Hi All, Is there a way to prepare the drives of multiple OSD and then bring them into the CRUSH map all at once?
Right now I'm using: ceph-deploy --overwrite-conf disk prepare --zap-disk $NODE:$DEV </dev/null ceph-deploy disk activate $NODE:$DEV </dev/null and have noticed that each successive format gets slower and slower as the other OSDs become active on the node. I'd hoped to keep the OSDs quiet so that the formats would proceed quickly, then turn them all on at once. I've tried "ceph osd reweight osdnum 0" for the new OSDs and that appears to keep them from being written. However, there are preexisting OSDs on the node and they start churning like mad, slowing down the formats of the other drives anyway. (Looks like my controller cannot actually handle all drives at maximum usage.) Thanks for the help!
