I'm sure I'm to blame, but still it's kinda strange that this could have happened.

 

I've (had) basically filled up the first four Terabyte disks on my unRAID, so I inserted two more. In the Main menu, I noted that there were two unformatted disks, and I consequently clicked for them to be formatted.

 

To my horror, I notice that the lamps start flashing on two of the existing drives in the array. No way to stop this, so after some quick comtemplation I decided to power down the server.

 

Since two disks got f...ed, it seems that restoring is out of the question, or?

 

Admittedly, my mind was somewhere else (our huge Caucasian Shepard had just vomited all over the back seat and yours truly...), but I'm still kinda thrown as to why unRAID would identify two existing disks as unformatted, and allow me to go ahead and format them without a confirmation dialogue, identifying the two disks and giving me a chance to abort.

 

Time for some RTFM and calming down, I guess. Still, any advice is welcome.

 

Cheers!

Once you get a minute or two to step back... here's what I would try...

 

Power up the array and see what it thinks has happened.  If two existing drives were being cleared, as you suspect, then the array will probably not start as they will be unable to be mounted. 

 

Do not start the array or press the "Restore" button...  IT DOES NOT RESTORE ANYTHING... Instead, it "Stores a new configuration, based on the currently assigned and working drives, and then re-computes parity based on those.

 

Report back with what you see on the main management page of your array.
