Hi all, I have startet the ceph-cluster with an weight of 1 for all osd-disks (4TB). Later I switched to ceph-deploy and ceph-deploy use normaly an weight of 3.64 for this disks, which makes much more sense!
Now I wan't to change the weight of all 52 osds (on 4 nodes) to 3.64 and the question is, how to proceed on an productional cluster? Increase all 52 weights in 0.1-steps, wait for an calm system and do it again till 3.64 is reached? Or modify the crushmap (export, decompile, change, compile, load) directly from 1 to 3.64? Is in this case the data accessible? Are OSDs with 76% data an problem in this scenario? I have learned, that ceph really don't like full disks ;-) Any hints?
