Yes, it just causes lvm to skip the use of /etc/multipath/wwids for
checking if a device is a multipath component.

Thanks. I'm still not happy about it, but if we find no other solution,
I guess it will be ok.

Could you try multipath_wwids_file="" and see if that's sufficient before
we add a new setting that's nearly the same?


I did some test.
1. multipath_wwids_file="" failed boot if without commit 17a3585cbb55d9a15
   So empty value is not enough, or some code logic changed which makes lvm2
   denying multipath dev.
2. using system.devices, machine could boot successfully.

Thanks,
Heming
