hu_disks

Actual disks which are available on this node

It is a list of dicts which are formatted other way than ks_spaces disks. To match both of those formats use _match_device method.

bareon.drivers.data.nailgun.match_device(hu_disk, ks_disk)

Check if hu_disk and ks_disk are the same device

Tries to figure out if hu_disk got from hu.list_block_devices and ks_spaces_disk given correspond to the same disk device. This is the simplified version of hu.match_device

Parameters:hu_disk – A dict representing disk device how

it is given by list_block_devices method. :param ks_disk: A dict representing disk device according to

ks_spaces format.

Returns:True if hu_disk matches ks_spaces_disk else False.
