You can resize an ext3 filesystem with the resize2fs command. Both  
enlarge or shrink it.
But : this is allowed only on an *offline* (umounted) filsystem,  
resize2fs doesnt take care of the underlaying partition, you have to  
enlarge the partition (logical volume) before an enlarge operation or  
shrink it after a shrink operation.

man 8 resize2fs

<<
RESIZE2FS(8)

NAME
       resize2fs - ext2/ext3 file system resizer

[ ... ]
>>

Do the operation as following:
-unmount the logical volume holding the filesystem you want to enlarge
-lvwextend to enlarge the partition
-resize2fs to enlarge the filesystem
-remount the logical volume

Well, of course. ext3 is identical metadata-wise.
