Check the output of the 'df' command.  It will tell you the device the
filesystem is on, the size (in 1 KiB blocks), how much is used, how much
is available (again in 1 KiB blocks), the percentage used, and the
mountpoint.

Your listing for 1 KiB blocks should match up pretty closely to what the
filesystem's containing partition's size is.  It may not be exact.  But
if you grew the partition by, say, 1 GB, and you're coming up 1 GB
short, then the fix is pretty simple:

  sudo resize2fs /dev/device

Will resize the ext4 filesystem online.  It shouldn't take that long to
do; longest I have seen it take is roughly 15 minutes for a growth of
several tens of gigs.
