at the OS level

1. Verify the current size of mount point /data:

   Code Block
   df -h /data

   The system output should resemble the following:
   Image Modified

2. Verify the new disk size:

   Code Block
   fdisk -l |grep /dev/sdc

   The system output should resemble the following:

   

3. Use fdisk to create a new partition for the new size:

   Code Block
   fdisk /dev/sdc

    and perform the following steps:

   1. Press p to print the partition table to identify the number of partitions:
      
      If this is the first time the disk is extended, you should only see sdc1. If this is a subsequent extension - you will see additional sdcX listed (e.g. sdc2 for the second extension)
   2. Press n to create a new primary partition.
   3. Press p for primary.
   4. When the system prompts for a partition number, enter the next number depending on the output of the partition table print.
      If this is the first extension and you see only one row of output - enter 1 2. If this is the second disk extension then the partition number will be 3, and so on.
   5. Press Enter twice
      
   6. Press t to change the system's partition ID.
   7. Press 2 to select the newly creation partition.created partition (Remember: if this is a subsequent disk extension - the number will be 3 or higher)
   8. Type 8e to change the Hex Code of the partition for Linux LVM.

   9. Press w to write the changes to the partition table.
      
      
      
      

      Note
      the following warning is valid, the system reboot will fix the issue : “WARNING: Re-reading the partition table failed with error 16: Device or resource busy.The kernel still uses the old table. The new table will be used at the next reboot or after you run partprobe(8) or kpartx(8)”

      
      

   10. Reboot the system:

       Code Block
       reboot

       
       

   11. When the system is back up, ensure the new partition is available:

       Code Block
       fdisk -l | grep /dev/sdc

       The system output should resemble the following (note the new sdcX added)
       Image Modified

   12. Stop the application by running app-util.sh and selecting option 2 (stop all)

       Note
       If the new partition is not sdc2, substitute sdc2 for the right qualifier in all the following commands

       
       

   13. Create a new LVM Physical Volume (PV):

       Code Block
       pvcreate /dev/sdc2

       
       

   14.  Extend the LVM Volume Group (VG):

       Code Block
       vgextend vg_data /dev/sdc2

       
       

   15. Extend the LVM Logical Volume (LV):

       Code Block
       lvextend -l +100%FREE /dev/vg_data/lv_data

       
       

   16.  Identify the /data file system type (for CentOS 7.2 based appliance the type is xfs):

       Code Block
       cat /etc/fstab |grep /data

       The system output should resemble the following:
       Image Modified

   17.  Resize the file system. Select the correct command below for your file system type:

       Code Block
       title ext4
       resize2fs /dev/vg_data/lv_data

       
       

       Code Block
       title xfs
       xfs_growfs /dev/vg_data/lv_data

       The system output should resemble the following:
       Image Modified

   18. To display the new size of the /data mount point:

       Code Block
       df -h /data
