[linux-lvm] (simple question) Is it possible to specify a size to extend an LVM partition to ? rather than the amount to increase by?

Try:

--size 10G

      -L, --size [+]LogicalVolumeSize[bBsSkKmMgGtTpPeE]
              Extend  or set the logical volume size in units of megabytes.  A
              size suffix of M for megabytes, G  for  gigabytes,  T  for  ter‐
              abytes, P for petabytes or E for exabytes is optional.  With the
              + sign the value is added to the actual size of the logical vol‐
              ume and without it, the value is taken as an absolute one.
