Hi,

filing this issue with severity RC to prevent testing migration.

It appears the new LVM release breaks both systemd and multipath-tools's
autopkgtest suite

https://ci.debian.net/packages/m/multipath-tools/testing/amd64/43382441/
https://github.com/systemd/systemd/issues/31517

Hi
to be a result of
https://salsa.debian.org/linux-blocks-team/multipath-tools/-/blob/master/debian/patches/0002-11-dm-mpath-fix-DM_UDEV_RULES_VSN-check.patch?ref_type=heads
So far this patch had been necessary, since lvm2 itself had modified the
udev rules downstream, but no longer does that thankfully with the
latest update.
See the remarks in
https://github.com/systemd/systemd/issues/31517#issuecomment-1971788035

Chris updated multipath-tools accordingly:
https://salsa.debian.org/linux-blocks-team/multipath-tools/-/commit/902a13b2c628d2cfde74cb78fd1ba4425af3d7d4
and uploaded it as 0.9.7-6. With that, multipath-tools and systemd's
autopkgtest are unbroken again.

I'm still keeping the bug report open, as you might consider adding a
versioned breaks against multipath-tools to dmsetup.
Downgrading to non-RC now though.

Regards,
Michael
