Patrick, thanks for responding,

pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ACTIVE   PV "/dev/hdb2" of VG "vg0" [4.75 GB / 44 MB free]
pvscan -- ACTIVE   PV "/dev/hdd2" of VG "vg0" [9.49 GB / 4.78 GB free]
pvscan -- total: 2 [14.25 GB] / in use: 2 [14.25 GB] / in no VG: 0 [0]

Since I only have 44 MB free on hdb2, is that the size limit of any new
additional striped volumes I can create? 

Can I create unstriped volumes with the balance of the space left on the
volume group?

Can I resize existing striped volumes and make them larger, and if yes, am
I limited to a maximum of 44MB as shown by pvscan?
