Am I missing something here? vgchange --partial seems like it will do what you want (man 8 lvm): - -P | --partial When set, the tools will do their best to provide access to volume groups that are only partially available. Where part of a logical volume is missing, /dev/ioerror will be substituted, and you could use dmsetup (8) to set this up to return I/O errors when accessed, or create it as a large block device of nulls. Metadata may not be changed with this option. To insert a replacement physical volume of the same or large size use pvcreate -u to set the uuid to match the original followed by vgcfgrestore (8). You can also choose the device used for mapping segments on any incomplete logical volumes by setting the missing_stripe_filler parameter in the activation section of lvm.conf.
