Setfattr always returns operation not supported

I'm trying to get a script working however I'm having issues with a particular line trying to set file attributes with setfattr. The line in question is ret=os.system('setfattr -n "user.dummy" -v "dummy" /apachelogs/data/file') The fstab output of this location is as follows. /dev/sdb1 /apachelogs reiserfs user,noauto,rw,exec,suid,user_xattr 0 2 Returns the error message: setfattr: /apachelogs/data/file: Operation not supported Can anyone give me any advice on what I might be doing wrong? My google-fu is only telling me that the problem usually occurs when someone doesn't prefix user on the first variable. Cheers.
