To create the new volume group
yourvg, use the
vgsplit command to split the volume group
Before you can split the volume group, the logical volume must be inactive. If the file system is mounted, you must unmount the file system before deactivating the logical volume.
You can deactivate the logical volumes with the
lvchange command or the
vgchange command. The following command deactivates the logical volume
mylv and then splits the volume group
yourvg from the volume group
myvg, moving the physical volume
/dev/sdc1 into the new volume group
lvchange -a n /dev/myvg/mylv
vgsplit myvg yourvg /dev/sdc1
Volume group "yourvg" successfully split from "myvg"
You can use the
vgs command to see the attributes of the two volume groups.
