OK, so that's certainly a problem with pvscan not run from udev for nbd devices at proper time - we still need to fix this - we haven't covered this yet properly. It needs special treatment like we do in /lib/udev/rules.d/69-dm-lvm-metad.rules for MD and loop devs. The lvmetad running back - have you also disabled lvmetad in lvm.conf (use_lvmetad=0)? >> What is the lvm2 version in use here ? > > Where can I find this information? > Just run "lvm version" -- Peter _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
