Re: strange OSD status when rebooting one server

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



You have hosts in the crush map with no OSDs. They are out+down and will be counted while other hosts are also down. It will go back to normal when you start the host with disks again. If you delete the hosts with no disks, you will probably see misplaced objects. Why are they there in the first place? Are you planning to add hosts or are these replaced ones?
