undo new config command

[lovswr]

So I did something really stupid.  I wanted to reconfigure my array because I have a 3TB drive with just over 75% usage & a 4 TB drive at zero percent.  So I stopped the array & removed the 4TB drive.  Went to new config  set that command.  However I did not write down/take a screen shot of what drive was what (particularly my single 4TB parity).  Is there a way to undo 'new config' or at least see which drives were assigned to which slot?

No way to undo, do you have a flash drive backup or some saved diagnostics?

As a matter of fact I uploaded a diagnostic file on July 6th of this year.  It is in this thread but I cannot download it?

Yep, this has to do with the forum change, maybe you still have it on your desktop?

 

If not safest way to find out which disk is parity is to mount them read-only one at a time, so that parity remains in sync, you can see how to here, the disk that fails to mount is parity, if more than one fails to mount ask for help.

Thank my lucky stars (I think).  I found that diagnostic file on my desktop.  I searched around  several files & it seems that df.txt has useful info.  It has all drives listed but not the serial correlated to the assignment that the drive controller gave.  It does have used & free space, but how do I figure out which drive goes where?

See system\vars.txt, it has all the assignments.

Yep, I just found it about 1 minute before your response.  Parity is rebuilding now without that empty 4TB drive.  After rebuild I will just swap out the mostly full 3TB for the empty 4tB.

 

Thank you for your excellent & speedy assistance.
