From the Console

Enter the following commands as root.
  1. (Optional) View the amount of free disk space available. 
    [root@localhost cpn_service]# df -h
  2. Signal to the OS that there has been a hardware change to the disk. 
    [root@localhost cpn_service]# echo ‘1’ > /sys/class/scsi_disk/2\:0\:1\:0/device/ rescan
  3. Expand the physical volume. 
    [root@localhost cpn_service]# pvresize /dev/sdb -v
  4. Extend the size of the logical volume for MySQL operations.
    This example shows that we are extending the size of the logical volume by adding 25GB. 
    [root@localhost cpn_service]# lvextend -L +25G /dev/mapper/application_vg-mysql
  5. Resize the file system. 
    [root@localhost cpn_service]# resize2fs /dev/mapper/application_vg-mysql
    This writes your changes to disk and completes the partition expansion process.
  6. Verify the amount of free disk space available. 
    [root@localhost cpn_service]# df -h
    The output should indicate the increased partition size.
