Hello everyone.
A couple of weeks ago one of my four array drives died and I've been emulating that drive with parity drive for the time being before I god the replacement drive.
I just right now received the new drive, but just before I was going to get it, yesterday another one of my drives suddenly stopped working.
In the array it shows up as "Unmountable: wrong or no file system". When the previous drive died it didn't show up like that, it just gave me I/O errors and gave me warnings, etc. This one just showed up like that out of the blue.
So right now I have Disk1 and Disk2 working properly. Then the Disk3 is "Unmountable: wrong or no file system". And then Disk4 is unassigned and emulated with parity drive.
I actually had way more data on Disk3 than the Disk4 (Disk4 was a recent purchase, like a month or two ago, about 2-ish TB used from 12 total, while 12TB Disk3 was almost all the way full)
What do I need to do to fix the situation?
I don't even know what kind of logs to post here for anyone to help me out, but i really need help though.
