I'd like to measure the total amount of data written over time to the physical devices that make up zpool zils, l2arcs, and vdevs. Each one of these physical devices has a projected Mean Time Before Failure (MTBF), often measured in writes or data written to the device, which I'd like to compare with the total number of writes to the device.
The "zpool iostat" command can do this for a given period of time, but unless I'm mistaken, it can't do this continually for an unpredictable amount of time. I'm imagining that something like this can be done using dtrace, but I'm not completley certain if that is the best way to tackle the problem. Are there any other ways to do this?
