Luminous new OSD being over filled

[David C <dcsysengineer@xxxxxxxxx>]

Hi all

Trying to add a new host to a Luminous cluster, I'm doing one OSD at a time. I've only added one so far but it's getting too full.

The drive is the same size (4TB) as all others in the cluster, all OSDs have crush weight of 3.63689. Average usage on the drives is 81.70%

With the new OSD I start with a crush weight 0 and steadily increase. It's currently crush weight 3.0 and is 94.78% full. If I increase to 3.63689 it's going to hit too full.

It's been a while since I've added a host to an existing cluster. Any idea why the drive is getting too full? Do I just have to leave this one with a lower crush weight and then continue adding the drives and then eventually even out the crush weights?

Thanks

David
