splitting a volume group

I just split a logical volume into two volumes.

I did this by using pvmove to move data around inside the volume group after adding more disks.
This left me with just 1 logical volume on a set of five physical volumes that I wanted to spit off from the others.

Note: I set physical volumes to non allocatable when using pvmove so that it moved them to the right place.

So, before I split, pvs looked something like this

PV         VG     Fmt  Attr PSize   PFree
/dev/md1   system lvm2 a-    44.92G   8.32G
/dev/md2   data   lvm2 --    93.75G  93.75G
/dev/md3   data   lvm2 --    93.75G  93.75G
/dev/md4   data   lvm2 --    93.75G  93.75G
/dev/md5   data   lvm2 --    93.75G  11.73G
/dev/md6   data   lvm2 a-    92.62G      0
/dev/md7   data   lvm2 a-   306.41G 212.67G
/dev/md8   data   lvm2 a-   306.41G 212.67G
/dev/md9   data   lvm2 a-   318.68G 213.21G

Then, I ran
vgchange -a n data
vgsplit -v data other /dev/md2 /dev/md3 /dev/md4 /dev/md5 /dev/md6
vgchange -a y data
vgchange -a y other

pvs then looked like

  PV         VG     Fmt  Attr PSize   PFree
  /dev/md1   system lvm2 a-    44.92G   8.32G
  /dev/md2   other  lvm2 --    93.75G  93.75G
  /dev/md3   other  lvm2 --    93.75G  93.75G
  /dev/md4   other  lvm2 --    93.75G  93.75G
  /dev/md5   other  lvm2 --    93.75G  11.73G
  /dev/md6   other  lvm2 a-    92.62G      0
  /dev/md7   data   lvm2 a-   306.41G 212.67G
  /dev/md8   data   lvm2 a-   306.41G 212.67G
  /dev/md9   data   lvm2 a-   318.68G 213.21G
