Hi,
We have the cluster set up by two identical 4100 with memory channel
installed. Both are running DU4.0b, TCR141 and with the latest patches
applied. Our problem is that the time required to relocate the NFS service
is unacceptable. With the service mounted by client, the relocation time,
say from member A to member B, is just few seconds. However from B to A,
the required time is ranging from 1 to 4 minutes.
I then used ping and arp to verify the correct MAC address the service
belongs. In my first case, i.e. from A to B, the MAC address of that nfs
services changed immediately. And for the later one, it stayed with the
original MAC address until, what I think is arp cache timeout, or until I
cleared that entry by "arp -d nfs_service". On Alphastation, this takes
about 1-2 minutes, and on Sun with Solaris, it takes 2-4 minutes.
Any ideas are welcome. TIA.
Regards,
Raymond
P.S. The daemon.log shows that the service is relocated successfully within
just few seconds in both cases.
