Hi Jiri,
thanks for the feedback.
My main concern is if it's better to add each OSD one-by-one and wait
for the cluster to rebalance every time or do it all-together at once.
Furthermore an estimate of the time to rebalance would be great!
Regards,
George
Hi George,
List disks available:
# $ ceph-deploy disk list {node-name [node-name]...}
Add OSD using osd create:
# $ ceph-deploy osd create {node-name}:{disk}[:{path/to/journal}]
Or you can use the manual steps to prepare and activate disk
described at

Hi all!
I would like to expand our CEPH Cluster and add a second OSD node.
In this node I will have ten 4TB disks dedicated to CEPH.
What is the proper way of putting them in the already available
CEPH node?
I guess that the first thing to do is to prepare them with
ceph-deploy and mark them as out at preparation.
I should then restart the services and add (mark as in) one of
them. Afterwards, I have to wait for the rebalance
to occur and upon finishing I will add the second and so on. Is
this safe enough?
How long do you expect the rebalancing procedure to take?
I already have ten more 4TB disks at another node and the amount of
data is around 40GB with 2x replication factor.
The connection is over Gigabit.
Best,
George
