Cluster with shared storage - disk is always full?

    Hi Scott Atherton,

    I assume you haven't set up a limit per directory, and in that way each directory attempts to occupy as much data as possible until you hit the reserved space limit.

    Best practice is to allocate a certain volume to each directory, this can be configured in the NAS.

    Hey Norman,

    Correct, there is only a limit on the share, not per directory.

    As you suggested - a volume per directory is rather inefficient - as you'll likely be filling up one and not touching others. Is this where you would use a smaller volume per server, and backup the footage to another larger volume?

    Hi Scott Atherton,

    Sure, it is less efficient, but otherwise it would be undesirable for multiple reasons.

    The best thing you can do is allocate the desired amount of storage, let it run for the desired retention time and then check in the server setting what the average used bandwidth is and adjust the volume according to these averages.

    Two identical cameras with identical setting on two different scenes can consume much different bandwidth.

    I even recall a case where the difference was a factor 10. One camera was in a corner without traffic using ~0.2 Mbit/s, and the other was at a cash register using ~2 Mbit/s.
