After over a week of trying to figure out what to do about a cluster system, and over 5 days of trying to compile, install, configure redhat's GFS, i got frustrated and gave up and took another look at ocfs2 today. I have to say, you guys put this together pretty slick. I do still want to try out GFS but after 5 days of mucking around with downloading different versions of 4 or 5 different software pieces (device-mapper, openais, cluster, lvm2, udev) and not getting ANYWHERE i gave up. so today I installed a new linux-2.6.19.2 kernel with ocsfs2 modules, installed iscsi-target on a test server using a 500g sata drive and then installed the ocsfs2-tools-1.2.2 rpm on two FC6 machines and got it all working in one work day today. I had to do a little messing around with the configs and iscsi stuff, and figuring out to increase the heartbeat timeout to prevent self fencing and stuff, but once that was done it was pretty cool. So heres a good job on keeping things pretty damn simple! Install a kernel and one rpm and make a configuration file and thats about all it took. Very nice! Im looking forward to doing a bunch of testing tomorrow after i do an entire clean os install on all the machines and see if i run into any problems.
IF you need to DOWNLOAD and COMPILE KERNEL component THEN this system is not production ready. ENDIF (Reason - your personal combination of module, kernel, libraries and other components was never tested in the wild). Don't forget, when testing OCFSv2 on iSCSI, that it require 3 (not 2) servers for the stable cluster configuration, and that, if you use iSCSI, you may want to increase heartbeat timeout few times (default is 12 seconds, and Ethernet convergence time is 40 - 50 seconds).> After over a week of trying to figure out what to do about a cluster > system, and over 5 days of trying to compile, install, configure > redhat's GFS, i got frustrated and gave up and took another look at > ocfs2 today. > > I have to say, you guys put this together pretty slick.

We're looking to change some defaults in a future release (as a first step - there's more to be done there). In the meantime, 2.6.20 will have the ability to let the user configure network timeouts, so that might help folks hitting those.> So heres a good job on keeping things pretty damn simple!

We really do appreciate them :) Simple configuration was one of our design goals, so it's good to hear that it's working out.> Im looking forward to doing a bunch of testing tomorrow after i do an > entire clean os install on all the machines and see if i run into any > problems.Cool. If you hit any problems, feel free to mail this list (and file a bugzilla please). --Mark -- Mark Fasheh Senior Software Developer, Oracle mark.fasheh@oracle.com
Mark, I think that SLES includes your kernel module in its distributions & regular updates these days. When will Red Hat be doing this for RHEL?

To clarify - the 1.2.x series (for which we make rpms available) is a bugfix only release. Anything that's fixed in mainline is backported to that svn branch. Most of the time fixes get uploaded simultaneously. If you don't believe me, subscribe to the ocfs2-commits list (which tracks 1.2.x commits). So, please try to relax, and cut down on the constant yelling. It doesn't help anyone... --Mark -- Mark Fasheh Senior Software Developer, Oracle mark.fasheh@oracle.com _______________________________________________ Ocfs2-users mailing list Ocfs2-users@oss.oracle.com http://oss.oracle.com/mailman/listinfo/ocfs2-users
