Software RAID: Get component devices by md UUID

2020-09-29T15:08:40+00:00

Scanning the output of mdadm commands for RAID members will
miss component devices which are currently not part of the
RAID. For proper cleaning it is better to scan block devices
for a signature of the md device for which we would like to
get the components.

Software RAID: Don't delete partitions too early

2020-09-28T08:35:12+00:00

Partions on the holder disk should only be deleted after
all RAID devices have been deleted. Otherwise, super blocks
on partitions which reside on the same disks cannot be cleaned.

Fix backup node lookup

2020-09-09T22:19:38+00:00

The node lookup code added in change
I27201319f31cdc01605a3c5ae9ef4b4218e4a3f6
was slightly broken in that we call a method
with a keyword arguemnt which doesn't exist.

uuid versus node_uuid.

It happens, it is a quick fix!

Spotted on a metalsmith job:

[-] Agent is requesting to perform an explicit node cache update.
    This is to pickup any chanages in the cache before deployment.
[-] Failed to update node cache. Error lookup_node() got an
    unexpected keyword argument 'uuid'

Update the cache if we don't have a root device hint

2020-08-25T19:34:48+00:00

Or at least try to.

Some deployments just don't use root device hints, and this is okay.

However, other deployments need root device hints, and with fast
track mode in ramdisks, we created a situation where the node cache
could be updated by a human or software between the time the agent
was started, and the deployment was requested.

As a result, the agent has been updated to check if we have a hint
and if we don't, update the cache from the node lookup endpoint.

This is not needed when the inband deploy steps are executed, as
the process of updating the steps does force the node cache to be
updated.

Return the final RAID configuration from apply_configuration

2020-07-29T08:10:18+00:00

AgentRAID expects it and fails with TypeError if it's not provided.

Fix bootloader install issue with MDRAID

2020-07-22T18:16:13+00:00

When no root_device hint is set, an MDRAID partition can be incorrectly
selected as the root device which causes installation of the bootloader
to the physical disks behind the MDRAID volume to fail. See the notes
in the referenced Story for more detail.

This change adds a little more specificity to the listing of block
devices.

Ignore devices with size 0 when collecting inventory

delete_configuration still fetches all devices as it needs to clean
ones with broken RAID.
