Hi, I run smartmontools on my storage servers, to launch periodic disk tests and alert on disk errors. Unfortunately, if we set sysctl kern.securelevel >=2, smartmontools does not work anymore. Certainly because it needs to write directly to raw devices. (details of the levels, -1 to 3, in security(7)) Any workaround to this ? Perhaps we could think about allowing SMART commands to be written to disks when sysctl kern.securelevel >=2 ? (I assume smartmontools writes SMART commands) Thank you very much ! Ben
