Narrow down your candidate list of distributed filesystems and read the documentation for each of them. I'd guess that each one of them has a recommendation of some sort for the local storage node filesystem and the reasoning behind the recommendation. Given the manner in which most of them derive their parallel performance, the local filesystem is likely not critical. You mentioned an IP SAN. Have you looked at GFS2 and OCFS? You haven't mentioned a workload. We could better serve you if you described the workload. -- Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
