Well, I thought I did (except for stbuf->f_fsid = 10815, that is :-)

Ok, running strace on getconf I see (for my FUSE FS):

statfs("/mnt/dcfs/.", 0xbf819960)       = -1 EOVERFLOW (Value too large for defined data type)

(contrast this with 
statfs("/scratch/utcke/SUFS/", {f_type="EXT2_SUPER_MAGIC", f_bsize=4096, f_blocks=52192014, f_bfree=9202139, f_bavail=6508140, f_files=53903360, f_ffree=53827351, f_fsid={0, 0}, f_namelen=255, f_frsize=4096}) = 0
for another non-fuse FS)

So what's going on there?  I'm using

#define FUSE_USE_VERSION  25
int dcfs_statfs(const char *path,
                struct statvfs *stbuf)

since /usr/include/fuse/fuse.h said:

     * Replaced 'struct statfs' parameter with 'struct statvfs' in
     * version 2.5
     */
    int (*statfs) (const char *, struct statvfs *);

Wierd.  BTW, this is Fuse 2.6.3, which comes with my particular
version of REL... then again, changing struct statvfs to struct statfs
doesn't help either (but does give the wrong results in df, so I guess
statvfs is fine, as I then get:

hasgksssven>/.../utcke/src/SUFS% df -h /mnt/dcfs
Filesystem            Size  Used Avail Use% Mounted on
dcfs-main             7.2T  7.2T   25G 100% /mnt/dcfs

Clueless
