Jim,
Just a clarification. the kernel version in which I am seeing deadlock problems is 3.5.10, much later than the version in which you are interested. You should be fine with kernel versions up to, but not including, 3.4.

Jim, I am not sure about the 3.0.60 kernel. There are some deadlock problems with the OrangeFS kernel module with later versions of the kernel. This is on my list of things to do, but it has taken a back burner for a little while. As far as upgrading from OrangeFS 2.8.5 to 2.8.7, there are no conversions required and the upgrade should be straightforward with only a short outage required for restarting the server processes.

Hi all: I'm running Rocks 6.0, which is based on CentOS 6. There's an issue with the kernel supplied in CentOS that hinders performance in many areas (including network throughput). One of the suggestions is upgrading to a 3.0.60 kernel. Will OrangeFS 2.8.7 build well against the 3.x kernel series? Any known issues I should be aware of? Also, my OrangeFS servers are currently running 2.8.5, and I plan to upgrade them to 2.8.7 as well. Are there any issues or conversions required? I would rather not plan on a quick change over and restart pvfs2 only to find its going to be converting/processing for a few hours before coming online. If its going to take some time, I need to schedule a chunk of downtime... Thanks! --Jim
