In the meantime we rebuilded all fs's with larger RGs (-r 2048), which already improved the "df" behavior seriously. Also, fs performance is not that bad w.r.t. bandwidth (our measurements were first incorrect due to 32-bit counter troubles), but operations like rsync (which we do a lot) that scan large directory trees are horrable. For that we'll wait for 5.1. -- -- Jos Vos <jos@xxxxxx> -- X/OS Experts in Open Systems BV | Phone: +31 20 6938364 -- Amsterdam, The Netherlands | Fax: +31 20 6948204 -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
