I converted my meta data to LVM2 :

#vgdisplay
  --- Volume group ---
  VG Name               main
  System ID             PV_IMPTuX1061637595
  Format                lvm2
  Metadata Areas        2
  Metadata Sequence No  1
  VG Access             read/write
  VG Status             resizable
  MAX LV                256
  Cur LV                3
  Open LV               3
  Max PV                256
  Cur PV                2
  Act PV                2
  VG Size               49.41 GB
  PE Size               32.00 MB
  Total PE              1581
  Alloc PE / Size       1256 / 39.25 GB
  Free  PE / Size       325 / 10.16 GB
  VG UUID               3PL6Zl-KtFh-pOqH-ntf5-C5td-SPxt-uUFZqJ

#pvdisplay
  Physical volume "/dev/hda5" of volume group "main" is exported
  --- Physical volume ---
  PV Name               /dev/hda5
  VG Name               main (exported)
  PV Size               31.25 GB / not usable 0
  Allocatable           yes (but full)
  PE Size (KByte)       32768
  Total PE              1000
  Free PE               0
  Allocated PE          1000
  PV UUID               Kyk15O-llcC-IVcO-VnhM-gDbZ-DlPd-UXABpn

  Physical volume "/dev/hdb5" of volume group "main" is exported
  --- Physical volume ---
  PV Name               /dev/hdb5
  VG Name               main (exported)
  PV Size               18.16 GB / not usable 0
  Allocatable           yes
  PE Size (KByte)       32768
  Total PE              581
  Free PE               325
  Allocated PE          256
  PV UUID               ELffaP-gavW-bMJA-Nx6K-qFqi-eDsk-Pwq3jL

But is still not work :

#lvcreate -i2 -I4 -L1G -n main/lv_usr
  Insufficient allocatable extents suitable for striping for logical
volume lv_usr: 32 required

How can I move one logical volume from /dev/hda5 to /dev/hdb5 ?

Thanks a lot.
