LVM1 on-disk format: This limit is fixed by the Physical Extent size chosen when you create the Volume Group - see the vgcreate man page. It can't be changed later. LVM2 on-disk format: You should only be limited by the kernel's 2TB limit. So you would need to upgrade to LVM2 and use vgconvert to convert your metadata into the new format. [Note: (a) I've not tested this yet; (b) Certain LVM2 tool operations may appear slow as they are still (unnecessarily) proportional to the total number of physical extents in the VG and need optimising.] At some point we should have an LVM2 tool that changes the Physical Extent size.
