Shane,
Regarding the read performance issues you mentioned today, could you
take a look at this bug, resolved in Lustre 1.4.7, to see if it
resembles the problem you're seeing:
https://bugzilla.clusterfs.com/show_bug.cgi?id=10265
I've heard a few reports today at SC about slow read performance use
cases in 1.4.6 and 1.4.7, which I'd like to get on top of
immediately. If this is not a match for your case, please file a
Bugzilla ticket and let me know the number. I'd like to hand this off
promptly to a senior IO specialist.
Thanks,
Peter
