They use mfi, like a few others which do not have CAM loaded. The best part is, after rebooting these firewalls on their new 8.2-RELEASE-p5 kernel, they haven't loaded neither of UMS, UMASS, or CAM, although I've clearly built them: MODULES_OVERRIDE=cam geom/geom_label if_lagg linprocfs linsysfs linux mfi/mfi_linux usb/umass usb/ums I doubt another admin would have loaded them manually, they don't touch the "freebsd stuff" very often ;) Ah well, I guess I'll just leave it at that. For anyone reading this thread, Matt's suggestion of using lsof to find what files/binaries could be using the devices seems to be the best one. Ty for the input Matt. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
