you'll have to, and lets hope it works because that is all I can think of
before i do it:
I do not understand that the Wiping helps with this problems:
Coderoot@MEDIASERVER:~# mdadm --readwrite /dev/md127 mdadm: failed to set writable for /dev/md127: Device or resource busyCoderoot@MEDIASERVER:~# mdadm --stop /dev/md127 mdadm: Cannot get exclusive access to /dev/md127:Perhaps a running process, mounted filesystem or active volume group? -
Because you can add a drive to a degraded even with the raid running as it appears in raid management as clean/degraded. OMV is designed and written so that everything is done from the GUI using the cli is usually a last resort and even then it should be avoided.
I do not understand that the Wiping helps with this problems
It doesn't, the fact that you cannot add the drive back to the array from the cli or the gui, it's one of the options to try, the other is to look in omv-extras and look at the section systemrescuecd, this can boot on a one time only and allows to repair/troubleshoot without interacting with OMV. However, this all cli and is not for the faint hearted and should be used as a last resort.
When you reinstalled and set your server up again I have no idea what may have gone wrong, but something did.
Using such large drives within an mdadm raid is like running a raid0, and the worst is you have no backup!! I have no problems with users having a raid setup providing they understand how to look after it and resolve any issues. Raid is about availability, so if a drive fails it still functions and that's the only reason.
So the two choices are yours, wiping the drive may not work, if it doesn't then it's the systemrescuecd option, hopefully that works, if you had a backup a simple start again by wiping the drives and recreating the array after removing smb and shared folders.

First time I've seen this
what's the output of wipefs -n /dev/sdd -
Get in contact with WD support. They will send a replacement in advance (they block an amount on your credit card in case you do not send the disk back) and you can return the drive in the packaging they send you.
