# DESCRIPTION:
# Testing Fault Management Agent ZED Logic - Automated Auto-Spare Test when
# drive is faulted and a custom ashift value needs to be provided to replace it.
#
# STRATEGY:
# 1. Create a pool from 512b devices and set "ashift" pool property accordingly
# 2. Add one 512e spare device (4Kn would generate IO errors on replace)
# 3. Inject IO errors with a zinject error handler
# 4. Start a scrub
# 5. Verify the ZED kicks in the hot spare and expected pool/device status
# 6. Clear the fault
# 7. Verify the hot spare is available and expected pool/device status
#
