Hmmm. First please check if the files are really the, eg:
cmp ./25/fbackup/f.wine/fdrive_c/fTHE_FILM/fVIDEO_TS/fVTS_03_1.VOB
./24/fbackup/f.wine/fdrive_c/fTHE_FILM/fVIDEO_TS/fVTS_03_1.VOB
cmp ./23/fbackup/f.wine/fdrive_c/fTHE_FILM/fVIDEO_TS/fVTS_03_1.VOB
./28/fbackup/f.wine/fdrive_c/fTHE_FILM/fVIDEO_TS/fVTS_03_1.VOB
cmp ./25/fbackup/f.wine/fdrive_c/fTHE_FILM/fVIDEO_TS/fVTS_03_1.VOB
./26/fbackup/f.wine/fdrive_c/fTHE_FILM/fVIDEO_TS/fVTS_03_1.VOB
Second, was your hardlink check for the same host? You should double
check that this host is really on the same file system as the cpool
directory (eg: sometimes people try incorrectly to use symlinks for
TOPDIR/pc/HOST). You check with this:
df TOPDIR/pc/HOST
df TOPDIR/cpool
Finally, are there any errors in the XferLOG file?
