[OpenAFS-devel] RE: negative Quota

[Touretsky, Gregory]

There was a bug in server code, fixed by IBM in IBM AFS 3.6 patch 4
As far as I remember, volume used space became negative when one of =
it's
files exceeded (2GB-1k) or so

From patch 4 release notes:
Defect 12870 (APAR IY25146)=20
(All) This fix resolves a condition where various volume related =
commands
showed the used space of a volume as negative when the size of any file =
in
the volume exceeded 2 GB.=20

Salvaging volume will fix "used space" value

Subject: [OpenAFS-devel] negative Quota

Hello,
I created a new volume and set the Quota to 4000000 kbyte.
Then I try to create a 2 gbyte file:
>dd if=3D/dev/zero of=3D2gbyte bs=3D1048576 count=3D2048
Filesize limit exceeded
>ls -l
total 2097152
-rw-r--r--    1 hans     10100    2147483647 Oct 16 16:49 2gbyte
>fs listquota .
data.hans.test              4000000  -2097149  -52%         92%
>rm 2gbyte
>ls -l
total 0
>fs listquota .
Volume Name                   Quota      Used %Used   Partition
data.hans.test              4000000  -4194301 -105%         93% =20

I know that there is a filesize limit of 2^^31-1.
But now the used quota is wrong, and the quota limit does not
work as expected.

This is with Linux Kernel 2.4.19 and OpenAFS 1.2.7.
