Unless things have changed since last year, I advise not using glusterfs AFR on geographically disparate hardware. It does not handle latency well and failure to specify read-subvolume will cause it to randomly (apparently randomly, it isn't really random) try to read from a remote brick. As a test, set up your two most latent nodes in gluster replication, ...

I'd say lose everything. Do not virtualise this with VirtualBox, and do not use any cluster/replicating file system. Layers of complexity usually turns out to be layers of just that, complexity, bugs, slow-downs and instabilities. Keep it simple. Run Apache on the bare metal, and use NFS or rsync to move your data between your locations.

If you have the tooling in place you would be much better off just building your environment again. This way you can also be sure that none of the VMs have the same ...

A couple of things spring to mind here: When we converted, we used System Centre Virtual Machine Manager (hereafter referred to as SCVMM as life's too short) to take care of this. If you're serious about HyperV and you currently use vCenter to manage a VMware farm (rather than just having a couple of ESXi hosts that don't do much together) then I do ...

I'm not aware of any hypervisor that has functionality like this, and even if they did, you're talking about trying to capture the interactions of a protocol that's designed with security in mind. It sounds like you're using a *nix-based OS, which makes me think you'd get a lot of mileage out of OS-integrated monitoring and auditing tools (which have a long ...
