# Description:
# Verify that on import an in progress attach operation is resumed.
#
# Strategy:
# 1. For both healing and sequential resilvering.
#    a. Create a pool
#    b. Add a vdev with 'zpool attach' and resilver (-s) it.
#    c. Export the pool
#    d. Import the pool
#    e. Verify the 'zpool attach' resumed resilvering
#    f. Destroy the pool
