This isn't a LVM question, it's a filesystem question.... Specifically:
$ man mke2fs
...
-m reserved-blocks-percentage
Specify the percentage of the filesystem blocks reserved for the super-user.
This value defaults to 5%.
...
So 5% of 59GB is ~3GB. 59-3 = 56GB available.
As you can tell, 5% is huge. For non-root/OS filesystems, I almost
always set that to 0. Look at tune2fs to see how to do that without
recreating the FS.
