This works great - running a pair off OSTs on some intel boxes with clients on the PPC64 nodes. Initial iozone measurements are making me happy, seeing fairly decent performance over gigabit ethernet through at least a couple switches (the servers are some older/slower machines that sit elsewhere in the machine room from the cluster). > and then tackle the big endian server separately (likely using > something > like 2.6.22 ext4 as the starting point for ldiskfs, since the > extent code > has proper endian swabbing already).

(config options, not applying some patches, etc?) I'd be happy to try things out but would need something of a roadmap to do so. thanks, --bob _______________________________________________ Lustre-discuss mailing list [email protected] https://mail.clusterfs.com/mailman/listinfo/lustre-discuss
