I maintain a lot of servers, each of which have numerous external drives/arrays attached. Occasionally one of these arrays will go off line (I’ve been having a lot of problems with aging OWC “Qx2” units which simply go off line instead of going into alarm). So I wrote a script (actually an app) that I run every hour using Launchctl, which checks a list of drives that should be mounted, and emails me if any are not mounted. Works fine, but here’s my question: if a drive is off line, I will continue to get an email every hour until I unload the daemon. Or, I could create a file and write to it, then check it as a flag so that it won’t email me if the flag is set. But then I have to manually clear the flag, which seems like just as much trouble as unloading the daemon. I could also possibly unload the daemon from the script itself, not sure if that’s possible. Can anyone think of a better way to handle this?
