I believe it can be a bit challenging for ubuntu users to introduce recheck_wwid parameter. What I checked already, this parameter is available for multipath-tools, but the package which provides it is on-board with ubuntu 22.04LTS. Older ubuntu releases do not have this possibility and gives an error:
/etc/multipath.conf line XX, invalid keyword: recheck_wwid

I made such assumption based on release documentation:
- for ubuntu 20.04: https://manpages.ubuntu.com/manpages/focal/en/man5/multipath.conf.5.html
- for ubuntu 22.04: https://manpages.ubuntu.com/manpages/jammy/en/man5/multipath.conf.5.html

So it seems that partially Yoga, but fully Zed OS release can take such parameter directly, but older releases should manage such change differently.

I know that OpenStack code is independent of linux distros, but just wanted to add this info here, as worth to consider.
