# DESCRIPTION:
# Trimming automatically resumes across offline/online.
#
# STRATEGY:
# 1. Create a pool with a two-way mirror.
# 2. Start trimming one of the disks and verify that trimming is active.
# 3. Offline the disk.
# 4. Online the disk.
# 5. Verify that trimming resumes and progress does not regress.
# 6. Suspend trimming.
# 7. Repeat steps 3-4 and verify that trimming does not resume.
#
