CEPH Expansion

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

 



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
