Hello, I have a small four SATA bay machine (HP ex470) which I'm using as a NAS with FreeBSD+ZFS. It has four dual color leds for each SATA bay (red and blue + purple if lit together) Which I'm controlling either from userspace by writing data to the enclosure management ioport, or recently I've made a kernel module which uses the led(4) framework and exports the leds as device nodes in /dev. What I'm wondering now is, if there is an easy way to access geom/disk stats from in kernel and make the leds flash only during disk activity, without having to do it in userspace? -- Regards, Nikolay Denevhelp
