Increase the Data Disk and File System

...

There are two strategies for increasing the disk space for the DPODs Store  

• Extend the existing data hard drive
• Add new data hard drive

• • Display the current size of mount point / data : df -h /data
    
    
    
    
  • Display the new disk size : fdisk -l |grep /dev/sdc
    
    
    
    
  • Create new partition for the new size :
    • fdisk /dev/sdc
    • Press p to print the partition table to identify the number of partitions.
      If this is the first disk extending there should be only sdc1. If this is the second time there should be sdc1 and sdc2.
      
      
      
      
    • Press n to create a new primary partition.
    • Press p for primary.
    • Press 2 for the partition number, depending on the output of the partition table print (if this is the second disk extending then the partition number will be 3 )
    • Press Enter two times.
      
      
      
      
    • Press t to change the system's partition ID.
    • Press 2 to select the newly creation partition.
    • Type 8e to change the Hex Code of the partition for Linux LVM.

    • 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)”

      
      
      

    • Reboot the system : reboot
    • After the system is up, make sure you see the new partition : fdisk -l |grep /dev/sdc
      
      
      
      
    • stop the application using app-util.sh -> option 2 (stop all)
    • create new LVM physical volume (PV) : pvcreate /dev/sdc2
      if this is the second disk extending the device will be /dev/sdc3
    • extend the LVM volume group (VG) : vgextend vg_data /dev/sdc2
    • extend the LVM logical volume (LV) :
      lvextend -l +100%FREE /dev/vg_data/lv_data
    • identify the /data file system type (for CentOS 7.2 based appliance the type is xfs) : cat /etc/fstab |grep /data
      
      
      
      
    • resize the file system according to the file system type :
    • ext4 : resize2fs /dev/vg_data/lv_data
    • xfs : xfs_growfs /dev/vg_data/lv_data
      
      
      
      
    • Display the new  size of mount point / data : df -h /data
