df works for me with smbfs/cifs ... you didnt say what the filesizes are *supposed* to report ... also, what version of coreutils do you have exactly ?

Clearly this is a bug in your file system or kernel or something like that, but 'df' should output more-useful information even when there's a bug elsewhere. I think the output should look like this: Filesystem 1M-blocks Used Available Use% Mounted on //ehngsa.ibm.com/ 2192704 -480512 2673216 - /mnt/GSA I've installed the following patch to CVS coreutils, so that it generates this output. 2006-01-24 Paul Eggert <eggert@cs.ucla.edu> * src/df.c (show_dev): If the file system claims to have more available than total blocks, report the number of used blocks as being total - available (a negative number) rather than as garbage.

then i'm gonna consider this fixed as the issue will be in the next release of coreutils thanks for doing the hard work and making me look like a slacker :)
