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 ?
I tried to find the type from blkid /dev/sda4 but that didn't give me the info so I tried
file -s /dev/dm-0
and it says XFS
So would I use xfs_growfs?

bingo! xfs_growfs can be used with the file system online, I'm pretty sure resize2fs requires the file system to be offline (unmounted).

Sorry, I missed that it would most likely be xfs. resize2fs doesn't necessarily require it to be offline, but it does frequently (though not always, IIRC), suggest running e2fsk first which should definitely be done while it's unmounted.

Online expansion of a filesystem is allowed by resize2fs. It is only for shrinking that being offline and running fsck is required.
xfs does not allow shrinking at all.
