Hey Sven,
This is regarding mmap issues and GPFS.
We had discussed previously of experimenting with GPFS 5.
I now have upgraded all of compute nodes and NSD nodes to GPFS 5.0.0.2
I am yet to experiment with mmap performance, but before that - I am seeing
weird hangs with GPFS 5 and I think it
Thanks a lot Sven.
I was trying out all the scenarios that Ray mentioned, with respect to lroc and
all flash GPFS cluster and nothing seemed to be effective.
As of now, we are deploying a new test cluster on GPFS 5.0 and it would be good
to know the respective features that could be enabled and

GPFS 4.2.3.2 and CentOS7.
Here is what i observed:
