[linux-lvm] striped lvm must have identical PV sizes?

[Vahid Pazirandeh <vpaziran yahoo com>]

hi all,

based on my experience below i'm guessing that all PVs included in a VG must be
identical in size if i want to stripe all of the PVs and take all of the VG
free space?  if so, is there a workaround so i can still write in parallel with
different PV sizes?  ala md-tools.

regards,
vahid
