Cloudera Manager root volume does not get resized

[#1]

After launching a new manager node I discovered the root volume was not resized to the provisioned limit.

# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 250G 0 disk
├─xvda1 202:1 0 200M 0 part /boot
├─xvda2 202:2 0 4G 0 part [SWAP]
└─xvda3 202:3 0 10.8G 0 part /

Fixed by picking a different AMI, the original AMI had multiple partitions on the root disk which the director install did not appreciate. Switching to an AMI with a single partition on the root volume appears to have resolved this issue entirely. FWIW the picking the official centos AMI should ensure you dont have a bad time.
