I have a simple PurgeWhenFull filter set up to keep the disk at 95% full, but I store the recordings on another disk. ZoneMinder accurately reports the second disk as "100%" in the top right, but the filter isn't kicking in because the OS drive with ZM on it is at 94%.
PurgeWhenFull should examine the disk space free on the volume holding the recordings folder, not the disk with the ZM app.
Is there any way I can work around this?
