My unix skills are very basic so please bare with me.

I have a VirtualBox Linux Guest (Oracle Enterprise Linux 6) and I recently expanded hard drive from 50Gb to 100Gb and then used GParted to resize to use the newly added 50GB (as this was unallocated). All this was successful but then I came across the error "No free sectors available"

Please can someone kindly provide steps which will allow me to expand and use the full 100GB.

Any help / advise would be greatly appreciated.

Many thanks

If you want to create new partition you may use lvcreate instead of fdisk /dev/sda. Follow the bellow step in command line

Step 1:

 # lvcreate --name lvname --size lvsize vgname
 # ex lvcreate --name lv_home --size 30G vg_oralab1

Step 2: Format the Logical volume(lv) by any linux filesystem

 # mkfs.xfs /dev/vg_oralab1/lv_home

Step 3: Create mount point and mount the lv

# mkdir /lv_part
# mount /dev/vg_oralab1/lv_home /lv_part

Step 4: Check the partition by

# df -h

NOTE: For permanent mount give entry in /etc/fstab

you already have all the disk at sda2, as I can see at pvs command (size 99Gb, 50GB free)

So you only have to increased the lvs partition that already have.

lvextend -l +100%FREE /dev/mapper/vg_oralab1-lv_root

and resize at os level:

resize2fs /dev/mapper/vg_oralab1-lv_root

now you are using all the size in your lvm filesystem.
