Re: [Linux-cluster] Corosync goes cpu to 95-99%




Thanks for that, that'll prevent me from modifying a system file...

And yes, I find it a little disapointing. We're now at 6.1, and our
setup is exactly what RHCS was designed for... A GFS over fiber, httpd
running content from that gfs...

Two thing I need to mention in this issue. One, support doesn't think anymore that it's a coro-sync specific issue, they are searching to a driver issue or other source for this problem.

Second, I downgraded my kernel to 2.6.32-71.29.1.el6 (pre-6.1, or 6.0), for another issue, and since I did, I don't think I saw that issue again. I saw spikes in my cpu graphs, but I'm not 100% sure that they are caused by this issue.

So, as a temporary work-around for this time, woule be (at your own risks) to downgrade to 2.6.32-71.29.1.el6 kernel :

yum install kernel-2.6.32-71.29.1.el6.x86_64
