26# DESCRIPTION:
27# Trimming automatically resumes across offline/online.
28#
29# STRATEGY:
30# 1. Create a pool with a two-way mirror, prepare blocks to trim.
31# 2. Start trimming one of the disks and verify that trimming is active.
32# 3. Offline the disk.
33# 4. Online the disk.
34# 5. Verify that trimming resumes and progress does not regress.
35# 6. Suspend trimming.
36# 7. Repeat steps 3-4 and verify that trimming does not resume.
