[Ocfs2-users] OCFS2 volumes do no mount automatically on RHEL4 also

On RHEL4 also, the service o2cb starts later than _netdev device mounts.
So mount fails. Should the o2cb service start earlier to fix this?

SLES does not appear to have the script to support mounting
_netdev devices on boot.

So, add the command(s) in /etc/init.d/boot.local to explicitly
mount the volume(s) on bootup.

mount -t ocfs2 /dev/sdX /dir

To avoid a single point of failure, we are configuring an Oracle cluster
with two private NICs per node. They are directly attached via crossover
cable to its peer on the other server (two-node cluster).

How can we tell OCFS2 that it has available a second card?

Here is our cluster.conf:

node:
        ip_port = 7777
        ip_address = 10.10.2.1
        number = 0
        name = neo
        cluster = rac

node:
        ip_port = 7777
        ip_address = 10.10.2.2
        number = 1
        name = trinity
        cluster = rac

cluster:
        node_count = 2
        name = rac

Thanks,
Ivan

OCFS2 doesn't specifically deal with this setup itself.  You can 
configure the two interfaces to be bonded into a single logical one in 
the kernel and OCFS2 will use that bonded interface, via its IP address,

just like it would a typical single interface.

A good place to start might be the kernel's documentation of this 
functionality.  It mentions that some distributions have config files 
that help manage the bonded interfaces.
