Hi,

I plan to run my two (1.6.0) openafs servers (both are vl pt vol and
dafs servers) in a failover configuration (the failover supervised by a
redhat-cluster installation). The data is on a SAN which is attached to
both servers.
I plan to define a service for both nodes with its own ip address and
partitions. On normal operation node1 is going to have ip address
192.168.0.1 and all the partitions from vicepa to vicep... and node2 is
going to have ip address 192.168.0.2. If any of the nodes would fail the
service would get transfered to the other node, thus receiving its
partitions and ip address. With Netrestrict files will restrict the ip
addresses the pt vl and fileserver components can bind to those defined
at the clustering (192.168.0.1 and 192.168.0.2). The startup of any of
the services (on any of the nodes) would mean a complete restart of all
of the services controlled by bos. I also plan to put |fsstate.dat of
the service running normally on node1 on shared storage.

Please tell me if I've overlooked anything. Won't get the the vl and pt
server confused from running on both addresses declared in CellServDB in
case of failover?

Thank you in advance!

Geza
