Greetings All, I recently started working with our ceph cluster here and have been reading about weighting.
It appears the current best practice is to weight each OSD according to it’s size (3.64 for 4TB drive, 7.45 for 8TB drive, etc). As it turns out, it was not configured this way at all; all of the OSDs are weighted at 1. So my questions are: Can we re-weight the entire cluster to 3.64 and then re-weight the 8TB drives afterwards at a slow rate which won’t impact performance? If we do an entire re-weight will we have any issues? Would it be better to just reweight the 8TB drives to 2 gradually? Any and all suggestions are welcome. Cheers, Mike Cave
