  25. # DESCRIPTION:
    26. 

  26. #
    27. 

  27. # When a pool has an ongoing removal and it is exported ZFS
    28. 

  28. # suspends the removal thread beforehand. This test ensures
    29. 

  29. # that ZFS restarts the removal thread if the export fails
    30. 

  30. # for some reason.
    31. 

  31. #
    32. 

  32. # STRATEGY:
    33. 

  33. #
    34. 

  34. # 1. Create a pool with one vdev and do some writes on it.
    35. 

  35. # 2. Add a new vdev to the pool and start the removal of
    36. 

  36. #    the first vdev.
    37. 

  37. # 3. Inject a fault in the pool and attempt to export (it
    38. 

  38. #    should fail).
    39. 

  39. # 4. After the export fails ensure that the removal thread
    40. 

  40. #    was restarted and the process complete successfully.
    41.
