The algoritm is very old and if your IP numbers do not reflect your
network topology it probably yields incorrect results.
Have a look at man fs_setserverprefs and man fs_getserverprefs
a lower value indicates a greater preference
but first check that the clients really knows that there is more than one copy
(something like this):
$ fs where /afs/pdc.kth.se/home/
File /afs/pdc.kth.se/home/ is on hosts kinilaw.pdc.kth.se morena.pdc.kth.se
sculpin.pdc.kth.se houting.pdc.kth.se
As my list from fs gets is quite long, I came up with this to find out
which one should be the prefered server:
$ fs gets | awk '$1 ~ "'$(echo $(fs where /afs/pdc.kth.se/home/ | awk -Fhosts\
'{print $2}') | sed "s/\ /|/g")'"' | sort +1 -2n
