I'm guessing this simply indicates that the kernel device name
associated with the PV has changed. Is that correct?
Jul 28 16:50:58 hostname lvm[1424]: PVID
6seLWa-Oz2d-jZIC-Ox17-MPaB-QGu5-uElsKN read from /dev/sdb1 last written
to /dev/sdd1.
No idea what this means. Should we be using quick activation? Is it a
result of the above?
Jul 28 16:50:58 hostname lvm[1424]: pvscan[1424] VG vg_leka not using
quick activation.
Thanks!

When the VG was last updated the PV was on sdd1, now it's on sdb1.

The activation of the VG from pvscan is not being optimized, because of
the device name change. That's not a problem, just informative.
Usually, I think these messages only appear in systemctl status for the
lvm2-pvscan service.
