All,
We are pleased to announce the release of OCFS2 1.2.7-1 for RHEL4
and RHEL5 on i686, x86_64, ppc64 and ia64 architectures.
This release includes three frequently requested updates:
* Fix for bug#5852483. This concerns a possible memory leak in the
size-64 slab during asynchronous io. This
qs is why is the io not completing within 60 secs? You could
try increasing the hb threshold to say 46 (90 secs).
It could be that that while that system may not be doing any
heavy io but some other system using the same storage is.
Has that been ruled out?
In the end, we have to first
Is it a second, as in, just a sec? :)
This could be the result of using the default cluster timeouts
which were fairly low. Refer the Cluster timeout section in the
FAQ for details. You should be able to bump up the disk heartbeat
threshold as recommended. For network timeouts, you will need
