    How does LMS cope with sudden powercut / harddrive disconnection ?

    This has happened a few times to me, sometimes screwing up things (e.g. album art).

    How does LMS deal with this when on the middle of a search ? Revert back to last good scan result when relaunched ?

    Like any application. It can't handle it. It's not even the
    application's task to handle it. LMS would tell the operating system to
    save something to disk. If the OS fails to do so because of the
    powercut, then the database or file or whatever could be corrupted.

    Harddrive disconnection ? Are we talking external storage on NAS when the NAS or the network could fail ?

    If the music directory is not aviable when LMS starts , your dB will be invalid/dropped and you have to fix the problem so the files are aviable again and then do a rescan preferably a clear and rescan everything .

    What I donĺt know is LMS actions if the storage fails when we are up and running ?

    My best practice over the years with LMS has been to be sure that the hard drives with music is properly mounted before LMS starts .
    This is also why I never tried to have drives/directories mounted over WiFi or had several different NAS boxes this makes everything more complex and prone to mistakes and errors .
    Iĺm travel a lot in work so I power down stuff while away so most of of dB rebuilds have been me not starting everything properly or done to much experimenting and then forget about it two weeks later when I get home expecting to hear music .
