I followed the procedure in the linked wiki, and after step 16, the data in shares on the formatted drive do not appear in those shares.
I copied disk22(swap) from disk21(old ReiserFS) and reassigned their drive numbers so now disk21(XFS former swap) and disk22(old ReiserFS)
now in /mnt/user/ShareName the data which should reside on disk21 does not appear but there is a /mnt/user/disk21 directory no other disk appears under /mnt/user
