[linux-lvm] bogus WARNING: Device for PV not found or rejected by a filter.

[Chris Murphy]

Fedora 27 Server:
4.14.16-300.fc27.x86_64
lvm2-2.02.175-1.fc27.x86_64

Every 10 or so minutes in the journal, I'm getting what appears to be
a bogus warning. I say bogus because the PV is present, and I can
mount an XFS formatted LV found on this PV without error.

Decoder ring:
/dev/sdb is the relevant HDD in a USB enclosure
/dev/sdb1 is the only partition on it, LUKS
/dev/mapper/sdb is the unlocked LUKS device, which is also the PV in
question, and the only PV in the VG named "4vg"
