LVM getting stuck in containerized cinder-volume

[Jiří Stránský]

When trying to use LVM with udev-related capabilities in a cinder-volume container, all LVM calls gets stuck. This was the root cause of the infamous bug 1698136 that even prevented log collection from happening.

    LVM in cinder-volume container without udev

    Disabling udev usage from LVM seems to be the only observed working
    way of running containerized cinder-volume with local LVM backend.

    I didn't come across reports that not using udev would have negative
    impact on the functionality.
