Steve,
Thanks for the informative, and detailed response -- it really helps
to understand what might be happening. We're not mounting with noatime,
and it sounds like that would be a good first step.
Thanks!

Steve,
Thanks for the prompt reply. Like Kaerka, I'm running on
large-memory servers and decreasing demote_secs from 300 to 20 resulted
in significant performance improvements because locks get freed much
more quickly (I assume), resulting in much better response. It could
certainly be th
If in gfs2 glocks are purged based upon memory constraints, what happens if
it is run on a box with large amounts of memory? i.e. RHEL5.x with 128gb
ram? We ended up having to move away from GFS2 due to serious performance
issues with this exact setup, and our performance issues were largely

Hi all,
On RHEL 5.3/5.4(?) we had changed the value of demote_secs to
significantly improve the performance of our gfs2 filesystem for certain
tasks (notably rm -r on large directories). I recently noticed that
that tuning value is no longer available (part of a recent update, or
part of 5
