Renaming a logical volume is a three step process:
Rename the LV
Remount the file system
Update /etc/fstab
Begin by listing all the logical volumes on the system
Let's find out where DataLV is mounted
Rename DataLV to TCPDumpLV
Verify the logical volume has been renamed
Notice the user space has yet to be updated, this is because the file system must be remounted
Remount the file system to update the user space
Verify the file system has been mounted
Update /etc/fstab to reflect the new name of the file system
Nice work, you now know how to rename a logical volume!
