|
# DESCRIPTION:
|
|
# Sequential reconstruction (unlike healing reconstruction) operate on the
|
|
# top-level vdev. This means that a sequential resilver operation can be
|
|
# started/stopped on a different top-level vdev without impacting other
|
|
# sequential resilvers.
|
|
#
|
|
# STRATEGY:
|
|
# 1. Create a mirrored pool.
