Missing Data after attempt at drive replacement

[mjone4]

Looking to get some help before I mess things up more than I probably already did.  I thought drive replacement was going to be easier than I came across.  I will attempt to describe what I have already done and what I'm trying to fix.

I had a data drive fail and ordered multiple new drives that were larger than the previous parity drive.  Previous drive setup was 1 parity, disk 1 of data failed and then disk 2.

I believe I did a New Config and currently have one of the new drives in the parity slot, a new drive in the first data slot showing xfs and seems to be running, a new drive stating "Unmountable: Unsupported partition layout" in the second disk slot and the old parity drive in the 3rd data slot stating "Unmountable: Unsupported or no file system."  Cache drives unchanged.  Old disk 2 is currently not connected to the system.

It seems at though it is remembering some of the shares, but none of the data is in them.

Am I past the point of saving the old data after a new parity was built?  Can I save files from the old disk 2 and move them somehow?  I would appreciate any guidance you all can provide.

Thank you!

You cannot do a new config when you want to replace a drive, which disks were old disk1 and disk2? Are those still intact?

[mjone4]

Old parity is now unmountable in disk3, old disk1 failed. Old disk2 should be fine but is currently not attached to the system. 
 

I’m pretty sure I did a new config in order to get the new parity drive setup.  Likely was a mistake as I’m finding out.  Just looking to see what I should be able to recover at this point.

 

Thank you for your help

Did the old disk1 actually physically fail or simply get disabled and/or marked as unmountable? 

[mjone4]

It was marked as disabled and I assumed it was nonfunctional.

It may be worth connecting the old and posting a SMART report, alternatively we can try to emulate disk1 again, but that will only work if parity is still valid.

More often than not when a drive is disabled (because a write failed) it was due to an external factor and the drive is physically OK.

So I plugged in the previously thought to have failed old disk1 and ran the smart test and it says passed.  I ordered more cables so I can plug all the drives in and then see what happens.  Is there a process I should do like make them unassigned and then try to look and see what files are on before I add them to the array?  I appreciate everyones help so far.

You can mount the old disk with UD and copy the data to the array.
