Drive switched to "Unformatted status"

[sunflashx]

I've got a drive that spontaneously flipped to being unformatted.

 

Initially I noticed I was missing a bunch of files, but it reported no errors, data that had been then an hour ago suddenly went missing.  I shut the array down and brought it back up and when it did the flipped the one drive to unformatted.

 

I panicked and replaced it with a spare that I had, but the rebuilt apparently just rebuilt the same broken state the disk was in.

 

(Edit)  I ran xfs_repair on /dev/sdx, but that seems to have been incorrect, I needed to do /dev/sdx1 to tell it the partition.  Rerunning that now.

 

Any suggestions on recovering the data on that drive?

You should be running it against /dev/mdx

running it against /dev/sdx1 will make changes that unRAID will not see and thus not update parity properly.

I failed to wait for a response and ran a xfs_repair -vL against /dev/sdx1, which was prompted by the tool to do. 

 

I took the array offline and brought it back on and now my stuff is back, but have I broken my parity?

Yes, run a correcting parity check.
