I had three drives in LVM: a 2 TB drive and two 1 TB drives (added later). One of the 1 TB drives -- I believe the third one -- has died. Spanning all three drives was an XFS partition.

Reading: http://www.novell.com/coolsolutions/appnote/19386.html I see that one way of handling this is to replace the dead drive and copy the metadata over. However, I am currently not in possession of a 1 TB drive and can not readily acquire one.

Given this, what are my options? There was nothing important on the drives (if there was I would have them in RAID 1) but I would not mind attempting a recovery. Is there a simple way of forcing LVM to go with just two drives and NUL out anything else? (So that fsck can do its thing.)
