  21 # DESCRIPTION:
  22 #       Attempt to take a checkpoint while a removal is
  23 #       in progress. The attempt should fail.
  24 #
  25 # STRATEGY:
  26 #       1. Create pool with one disk
  27 #       2. Create a big file in the pool, so when the disk
  28 #          is later removed, it will give us enough of a
  29 #          time window to attempt the checkpoint while the
  30 #          removal takes place
  31 #       3. Add a second disk where all the data will be moved
  32 #          to when the first disk will be removed.
  33 #       4. Start removal of first disk
  34 #       5. Attempt to checkpoint (attempt should fail)
