26# DESCRIPTION:
27# Testing Fault Management Agent ZED Logic - Automated Auto-Spare Test when
28# drive is faulted due to IO ERRORS.
29#
30# STRATEGY:
31# 1. Create a pool with hot spares
32# 2. Create a filesystem with the primary cache disable to force reads
33# 3. Write a file to the pool to be read back
34# 4. Inject IO ERRORS on read with a zinject error handler
35# 5. Verify the ZED kicks in a hot spare and expected pool/device status
36# 6. Clear the fault
37# 7. Verify the hot spare is available and expected pool/device status
38#
