[ceph-users] Reclassify crush map

Hi all, I want to reclassify my crushmap. I have two roots, one hiops and one default. In hiops root I have one datacenter and in that I have three rack and in each rack I have 3 osds. When I run the command below it says "item -55 in bucket -54 is not also a reclassified bucket". I see the new crushmap before reclassify-bucket command and item -55 was for my datacenter! What should I do? If I reclassify my datacenter I will lose my datacenter! crushtool -i crush-map --reclassify \ --reclassify-root default hdd \ --set-subtree-class default hdd \ --reclassify-root hiops ssd \ --reclassify-bucket hiops ssd default \ -o new-crush-map Thanks
