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

Hi Steven and Nicolas,

  Is this bug resolved in RHEL6.1 with all updates applied?? Do I need to
use some specific kernel version 2.6.32-131.2.1 or 2.6.32-131.6.1?

Thanks.


the corosync portion is going through QE.  The kernel portion remains open.

Regards

Thanks Steve, then, Can I use last corosync version provided with RHEL6.1 and last RHEL6.0's kernel version without problems??
