To avoid an error in calculating the correct number of logical extents,
and possibly doing an lvreduce(8) to a size smaller than the filesystem:

Use resize_ext2(8) without a size argument.  This will resize the ext2
or ext3 filesystem to be the same size as the logical volume containing
it.  After doing this, e2fsadm(8) can be used to resize the filesystem
and logical volume "simultaneously" to any desired size (that can
contain the filesystem's data).
