error. bread: Cannot read the block (2): (Input/output error). And my question is still not answered. With 2 drives down, neither being the parity, have I lost data? yes. If the two drives are un-readable, and neither is the parity disk, you've lost the contents of both. If either drive is readable, or can be made readable (perhaps by replacing a bad cable to it, of fixing a loose cable) then you can re-construct the remaining bad drive by use of parity and all the other data disks. If the two drives share a common power cable, or backplane, it might not be two bad drives.
June 11, 201115 yr Author I also have a hard time believing two drives went bad at the same time. However, I've tried moving the drives around to different backplanes in the Norco, different cabling and different controllers and so far there's no change in the behavior. I read reference to someone else trying Spinrite and while I might still try that I'm not eager to drop another $90 to fix this if I don't have to. Also, what's the difference between the red and orange dots?
June 11, 201115 yr See here for colors: http://lime-technology.com/wiki/index.php?title=Un-Official_UnRAID_Manual#Colored_status_indicator Orange=yellow for some reason.
June 11, 201115 yr Author Thanks, so.... My "yellow" drive should be "A data disk has this status during Reconstruction" and yet there doesn't seem to be any reconstruction going on. I'm guessing that's because I'm having trouble with the second disk?
June 12, 201115 yr Author Ran Disk6 through Spinrite and it didn't find anything. However it now shows as being too small so something changed. How do I fix this?
June 12, 201115 yr Author Ok, this screenshot is after I removed the HPA problem which I picked up trying to run Spinrite on another system. This is slightly different than previously because both drives are now yellow (orange really). Is that a good thing or inconsequential? I'm close to trying each drive in another system to see if I can recover the data at a minimum. Any suggestions before I do that?
June 20, 201115 yr Author Ok, I've got it where both drives are returning output when I do any of the reiserfsck commands. I've run "reiserfsck --scan-whole-partition --rebuild-tree" and rebuild-sb on both drives and got references to things getting fixed and moved to lost and found. The Unraid web interface still doesn't want to mount the drives though. So, how can I mount the drives and get the data back into the array. I know I'll also need to inspect lost+found.
