Re: OCFS2 Setup
Please note that OCFS2 is not supported for production use on Linux for System z. This is largely due to a lack of extensive enough testing/QA work. It should work for you, but at this time its only recommended for testing. Now, if one needed to have a file system r/w from more than 1 linux server on z, what would the current supported recommendation be? And is anyone doing such with MQ Series? NFSv3 or AFS are reliable for this purpose and work well. GFS was supported for a while (before RH bought Sistina) -- might still be available. IBM will sell you GPFS. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

They say use ASM and RAC. That would be news to our product management teams and developers. Of course it wouldn't be the first time someone (or more than one) from Oracle has talked nonsense in public. Based on what I've heard from people involved in consulting engagements, RAC doesn't scale very well. At my previous job, the DBA ran into problems and Oracle's tech support told her to not use ASM. So, to me, OCFS2 looks to be a better choice.

OCFS2 Setup
Hello All, I'm trying to set up a two node ocfs2 cluster and run it on two SLES10 SP1 guests running in two different z/VM 5.3 lpars. The shared disk is an lvm volume comprised of 3390-3s, and I'm using the standard disk-based heartbeat and port . I was able to get this to work when both guests were running on the same system, but the nodes won't connect if they are running on two different z/VM systems. At first I thought it might be a network problem, but the nodes can ping and ssh each other. Is there something else that needs to be set up for this to work across lpars? Thanks. -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

A Firewall (internal or external) may allow ping and ssh, but not other ports.

There shouldn't be as far as OCFS2 itself is concerned, but as was suggested already, check for firewalls that might now be in between the two systems. A simple telnet other.system.name should show if that port is open or not.
