Yes, you would need minimum of two NICs per node (say eth0 and eth1). Devote one NIC for ctdb/nodes(e.g. eth0) and configure this IP address to be internal IP address used by your file-system (GFS/Lustre/GPFS). Use the other NIC for ctdb/public_address (e.g. eth1 or bond0) which is totally managed by CTDB (IP failover + failback as node fails/recovers). The public address should be used for NFS/SMB export.
You need to manually start ctdb on all the nodes. I use parallel shell (pdsh) to start CTDB in parallel across nodes (use eth0) to launch. Pdsh internally uses rsh or ssh across nodes. http://linux.die.net/man/1/pdsh syntax pdsh -a "/etc/init.d/ctdb start" HTH, -Kums On Sat, Feb 14, 2009 at 6:06 AM, Ken Lupo <[email protected]> wrote: > I am trying to understand the ip addressing with nodes and public > addresses.
