Spooky bad values from df

df is returning really bad values. Here, I'll show you:

Code:

[tachycardic:caidence]$ df

Filesystem          1k-blocks      Used Available Use% Mounted on

/dev/hda1            -2647926523368        1        0  9% /

/dev/hda2            -515486986193        1        0  1% /home

/dev/hdc1            -15106703008423        1        0  31% /var/ftp

[tachycardic:root]# df -m

/dev/hdc1            -14752639657        1        0  31% /var/ftp

[tachycardic:root]# df.giga

Filesystem          1G-blocks      Used Available Use% Mounted on

/dev/hda1            -2525260        1        0  9% /

/dev/hda2              -491607        1        0  1% /home

/dev/hdc1            -14406875        1        0  31% /var/ftp

I am running a very simple, new, linux box (Debian 3.0 Woody).
hda1 and hda2 are simply enough ext2,
and hdc1 is a brand spanking new ext3, but it just took a lot of activity.

Also, mind you, according to the system, hdc1 is full, not at 31%

Could this be ext3's doing? Any clue?

Thanks,
Caidence

That's very strange. I'm thinking that maybe df is screwed up somehow, but I wouldn't bet my data on that.

You might want to drop to emergency mode (a variety of single-user mode where the partitions are mounted read-only - boot with params "linux emergency" in LILO or GRUB), then run fsck on each partition to fix any corruption.

Other than that, if you have a bootable Linux CD (the Woody install CD should be good enough for this, try booting that, getting to a shell, mounting your partitions, and see if df works correctly on that setup. :twocents:

Just in case df is screwed, you might try reinstalling df (and the other core utilities) with apt-get install --reinstall coreutils.

Other than that, you have me stumped.

This can also happen if you chose a different inodes / blocks layout for your partitions.

Did you choose something other than default?
