Hi, I'm trying to build a redundant duo of firewalls/routers/gateways and I'm thinking about not putting any disks in them and instead using a usb-stick raid-1 as storage. Has anyone any experience with this? Since the machines will be running pretty much only iptables, conntrackd and keepalived there is not going to be a lot of disk activity going on and the plan is to do all the logging on a remote machine which should reduce the write activity on the sticks to almost zero during normal operation.
I've already created a fairly minimal kickstart for such an installation but I'm wondering if there are any opinions out there on whether this is a feasible approach or if there are any gotchas I'm not aware of.
I/we have done this on a few systems with vanilla CentOS and no problems. Do note however that not all usb-sticks are the same (performance can vary _a lot_).
