Volume group "yourvg" successfully split from "myvg"

You can use the vgs command to see the attributes of the two volume groups.

[root@tng3-1 ~]# vgs

VG #PV #LV #SN Attr VSize VFree

myvg 2 1 0 wz--n- 34.30G 10.80G

yourvg 1 0 0 wz--n- 17.15G 17.15G

5.3.4. Creating the New Logical Volume

After creating the new volume group, you can create the new logical volume yourlv.

[root@tng3-1 ~]# lvcreate -L5G -n yourlv yourvg

Logical volume "yourlv" created

You can make a file system on the new logical volume and mount it.

[root@tng3-1 ~]# mkfs.gfs2 -plock_nolock -j 1 /dev/yourvg/yourlv

[root@tng3-1 ~]# mount /dev/myvg/mylv /mnt

[root@tng3-1 ~]# df
