Please use code tags for readability. You can edit your question, remove unnecessary empty lines and surround command output with [code]...[/code].

When you are not familiar with a command, use the manual. I would use the -L or -l option to specify the new size, and -r to also resize the filesystem. The lower case -l takes percentages as size, which can be handy.

Note that you can only extend a logical volume when there is unused space in its volume group.
