free disk space way off (too low)

[gleather]

cfdisk shows sda1 has size 30721.43MB, type Primary, fs type Linux ext3.
mount shows /dev/sda1 on /home type ext3 (rw)
df shows /dev/sda1 has 1k-blocks 640296 (way wrong).
1k-blocks should be around 30000000.

So, basically my 30 gig partition is showing as a 600 meg partition.

Any ideas?

What does df -h show? And I presume you're looking at the 'Size' column ;)

$df -h

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 626M 261M 346M 43% /home

If you used the optional [ blocks-count ] parameter when formatting
the partition with "mke2fs" and stated you wanted 626000 of 'em,
that's what you got. Or if you copied another 636 MB big file system,
perhaps a CD physically with "dd" or similar.

There are different ways to skin the cat.

I formatted the partition during an install of Ubuntu. I didn't notice that the size was wrong until it filled up.

My solution:

Boot into recovery mode.
cp -R /home/* /homebak
umount /home
mkfs.ext3 /dev/sda1
mount /dev/sda1 /home
mv /homebak/* /home

edit /etc/fstab with new GUID or just use /dev/sda1
chown -R /home/* appropriately

reboot

I still don't know why it happened.
