Reserving a disk for evacuation

[BlueDragon]

Hi,
Is there a way to set a pool of say 5 drives, have 4 of them work as normal but leave the 5th empty in case scanner detects a problem and evacuates a drive? Essentially leave it empty for an emergency.
Thanks

A way to do it would be Manage Pool -> Balancing -> Settings -> tick "File placement rules respect real-time file placement limits set by the balancing plug-ins", then Manage Pool -> Balancing -> File Placement -> add a Rule for "*" with all drives ticked except the one you want to leave empty.
