What's the benefit of doing that (assuming just one member of the ccd) ? If the object /dev/mapper/vg0-lvpbulk works for gpt, and ccd, then isn't that already a device, at least for most practical purposes ? Wouldn't (if needed, that is, if it doesn't happen already) dkctl /dev/mapper/vg0-lvpbulk makewedges work to access the partitions inside a LV containing GPT partitioning? Note, I know nothing at all about LVM, treat all of this as questions from a curious bystander.
Unfortunately, no - the lvm devices (similar to zvols in the ZFS world) don't support the necessary ioctls: # dkctl /dev/mapper/rvg0-ubnt makewedges dkctl: /dev/mapper/rvg0-ubnt: makewedges: Inappropriate ioctl for device I agree that it would probably be more useful if they did, but here we are. +j
