Are you using journaling or is the filesystem ext2 or ext3? Because if you are resizing ext3 according to this fellow http://www.hermann-uwe.de/blog/resiz...ns-with-parted
you have to disable and re enable journaling. This is what I think you have to do now, that you have already resized the partition.
First you'd better unmount your home partition.
So try removing the journal from your home partition, lets say it is /dev/sda4, turning it to ext2 by:
tune2fs -O ^has_journal /dev/sda4
Then check the size of the partition or maybe run fsck just to be sure everything is fine, I suppose by now it should indicate correct size. Then turn journaling back on with:
tune2fs -j /dev/sda4
