Strang df -h output

[Harry Putnam]

My setup:
*--
Software:
Linux kernel 2.6.7-1.517 Architecture i686
Fedora Core release 2.90 (FC3 Test 1)
Hardware:
model name	: Intel(R) Pentium(R) 4 CPU 2.00GHz
cpu MHz		: 1994.800
*--

I'm seeing output from `df -h' that I've never seen before.  Not sure
when it started but I think it could only be a matter of days at most
since I last ran `df -h' for some reason.

Filesystem            Size  Used Avail Use% Mounted on
[...]
/dev/hda5              36G   20G   15G  58% /anex
none                  253M     0  253M   0% /dev/shm
/dev/hdb9             7.6G  448M  6.7G   7% /home
/dev/hda2              15G  -64Z   15G 101% /mnt/pack
/dev/hdb11             12G  4.6G  6.0G  44% /news
[...] some unnecessary stuff snipped

Note the strange output for /dev/hda2 (/mnt/pack)
What on earth does that mean?

That partition actually has 2.6 gigs of data on it by `du' reconning:

du -sh /mnt/pack
2.6G    /mnt/pack

Its not a symlink or something:

  ls -ld /mnt/pack
drwxr-xr-x  10 reader reader 4096 Sep  4 10:54 /mnt/pack

So what is that output telling me?

Yeah. something is really wrong with reporting disk usages since  last
few days rawhide updates.

First seen after the famous gawk broke my initrd 

justine [8:34] root /etc#df -h

Filesystem            Size  Used Avail Use% Mounted on
/dev/hda3              41G  2.9G   36G   8% /
none                  632M     0  632M   0% /dev/shm
/dev/hda1              14G  8.4G  4.2G  67% /vmware

btw same w/o -h 

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda3             42829268   2947356  37706312   8% /
none                    646716         0    646716   0% /dev/shm
/dev/hda1             13844044   8770988   4369816  67% /vmware


Hmm last time i had ~10G free on / but now my partition has 36G free ???

My home dir on that partition  contains 16796m of data 

justine [8:42] root /home/xl#du -ms .
16796   .

Looks like a curvature of space on my disks ;)  nice.

hehe... have you seen anything like the `-64Z' I posted.
Wonder what Z stands for anyway?

They are powers of ten:

1. Kilo 
2. Mega 
3. Giga 
4. Tera 
5. Peta 
6. Exa 
7. Zetta 
8. Yotta

A drive with 64Z would be worth hanging on to. :)

But the showstopper reported was -64Z.... hehe

I was getting a -16Z but I didn't noticed until earlier today.

FWIW I've also seen wierd numbers for /boot partition (du -sk was fine
- but df showed 101% full or something like that). I noticed this
after the boot issues with module-tools (and reverting back to 533)

I've repartitioned this disk since then - and did a fresh install off
boo.iso/rawhide - which is working fine with kernel-541

My first indication was on Sep 1 when I received this:

/dev/hda1 (/boot) is 101% full -- -16Z of 99M used, 104M remain

This was immediately after having updated FC3T1 with with a large 
batch of new packages including the dev-3.9.2-1.i386.rpm and 
kernel-2.6.8-1.538.i686.rpm packages, both of which proved unusable 
on my machine (and may be simply a co-incidence).  Since my 
configuration is a dual boot between FC3T1 and FC1, which share a 
common boot partition, the fact that I receive the above message in 
FC1 tells me it's not a problem with the "df" utility but rather 
something that's gotten hosed in the disk's partition information 
because of something that happened during or after the FC3T1 
update.

Oops, the troublesome dev-* package for me was dev-3.11-1.i386.rpm 
(Sep 3rd) not the one listed above.

Here's a list of the files that were installed on Sep 1.

Looks like someone filed a related bug yesterday ...

Exactly the same case:

Filesystem            Size  Used Avail Use% Mounted on
/dev/hda6             9.7G  8.1G  1.1G  89% /
/dev/hda2             190M  -16Z  306M 101% /boot

I repartitioned the /boot partition to fix it.

I didn't have any problem with module-init-tools-3.1-0.pre5.1, because I
noticed the problem before rebooting I reinstalled the previous version.

In may case this happened after installing kernel 541. Don't know if its
related but  package "dev-3.11-1" fails to install in here.
