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)
