# DESCRIPTION:
# Spare devices (both files and disks) can be shared among different ZFS pools.
#
# STRATEGY:
# 1. Create two pools
# 2. Add the same spare device to different pools
# 3. Inject IO errors with a zinject error handler
# 4. Start a scrub
# 5. Verify the ZED kicks in a hot spare and check pool/device status
# 6. Clear the fault
# 7. Verify the hot spare is available and check pool/device status
#

# NOTE: must be larger than other "file" vdevs and minimum SPA devsize:
