Hi all,

I know Ceph offers a way to 'automatically' cause blank drives it 
detects to be spun up into osds, but I think that's an 'all or nothing' 
situation if I read the docs properly.

Is there a way to specify which slots, or even better, a way to specify 
not specific slots?   It sure would be nice to tell ceph 'it owns these 
drive slots on those hosts, and if ever there is a blank drive in there, 
assume the previous one if any is never coming back to that slot, and 
the new one should be auto-installed as an osd' without having to get 
involved in typing or clicking anything.

The reason is-- some hosts boot off the same controller as the osds use, 
I don't want a replacement boot drive getting spun into an osd.

Thanks

Harry
