Locking up hard, sync errors


Recommended Posts

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.

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?

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?

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.
