[Gllug] I've lost my RAID partition in to the ether.....

[Andy Farnsworth]

Nick,
  You have probably tried this, but just unmount the RAID and check the
mount point.  You might have never actually mounted the RAID before and just
been writing to a different drive altogether.

Thanks for responding Doug

I checked the logs but there appeared to be no errors with the RAID, and if
I cat /proc/mdstat everything looks normal.

Neither disk when mounted independently has my data on. However, what is
wierd is that the disks appear to have different data on. Even if I had my
data I would expect the junk thats left to be mirrored.

Is there any other way of checking to see if the RAID is functioning
correctly?

If mirroring was not on how would the disks sync if mirroring was turned on.
(Which way would data get copied?)

Nick
