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. Pascal, |
