An issue with the OpenStack Platform director 7.2 ramdisk and kernel image caused provisioning failure with the following error:
mount: you must specify the filesystem type
Failed to mount root partition /dev/sda on /mnt/rootfs
This update reverts the ramdisk and kernel image to the OpenStack Platform director 7.1 images. Using these images, the director now provisions Overcloud nodes without failure.
NOTE: An alternative workaround is to disable localboot option for the different node types. For example, to disable localboot with Controller nodes, run:
$ nova flavor-key control unset capabilities:boot_option
