[linux-lvm] lvm over iscsi

[Gordon McLellan]

Hello,

I'm guessing, from my own experiences with lvm, you'll have to either
export the bottom (the PV), or the top (the LV).   Trying to export
the middle puts it out of context.  A logical volume can't be detected
unless its physical volume is detected first (by the kernel?).

I wonder what pvcreate thinks of iscsi volumes.  could you create a pv
on an iscsi volume which is just an exported lv off another server?
