Extend volume group with adjacent unallocated space

Solution 1:

1. fdisk to create a new partition #7 containing the space after sda6
2. reboot to ensure that all partitions are registered properly and the device names are created.
3. pvcreate /dev/sda7
4. vgextend [volumegroupname] /dev/sda7
5. vgdisplay -v [volumegroupname] ;; to see the added size and # extents

Now more space is contained in volumegroup.

I presume that you are extending one of the logical volumes within the VG that already contains an ext2/ext3 filesystem. For safety I'd suggest unmounting the logical volume that you want to expand.

5. lvextend -l +[numberextentsfreefrom#5] [logicalvolumepath]
6. resize2fs [logicalvolumepath]

Your logicalvolumepath will now have more available space.
