#
# DESCRIPTION:
#   Turning both disks offline should fail.
#
# STRATEGY:
#   1. Create a multidisk stripe and start some random I/O
#   2. For two disks in the stripe, set them offline sequentially.
#   3. Zpool offline should fail in both cases.
#   4. Verify the integrity of the file system and the resilvering.
