358 actually works okay for us, so YMMV.  431 we found to be unusable under heavy load--any kind of backup-like activity would cause large load fluctuations, high glock_workqueue activity, and frequent fencings.  The one cluster where we rely heavily on GFS2 lasted 5 days (with ~8 fencings) on 431 before we backed off to 358.  Dunno when we'll have the time to investigate further, we do need a better simulation of our production loads on our test cluster.
