I am running a home-brew NAS Cluster for a medium sized ISP. It is run with a pair of Dell PowerEdge 2900 with 1 Terabyte of filesystem exported via NFS to 4 nodes running apache, exim and imap/pop3 services. Filesystem is made on top of drbd in a active/backup setup with heartbeat. Performance are good, but can be better with more memory on nfs node and faster disks. I don't know VMware very well, but I run other virtualization solutions, like QEMU. Do you plan to mount the NFS from inside the virtual machine or create a virtual disk on an exported NFS filesystem?

My budget won't stretch to a commercial NAS solution, so it's either a SAN, which could get complicated and hard to manage with so many nodes, or a home-brew NAS solution. Has anyone done this, on the list? I'm wondering what the catch is? I'm thinking all I need to do is run NFS on top of a clustered filesystem, and export to ESX. I could use some pointers, gotchas, ideas and experiences. Thanks! S. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
