shrinking a container on PERC 3/Di

[Grzegorz Sójka]

I'm using PowerEdge4400 equiped with PERC 3/Di ROMB. I was trying to
shrink an existing container:

3    Stripe 23.8GB       32KB Valid
 /dev/sdd             home
  57  Mirror 7.93GB                    0:00:0  553MB:7.93GB
                                       0:01:0  553MB:7.93GB
  56  Mirror 7.93GB                    0:02:0  553MB:7.93GB
                                       0:03:0  553MB:7.93GB
  55  Mirror 7.93GB                    0:05:0  553MB:7.93GB
                                       0:04:0  553MB:7.93GB

Using the command (I'm afacli fan):

container reconfigure /partition_size=7680M 3

but I'm getting following error message:

Executing: container reconfigure /partition_size=8,053,063,680  3
Command Error: <The reconfigure operation failed because the new
container size was too small.>

What is the problem? Is it possible to shrink an existing container
without deleting it?

Best regards
