# Description:
|
|
# Verify that attach/detach work while resilvering and attaching
|
|
# multiple vdevs.
|
|
#
|
|
# Strategy:
|
|
# 1. Create a single vdev pool
|
|
# 2. While healing or sequential resilvering:
|
|
# a. Attach a vdev to convert the pool to a mirror.
|
|
# b. Attach a vdev to convert the pool to a 3-way mirror.
|
|
# c. Verify the original vdev cannot be removed (no redundant copies)
|
|
# d. Detach a vdev. Healing and sequential resilver remain running.
|
|
# e. Detach a vdev. Healing resilver remains running, sequential
|
|
# resilver is canceled.
|
|
# f. Wait for resilver to complete.
