Bug Description

Brief Description
-----------------
In some labs with certain disk types it has been observed that the root disk is not aligned. This leads to disk performance issues severe enough to cause software failures and timeouts.

Severity
--------
Critical for systems that see the issue (only 1 system observed to date)

Steps to Reproduce
------------------
Install STX load on a controller.
Check the following command:
sudo parted /dev/sda align-check optimal 1

Expected Behavior
------------------
Result of above command should be "aligned"

Actual Behavior
----------------
Result of above command is not aligned
Also disk operations are significantly degraded

Reproducibility
---------------
Seen on one system, 100% reproducible on that system

System Configuration
--------------------
Could occur on any config

Branch/Pull Time/Commit
-----------------------
System is using an STX4.0 load from May 2020.

Last Pass
---------
n/a - only seen on this one system to date with the specific disk in that system

Timestamp/Logs
--------------
n/a

Test Activity
-------------
Initial install and commissioning.

Workaround
----------

This issue is not seen recently and was only reported the one time. If the frequency of this issue increases then a new LP will be opened with a recent load.

    Add /pxeboot/grubx64.efi symlink for UEFI pxeboot

    UEFI pxeboot with shim.efi looks for the grubx64.efi in the tftpboot
    root directory. This update creates a symlink to the
    /pxeboot/EFI/grubx64.efi file in /pxeboot.

    Fix enabling heartbeat of self from the peer controller

    This issue only occurs over an hbsAgent process restart
    where the ready event response does not include the
    heartbeat start of the peer controller.

    This update reverts a small code change that was
    introduced by the following update.

    https://review.opendev.org/c/starlingx/metal/+/788495

    Remove the my_hostname gate introduced at line 1267 of
    mtcCtrlMsg.cpp because it prevents enabling heartbeat
    of self by the peer controller.

    Improved maintenance handling of spontaneous active controller reboot

    Performing a forced reboot of the active controller sometimes
    results in a second reboot of that controller. The cause of the
    second reboot was due to its reported uptime in the first mtcAlive
    message, following the reboot, as greater than 10 minutes.

    Maintenance has a long standing graceful recovery threshold of
    10 minutes. Meaning that if a host looses heartbeat and enters
    Graceful Recovery, if the uptime value extracted from the first
    mtcAlive message following the recovery of that host exceeds 10
    minutes, then maintenance interprets that the host did not reboot.
    If a host goes absent for longer than this threshold then for
    reasons not limited to security, maintenance declares the host
    as 'failed' and force re-enables it through a reboot.

    With the introduction of containers and addition of new features
    over the last few releases, boot times on some servers are
    approaching the 10 minute threshold an...
