Foreign Drives
Hello. Our server crashed on 12th October, it was RAID10 but now 2 disc's display Foreign. Can I rebuild the RAID or will I lose all the data. Its no big problem as this is a second server that acts as a replication machine. Thanks

So considering they are each a part of a different mirrored pair you have two options to approach here. You could attempt to import the foreign configs and allow the foreign drives to attempt to rebuild, that being said the fact that they went foreign in the first place tells me there is a good chance there might be something wrong with those two drives so it's not out of the norm for them to go foreign again or just outright fail.
The other option would be to just replace those drives and let the array rebuild onto the two replaced drives and at that point the array should be good and optimal at that point.
Given that this is a raid 10 the data should all still be there and good as long as the other drive in the mirrored pair doesn't fail out.
