So I'm in a bit of a bind concerning my array. I have a dual parity drive system (2x 6TB) and had both a parity drive and a data drive fail. I ordered 3x 16TB drives with the intention of replacing the failed drives, as well as 16TB upgrade for the 'working' parity drive so I can upgrade the max drive size in the array.
I was going to begin by doing a doing the parity copy/swap procedure outlined in SpaceInvaderOne's Video 'How to Replace a Failed Data Drive with one LARGER than the Parity' https://youtu.be/MMlR0TMeKsI?t=238 @3:58
However when I began the copy it would fail almost immediately and stop the array. Read errors with the remaining 6TB parity drive...
This is where I might have messed up. Thinking I was going to lose the data on the failed data drive. I just added the 16TB drive as a 2nd parity drive and hoped it would build the parity for it successfully. The parity build completed but with 800+ errors.
Now my first question is was the new 2nd parity drive able to build its parity correctly even though there is a missing data drive in the array?
If the new parity on the new drive was built correctly, can I now replace the remaining 6TB parity drive, the one throwing up errors, with the a new 16TB drive and still keep the data on the the failed/missing data drive intact? And if so should I do a manual error correcting parity check before I replace the remaining 6TB parity disks w/ the errors?
Thank you in advance for the help. I attached the SMART report the 6TB parity drive throwing up errors and a diagnostic log. Can post relevant logs/info if need be, just let me know what I need to provide.
