Hi,
the updated Amazon Web Service AMI (ami-4ac6653d) has a serious bug. It is not possible to resize a disk after creating a new volume with a size greater than 8GB.
resize2fs does nothing.
The previous AMI worked perfectly but is no longer available. This bug is a show stopper for using CentOS on AWS.
Regards, Thorsten
PS: It would also be great to have a CentOS 6 AMI with HVM virtualisation.
