  32 # DESCRIPTION:
  33 #       "Verify 'zpool resilver' restarts in-progress resilvers"
  34 #
  35 # STRATEGY:
  36 #       1. Write some data and detatch the first drive so it has resilver
  37 #          work to do
  38 #       2. Repeat the process with a second disk
  39 #       3. Reattach the drives, causing the second drive's resilver to be
  40 #          deferred
  41 #       4. Manually restart the resilver with all drives
  42 #
  43 # NOTES:
  44 #       Artificially limit the scrub speed by setting the zfs_scan_vdev_limit
  45 #       low and adding a 50ms zio delay in order to ensure that the resilver
  46 #       does not complete early.
