Re: ceph osd create XX

[Stefan Priebe <s.priebe@profihost.ag>]

Hi Greg,

thanks for explanation. I'm using current next branch.

I'm using:
host1:
osd 11 .. 14
host2:
osd 21 .. 24
host3:
osd 31 .. 34
host4:
osd 41 .. 44
host5:
osd 51 .. 54

Right now i want to add host6. But i still don't know even with your 
explanation how to add osd 61-64 to osdmap.
