# DESCRIPTION:
# Cancelling and suspending trim doesn't work if not all specified vdevs
# are being trimmed.
#
# STRATEGY:
# 1. Create a three-disk pool.
# 2. Start trimming and verify that trimming is active.
# 3. Try to cancel and suspend trimming on the non-trimming disks.
# 4. Try to re-trim the currently trimming disk.
