One of the ports on my main machine appears to have gone bad.  It's a long story but the ESata would connect to the 4 drive bay properly, but after about 15 minutes the drives would spin down and I could not spin them back up.

Added to the join I discovered this issue halfway through a parity check which stopped at 33% ... so my Parity drive may be full of bad data.

I've replaced the cable, same issue.  Tried another cable and it wouldn't even see the enclosure.  Tried another enclosure, same issue as first enclosure.

 

I decided to see if USB worked, and being UNRAID I was sure it wouldn't... and was surprised that Unraid 6.2RC appears to support USB (I've been around a long time, so forgive me for missing this... 4.7 days)

 

However USB changed the ID of the drives by adding some USB Specific code to the drive Serial name.  I've manually mounted the drives and confirmed they are in the proper spots.  It helped they were 2TB, 3TB, and 4TB so could tell by size as well.

 

However I'm stuck with the To many missing or incorrect disks cfg error.

Is there anyway to fix this so I can try to see if Partiy will restore (did I forget to mention?) the one drive that had died.

You can try this, if your replacemnt disk is the same size as the failed one:

 

-take a screenshot of current array assignments

-tools -> new config

-reassign all disks, assign new disk of the same size in place of the failed one, double check parity is in the correct slot

-very important, before starting array check “parity is already valid”

-start array

-if you're using a new/empty disk as replacement it will appear as unmountable, it's ok for now

-stop array

-unassign failed disk (select “no device”)

-start array, check that the emulated disk now mounts

-stop array

-reassign replacement disk

-start array to begin rebuild

so my Parity drive may be full of bad data.

 

Naturally, if this is true the procedure above won't work.

thanks john.  Its worth a shot.
