Once my frontend is booted, I don't think it hits the disk at all, so
I'm not too worried about that. The only time the disk gets hit is
when I recompile, which is not that often, and I'm not usually
watching anything when I do that anyway. It is also a slave backend,
but it doesn't record all that much, and when it does, it uses NAS
disk, and the DB is on another server, so again local disk usage is
minimal.
