1. Add a big virtual disk to the UNetLab VM, I suggest at least 40GB.
2. Power on the VM:
fdisk -l | grep "contain a valid partition table"
3. Disk /dev/sdb
doesn’t contain a valid partition table. The new added disk is /dev/sdb
. Let’s configure it for LVM and expand the volume group:
4. Change partition type to 8e
echo -e "n\np\n1\n\n\n\t\n8e\nw\n" | fdisk /dev/sdb > /dev/null
5. Create physical volume
pvcreate /dev/sdb1
6. Extend the volume group rootvg
vgextend rootvg /dev/sdb1
7. If you want 10G only
lvextend -L +10G /dev/rootvg/rootvol
If you want all free space
lvextend -l 100%FREE /dev/rootvg/rootvol
8. The lv have done resize
resize2fs /dev/rootvg/rootvol
