# This test creates a RAID1, fails a disk, and immediately
# (simultaneously) creates a new array. This tests for a possible
# race where the meta data reflecting the disk failure may not
# be written when the 2nd array is created.

# 1) mdadm -C member1 fails - in this case the meta data
# was already on disk when the create attempt was made
# 2) mdadm -C succeeds in the first place (meta data not on disk yet),
# but mdmon detects the problem and sets the disk faulty.
