# DESCRIPTION:
|
|
# Check various pool geometries stripe, mirror, raidz)
|
|
#
|
|
# STRATEGY:
|
|
# 1. Create a pool on file vdevs to trim.
|
|
# 2. Set 'autotrim=on' on pool.
|
|
# 3. Fill the pool to a known percentage of capacity.
|
|
# 4. Verify the vdevs contain 75% or more allocated blocks.
|
|
# 5. Remove all files making it possible to trim the entire pool.
|
|
# 6. Wait for auto trim to issue trim IOs for the free blocks.
|
|
# 7. Verify the disks contain 30% or less allocated blocks.
|
|
# 8. Repeat for test for striped, mirrored, and RAIDZ pools.
