I have a Dell MD-3000 hooked up (via SAS) to 2 (will be 4 in actual usage) Dell 2900 series servers. I would like to know the _bare_minimum_ set of stuff I need to configure to share a filesystem between the two devices, keeping in mind the following criteria: * The devices will mount the filesystem ro - there will be only a single node mounting the filesystesm rw * The root filesystem or other system files will not be mounting the array - just a filesystem with shared data. * The applications that will be accessing the data will be Apache (read-only), as well as (on the rw host) rsync or some other standard utility to keep things up to date. So given that, is fencing each host and having a full cluster setup really necessary? Given that gfs (and the application(s) accessing the image do POSIX compliant file locking, isn't there some simpler way to accomplish this? Assuming it is necessary, I should be able to use IPMI on the individual hosts to fence the devices, correct? Obviously NFS would be a bit simpler, but even with a NetApp or other filer appliance, and the latest versions of NFS, I'm a bit concerned that the performance wouldn't be as good. w -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
