[PVE-User] LVM autoactivation failed with multipath over iSCSI

After upgrading a node that uses iSCSI multipath to 6.1, auto activation of LVM volumes fails for me as well.
I am seeing exactly the same problem as originally reported by Nada.

Apparently, LVM scans the iSCSI adapters before multipath is fully loaded and consequently ignores volumes appearing on duplicate devices.
Marco Gaiarin correctly noted this in January.

See the error messages in the system log below.

Does anyone have a hint, how to delay the lvm-pvscan service until multipath has finished its discovery?

Thanks

Stefan
