Hello, We have a cluster of 4 Xen servers. VMs are on a HP EVA 4000 SAN on a GFS2 FS. At the moment, the schedulers of VM and nodes are the default : NOOP for VM and CFQ for nodes. I read that when using SAN I should modify the scheduler on the nodes for NOOP because the SAN has a scheduler on its own. The article was a general one so some real life input would be great Regards, FM -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
