Bug 2037955

*** Bug 2033737 has been marked as a duplicate of this bug. ***

To quote Brian Stinson:

It seems that we're missing this to support mdraid layouts made by the
installer. Do we have a plan to get this in as a Blocker/Exception? or
do we have some documentation prepared for customers who might want to
use mdraid devices for 9.0GA?

Prepared and pre-verified: https://github.com/redhat-plumbers/dracut-rhel9/pull/22

I've prepared a Draft PR, which includes scratch-builds:

Hello,

we see new messages

dracut-initqueue:   WARNING: File locking is disabled.
dracut-initqueue:   Configuration node devices/global_filter not found
dracut-initqueue:   Configuration node devices/filter not found

in journal. Can we assume these are direct result of changes made for this bugzilla and expected?

Thank you,

Jan

This is expected, a result of of using --nolocking.  (I'll probably suppress that message from lvm commands in the next release.)

> dracut-initqueue:   Configuration node devices/global_filter not found
> dracut-initqueue:   Configuration node devices/filter not found

These are expected from the two "lvm config" commands.  I didn't realize these would be logged in the journal, so I'll find a way to suppress these in the next release.

Yes, these are from the recent dracut lvm changes.

Great, thanks for the confirmation.

Changing this in lvm would require a new option, so a simpler solution is this patch which I'll send upstream:
