Hi Jackie,  I'm betting the issue is the second block device is /dev/sdb rather than /dev/vda.  Check to see what it actually shows up as under your virtualization environment and then make sure the "ecs_block_devices:" lists only contain valid block devices.  For example, change this:      ecs_block_devices:       - /dev/vda  To this:      ecs_block_devices:       - /dev/sdb  Let me know if that resolves the issue.  Thanks!

I finished the pre-configuration by referring to [URL] ran $ step1... Then it kept complaining that there was no available block storage even though the size of hard disk 2 was 104 GB. [IMAGE] This CE is just killing me as I got too many errors while running the command step1.  I've even tried to use thick vmdk and increased the size to 150GB but still no luck.  The same error message persists anyway.  I've tried to search by using Google but unfortunately no such information could be found.   The related install.log and deploy.yml files are attached at here.   I'm appreciated if anyone could figure out what's exactly happening with this issue. Thanks.
