lvm broke multipath on provisioned systems

[Aleksey Zvyagintsev]

Input:
System with multipath disks

Summary:
Provision process finished successfully, provisioned system up and running, but multipath does not work on it at all.
Output from 'multipath -ll' is empty. List of physical volumes in LVM shows that LVM grubs physical devices instead of devmapper's devices. As a result multipath can not assemble MP devices.

is it related with lvm.conf filters ?

    Add LVM filters and preferred_names into LVM config

    If we have some multipath block devices on the node, we need
    to prevent LVM from grubbing multipath underlying devices during boot into
    target OS. To achieve it, we have to whitelist in LVM filters all
    non-multipath devices from /dev/disk/by-id dir and force LVM to scan
    /dev/mapper dir for volume groups on multipath devices
