No, I did not think anything fancy [global] cluster network = 10.152.40.0/22 fsid = a6baa789-6be2-4ce0-ab2d-7c78b899d4bd mon host = 10.152.28.171,10.152.28.172,10.152.28.173 mon initial members = osd01,osd02,osd03 osd pool default crush rule = -1 public network = 10.152.28.0/22 I just tried to start the mon with force-sync but as the mon did not join it will not pull any data ceph-mon -f --cluster ceph --id osd01 --setuser ceph --setgroup ceph --debug_mon 10 --yes-i-really-mean-it --force-sync -d I can try to move the /var/lib/ceph/mon/ dir and recreate it!? thanks for all the help so far!
