We see dramatic performace, df's may take 10+ minutes, and above approx. 100 Mbit/sec total network traffic (mostly read from GFS disks) the performance goes up and down, sometiems back to 5 Mbit/sec etc. I have statfs_slots now set to 128, or should that be bigger? We created now one fs with larger RG's and at least df works better, but I fear we also have to do the other patches. -- -- 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
