Read the manpage. 2. You can specify a destination or destinations if you like. You can also limit the source to a single LV. 3.

There is no lvmove or vgmove, nor is there a need for them. Moving a VG to different physical media is handled via pvmove. Moving a LV to different physical media is handled via pvmove. Moving a PV to different phyical media doesn't make sense (usually) and is NOT handled via pvmove. If you have a VG that is on /dev/sda2 and /dev/sdb and you want to move it (and, of course, all the LVs it contains) to /dev/sdc1, /dev/sdc2, /dev/sdc3, and /dev/sdc4, you do: pvcreate /dev/sdc1 pvcreate /dev/sdc2 pvcreate /dev/sdc3 pvcreate /dev/sdc4 vgextend $vg /dev/sdc1 vgextend $vg /dev/sdc2 vgextend $vg /dev/sdc3 vgextend $vg /dev/sdc4 pvmove /dev/sda2 pvmove /dev/sdb vgreduce $vg /dev/sda2 vgreduce $vg /dev/sdb pvremove /dev/sda2 pvremove /dev/sdb If your VG contains /dev/md1, a RAID-0 device, and /dev/sdb, a hardware RAID-6 device, and part of LV "home" was allocated to /dev/md1 accidentally or temporarily you can move that data to /dev/sdb with: pvmove /dev/md1 -n home /dev/sdb -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
