sudo resize2fs /dev/lvname/root

I get:

resize2fs: Bad magic number in super-block while trying to open /dev/lvname/root Couldn't find valid filesystem superblock.

what file system type is this /dev/lvname/root ?

oops, left out the rest...

since you said C7, its quite likely its XFS not extXfs ... if thats the case, then use:

xfs_growfs /dev/lvname/root

if you use pass the '-r' option to lvextend it will resize the volume for you based on the filesystem that is on the volume. no need to grow it manually afterward.
