I'm guessing Linux will squawk and continue booting.Probably won't even squawk. IIRC, scanning for VGs is done during the boot process as long as you have LVM installed, whether you are using it or not.
But won't there be references to the non-existent vg in /etc/lvm that Debian uses during boot?
2. More importantly, what about when I power up the external enclosure, after Linux is already running? Will lvm automagically recognize the new drives as part of their own vg? Or will I have to bounce lvm?You *may* have to run 'vgscan && vgchange -ay', but that should be enough. Failing that, you might have to modify your lvm.conf, but that's only if lvm is, for some reason, not scanning those block devices for PV metadata.
Good enough... Thanks. -- Ron Johnson, Jr. Jefferson LA USA "Freedom is not a license for anarchy."
