hi guys,
can anyone tell what is wrong with "Lost contact with file server " issue?
that afs clinet is not in the same domain of afs server. the connection
speed is up to 16MB/sec.
my afs server is Scientific Linux SL release 5.0 x86_64 2.6.18-53.1.6.el5 #1
SMP. i use openafs-server-1.4.6-58.SL5.x86_64 rpm.
client kernel is 2.6.18-53.1.13.el5. that is SL5 x86, too. i use
openafs-client-1.4.6-58.SL5.x86_64 rpm in clinet.
following are clinet /var/log/message logs:
