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

   Code Block
   language bash theme RDark
   df -h /data

   The system output should resemble the following:
   
   
   

2. Verify the new disk size:

   Code Block
   language bash theme RDark
   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
   language bash theme RDark
   fdisk /dev/sdc

   
   

   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 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 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)”

      
      

4. Reboot the system:
   

   Code Block
   language bash theme RDark
   reboot

   
   

5. When the system is available again, ensure the new partition is available:

   Code Block
   language bash theme RDark
   fdisk -l | grep /dev/sdc

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

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

7. Configure the new partition:

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

   
   

   Code Block
   language bash theme RDark
   pvcreate /dev/sdc2 vgextend vg_data /dev/sdc2 lvextend -l +100%FREE /dev/vg_data/lv_data

   
   

8. Identify the /data file system type (for CentOS 7.2+ based appliances the type is xfs):

   Code Block
   language bash theme RDark
   cat /etc/fstab | grep /data

   The system output should resemble the following:
   
   
   

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

   Code Block
   language bash theme RDark title For ext4
   resize2fs /dev/vg_data/lv_data

   
   

   Code Block
   language bash theme RDark title For xfs
   xfs_growfs /dev/vg_data/lv_data

   
   

   The system output should resemble the following:
   
   
   

10. Display the new size of the /data mount point:

    Code Block
    language bash theme RDark
    df -h /data

    
    

11. Update the Store configuration file (see below)using the Admin Console under Utilities → Store → Store Allocation.
12. Start all services using the Admin Console or app-util.sh.

Option 2: Adding an Additional Data Disk

...

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

   Code Block
   language bash theme RDark
   df -h /data

   The system output should resemble the following:
   

2. Identify the new disk:

   Code Block
   language bash theme RDark
   lsblk [ Note: Example output below is filtered to show only sdd disk information, but should include many more entries of sda, sdb and sdc disks ] NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdd 8:32 0 200G 0 disk

   
   

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

4. Execute the following commands. Replace the name of data disk if it is different in your environment.

   Code Block
   language bash theme RDark
   pvcreate -ff /dev/sdd vgextend vg_data /dev/sdd lvextend -l +100%FREE /dev/vg_data/lv_data

   
   

5. Identify the /data file system type (for CentOS 7.2+ based appliances the type is xfs): 

   Code Block
   language bash theme RDark
   cat /etc/fstab | grep /data

    The system output should resemble the following:
   
   
   

   
   

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

   Code Block
   language bash theme RDark title For ext4
   resize2fs /dev/vg_data/lv_data

   
   

   Code Block
   language bash theme RDark title For xfs
   xfs_growfs /dev/vg_data/lv_data

   
   The system output should resemble the following:
   
   
   

7. Display the new size of the /data mount point:

   Code Block
   language bash theme RDark
   df -h /data

   The system output should resemble the following:
   
   
   

8. Update the Store configuration file (see below).

Update the Store Configuration File

Execute the following script to update the Store configuration file with the new file system size:

Code Block
language bash theme RDark
/app/scripts/update_store_allocation.sh -l 1

Start the application by running
1. using the Admin Console under Utilities → Store → Store Allocation.
2. Start all services using the Admin Console or app-util.sh
 and selecting option 1 (start all)
3. .
