Error : "KeyError: u'/dev/sda1'" on CentOS

[Nicolas G]

Hello,

I have setup Aminator on a CentOS image and trying to use it on one of our private AMIs running the bellow command but I get some sort of mount problems if my understanding about the error is correct :

aminate -e ec2_yum_linux -B ami-0a5bb47d --debug

See the debug output in gist -> https://gist.github.com/nicolas-g/8240095 

Some more info about the Aminator server system :

mount

/dev/xvde on / type ext4 (rw)

proc on /proc type proc (rw)

devpts on /dev/pts type devpts (rw,gid=5,mode=620)

tmpfs on /dev/shm type tmpfs (rw)

/dev/xvdf on /mnt type ext4 (rw)

none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)

python --version

Python 2.6.6

Any ideas ?

Kind regards,

Nicolas.

Nicolas,

The AMI doesn't include a block device mapping for the device identified by the AMI's root device name (/dev/sda1). I'm guessing that the image has a partition table but Aminator only supports partition-less images. 

See: https://github.com/Netflix/aminator/issues/59 for more background on this issue.
