In practice, it's not a big deal. Just deploy your disks sequentially,
and Ceph will sort it out.
Sure, you'll waste a bit of time watching data copy to a new disk, only
to see it get remapped it to a newer disk. It's a small period of time
relative to how long it's going to take to remap to
There is no simultaneous support in ceph-deploy as this is something
that is not needed for users setting up a cluster to try out
ceph (the main objective of ceph-deploy)
However, there have been users that used scripts that can call
ceph-deploy in parallel so it might be possible to do so.

Hi, does ceph-deploy support to deploy osds simultaneously in a large scale
cluster? Looks mkcephfs does not support simultaneous osd deployment.
If there are many hosts with very large number and size of osds/devices, how do
I improve the performance to deploy the whole cluster at once?
