Just so somone else might learn from my stupidity 😀 The disk space issue caused by the huge log file wiped out my mt-daapd.conf file so Firefly would not start at all. I simply restored the file by copying over the mt-daapd-example.conf file and edited it accordingly to bring the server back to life. Doing this on an HP MSS is a little hard unless you remote desktop connection in to the box…you can then see all of the config options easily from the system tray icon, and you can edit the config files and read the log files in Windows Notepad. Much easier than using the command prompt from the toolkit that MS provides in WHS.
