Showing 2 drive failure and 1 wrong identification

[ltgunhole]

Okay so kinda had a perfect storm of dumb moves and bad luck and would really like any help I can get. Ill kick it off with some specs I have a HP DL 360 8 Drive server. It has 2 Parity 3 Data and 1 Cache Drive. Its running Docker Containers and a VM. Typical plugins like fix common problems, unassigned drives and community apps. I'll start with the user error I had a failed drive I got a replacement in and figured I would swap it out real quick and I clicked the release to eject the drive which happened to be the wrong drive. So i pushed it back in and went ahead and added in the other drive and went to start the array with Now 2 "failed drives" Well the system was at mounting filesystem when I lost power and i do have a UPS but it only holds for a few minutes as of lately and usually its not a big deal cause I have unraid to shutdown pretty quickly when i have a power loss. But since it was mounting it wasnt shutting down. So while the safely shutdown was an option still showing I shut it down not sure if it succeeded or not since it did all lose power but a few minutes later I have power again and my gear spins back up. So I login to start the rebuild and my parity drive is now show up as wrong identification. At this point its a little above my head on next steps. I did do another clean reboot and still shows. I know my Parity drives are good Im also pretty sure my drive 2 is good since nothing should have been writing to the array I have the logs i will attach not sure if there real useful since it did reboot.

Please post the diagnostics: Tools -> Diagnostics

 

P.S.: next time also please use paragraphs when describing a problem, much easier to read.

Okay Will do!

The RAID controller changed the ID of the parity disk, this is one of the reasons we don't recommend using them.

 

Also because of it can see SMART for disks 1 and 2, see if you can get them manually.

Here is the SMART reports for all the drives. I had to run them in terminal and copy them to a TXT file. I hope that works. 
Disk 1 is the replacement drive.

So disk1 is a new (to the array) disk and disk2 was the one ejected by mistake?

[ltgunhole]

Yes Sir that is correct. 

[JorgeB]

Assuming disk2 is OK and parity is still valid you can try this:

 

-Tools -> New Config -> Retain current configuration: All -> Apply
-Check all assignments are correct and assign any missing disk(s) if needed, like old parity and new disk1
-Check both "parity is already valid" and "maintenance mode" and start the array
-Stop array
-Unassign disk1
-Start array (in normal mode now), ideally the emulated disk will now mount and contents look correct, if it doesn't you should run a filesystem check on the emulated disk
-If the emulated disk mounts and contents look correct stop the array
-Re-assign disk1 and start array to begin rebuilding.

You Guys Rock! That seems to be working and Drive 1 is rebuilding.
