The other thing I discovered is not to wait between steps; some changes result in a new
crushmap, that then triggers replication. You want to speed through the step

OK - although obviously if you're going to make a disk with a label
ost=ha1
Check to make sure it's added.
ceph osd tree
Start up the new osd, and let it sync with the cluster.

I'm just finding my way around the Ceph documentation. What I'm hoping
to build are servers with 24 data disks and one O/S disk. From what I've
