statvfs() weirdness on alpha (RH-7.2 and CentOS-4.2)

[Bert de Bruijn <bob@xxxxxxxxxxxxxxx>]

Somehow I get very strange readings from statvfs() on Alpha.

On Intel
$ python
> > > import os
> > > print os.statvfs('/')
(4096, 4096, 1033182L, 234938L, 182454L, 525888L, 471255L, 471255L, 0, 255)

is correct. "df" with the same blocksize shows the same values
$ df -B 4096 /
Filesystem           4K-blocks      Used Available Use% Mounted on
/dev/hdd1              1033182    798244    182454  82% /

But on Alpha
$ python
> > > import os
> > > print os.statvfs('/')
(1024, 1024, 738193209530565, 551989197028090, 469096328178340, 0, 0, 255, 0, 0)

that can't be right, the whole / partition is only 500 MB:
$ df -B 1024 /
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda2               497861    325987    146170  70% /

469096328178340 is not an integer multiple of 146170.


BTW, this is not a python problem, perl Filesys::Statvfs has the 
same issues.


Can anybody shed a light on this ?

thanks,
Bert.
