(Yep, it's me again) We've worked around some minor glitches and now have a pair of nodes happily sharing an OCFS volume. I was wondering, though, if it was possible to configure a second private IP address so that the nodes could communicate over more than one Gigabit Ethernet connection. Our RAC books and online docs make some vague references to multiple interconnects, but I have yet to see an actual explanation of how that works. I suppose I could try using the Linux bonding driver to pair up the NICs, but I'd prefer if this was something that Oracle could handle. Thanks, by the way, for all the help so far. Everything's running nice and smoothly now. Derek
I forgot if I responded ocsf doesn't support multiple networkcards, however, it has fallback to disk if sometihng would happen to the network, and, for oracle io, there is no locking so it would only affect file extending, new file create etc. for the oracle stuff, 10g can handle it, not 9i On Wed, Feb 11, 2004 at 03:26:43PM -0800, Derek Suzuki wrote:> (Yep, it's me again) > We've worked around some minor glitches and now have a pair of nodes > happily sharing an OCFS volume.

Thanks for the info. Do you know if anyone has tried using the Linux bonding driver to channel-bond a pair of NICs for redundancy?> -----Original Message----- > From: Wim Coekaerts [mailto:wim.coekaerts@oracle.com] > Sent: Friday, February 13, 2004 12:00 PM > To: Derek Suzuki > Cc: 'ocfs-users@oss.oracle.com' > Subject: Re: [Ocfs-users] Multiple interconnects > > > I forgot if I responded > > ocsf doesn't support multiple networkcards, however, it has > fallback to > disk if sometihng would happen to the network, and, for > oracle io, there > is no locking so it would only affect file extending, new file create > etc. > > for the oracle stuff, 10g can handle it, not 9i > > On Wed, Feb 11, 2004 at 03:26:43PM -0800, Derek Suzuki wrote: > > (Yep, it's me again) > > We've worked around some minor glitches and now have a > pair of nodes > > happily sharing an OCFS volume.

Yup. Just make sure that you know how your switch is configured for bonding to behave the way you want it to - ie., layer 3 switch for load balancing (mode 1 , 2,3 for load balancing in bonding) or layer 2 (mode 1 for failover in bonding). Also, I have found that 6.2.11a bonding driver is more stable than the latest 7.x version. -----Original Message----- From: Derek Suzuki [mailto:DSuzuki@ZipRealty.com] Sent: February 13, 2004 3:56 PM To: 'Wim Coekaerts' Cc: 'ocfs-users@oss.oracle.com' Subject: RE: [Ocfs-users] Multiple interconnects Thanks for the info.

Neat. Can this made to work with direct crossover-connections for a two-node cluster, or will I need to have a pair of trunked switches to get real redundancy?> -----Original Message----- > From: Rui Amaral [mailto:ramaral@rim.net] > Sent: Friday, February 13, 2004 1:01 PM > To: Derek Suzuki; Wim Coekaerts > Cc: ocfs-users@oss.oracle.com > Subject: RE: [Ocfs-users] Multiple interconnects > > > Yup. > > Just make sure that you know how your switch is configured > for bonding to behave the way you want it to - ie., layer 3 > switch for load balancing (mode 1 , 2,3 for load balancing in > bonding) or layer 2 (mode 1 for failover in bonding).
