I have been attempting to fix this for a few months with various attempts so I apologize in advance.

 

I have a 12 disk array with a double parity. 

 

To begin, I had a parity drive fail and while waiting for a new drive to come in unraid attempted to do a parity check and found errors. (this was months ago I do not remember specifics or logs). Two drives were then kicked out of the array, the second parity and disk 11 ( this is the drive of focus). When the array was stopped I would attempt to assign the drives to their spots but unraid would then kick them out and remove them from the ui. One guide suggested back wires so I replaced all pcie cards and sata cables (this is primarily were the delay came from). 

 

I have since attempted many guides etc and believe each of those attempts just messed the software side up. So this is where I am at now. 

One drive sounds like a bowling alley and isn't recoverable. The other two I can still access the data from externally. I had found a guide at some point but don't have access to now, that said I could manually replace the drive and so that's what I attempted. 
 

I got three new drives and cleared them, then cleared and hardware mirrored the data for disk 11 just to get everything back up and verified. I have the new disk in slot 11 but unraid insists that it's incorrect (yes). I thought the hardware mirror would overwrite the disk id but that seems to not be the case. 

I tried to rename the drive in unraid but it still recognizes it. Before I messed with config files or deleted historical device info, I gave up and decided to just ask for help directly. The search terms for this particular issue overlap with so many other topics that I have been un sucessful in finding answers. 

 

tldr: I need to overwrite the id for a disk slot so that a manually replaced drive is accepted.

 

Thanks. 

Wish you had asked for help sooner.

Can't really do that. New Config may be what you need, but can't make any recommendations until you

 

Attach Diagnostics to your NEXT post in this thread.

Yep

You want to assign a different disk as disk11. Is that correct?

 

The array thinks you are missing both parity disks. You can't replace a disk when you already have two missing disks.

 

What do you want to do about parity?

 

Both parities failed. (in fact all three drives were the same batch). I have two extra drives to go into the parity slots but assumed I would have to solve the disk 11 issue before I could do anything about the parity. 

 

Do you still have the original disk11, just in case the cloned disk doesn't have your data?

 

You can do both new parity and new disk11 all at the same time with New Config.

If any disks show as unmountable after New Config

 

DON'T FORMAT!!!

 

Post new diagnostics after starting the array.

Yes, and both parities. 

 

I will review that and come back. 

 

Should I attempt to use the old parities or just put the new ones in?

And to clarify, this will not erase anything?

New Config is going to rebuild parity, so no point in rebuilding it to old parity drives you don't intend to keep in the array.

New Config only rebuilds parity, it doesn't change any disks assigned to data slots. Make sure you don't accidentally assign a data disk to either parity slot.

Parity is being rebuilt two drives are shown as unmountable. disk 9 is file system disk 11 is partition layout. With 14's this will take a while so I'll come back in a day or so. 

 

I really appreciate the help btw.
