Comment 16 for bug 1817097

Decreasing importance from critical to medium, because the bug is known to the community, it is already discussed in RH Bug 1669751, and here https://www.redhat.com/archives/linux-lvm/2019-February/msg00018.html / https://www.redhat.com/archives/linux-lvm/2019-March/msg00000.html, and not platform specific, nor specific to a certain Ubuntu release.
On top there are actions possible to easily avoid this situation, like explicitly setting / forcing the sector size to be 4096 bytes or using a bigger image size (>512 MB - which is not uncommon), so that the sector size default changes to 4k anyway.
A patch was already suggested upstream:
https://sourceware.org/git/?p=lvm2.git;a=commit;h=dd6ff9e3a75801fc5c6166aa0983fa8df098e91a
Once that patch got upstream accepted and became picked-up in a new lvm2 version, it will eventually land in Ubuntu, too.
