Hello,
Just an advise : next time, I will extend my Jewel ceph cluster with a
fourth node.
Actually, we have 3 x nodes of 12 x OSD with 4TB DD (36 x DD 4TB).
I will add a new node with 12 x 8TB DD (will add 12 new OSD => 48 OSD).
So, how to simply equilibrate ?
How to just unplug 3 x DD 4TB per node and add to fourth node and just
plug 3 x 8TB in each node coming from fourth node ?
I want at the end : 3 x DD 8TB per node and 9 x DD 4TB per node ?
How to do that in the easyest way ?
I don't want move all data : It will take a long time per OSD...
Is there a way to just switch OSD between node ?
Thanks for your help.
