A tool that I am trying to install says:
MySQL server data directory needs to reside on an LVM volume
How do I check if my data directory is on LVM?

If you installed the OS then you would have chosen this option as part of the partitioning during installation. I assume you are looking to set up LVM snapshots (mylvmbackup) for MySQL?
If your seeing that message then i'm just guessing but you may not have an LVM volume, or at least MySQL data files aren't on it.

Try running lvdisplay on command line and is should display any LVM volumes if they exist.
