I for one am not using it for anything but RAID volumes. I would never try to use a RAID controller for anything but RAID volumes (or even JBOD) anyway. You can't use non-disk devices with any of the other non-CAMified RAID controller drivers, can you? If you disable non-disk devices in mly, most people would assume that RAID controllers just don't/shouldn't do non-disk devices, at least in FreeBSD. If you think it would piss anybody off, make it a compile-time option wether or not the mly driver supports non-disk devices. Or even better, a sysctl tunable that can be set from the loader, just like hw.ata.* (hw.mly.cam_nondisk_filter?). My vote would be to _not_ support non-disk devices by default, but that might break POLA. :-) > Please, someone actually acknowledge that they're hearing me on > this?
