[wellylug] Blocks count discrepancy fdisk & df

[Blake Watkins]

Hi Carl,
Not sure if you've fixed this or not, but it looks as though you've
increased the partition size, but haven't resized the file system that's on
the partition. Have a look at the resize2fs command. I think what you need
is:

resize2fs -p /dev/hda3 (assuming it's an ext2/ext3 filesystem)

Which should extend the filesystem to use all the space on the partition. It
should leave all the data that's on the file system there, but make sure you
back everything up just in case things don't work.

Cheers,
Blake
