I finally received approval to upgrade our old firefly(0.8.7) cluster to Luminous. I started the upgrade, upgrading to hammer(0.94.10), then jewel(10.2.11), but after jewel, I ran the “ceph osd crush tunables optimal” command, then “ceph –s” command showed 60% of the objects were misplaced. Now the cluster is just churning while it does the recovery for that. Is this something that happens when upgrading from firefly up? I had done a hammer upgrade to Jewel before, no rebalance occurred after issuing that command. Regards, -Brent Existing Clusters: Test: Luminous 12.2.10 with 3 osd servers, 1 mon/man, 1 gateway ( all virtual ) US Production: Jewel 10.2.11 with 5 osd servers, 3 mons, 3 gateways behind haproxy LB UK Production: Luminous 12.2.10 with 15 osd servers, 3 mons/man, 3 gateways behind haproxy LB US Production all SSD: Luminous 12.2.10 with 6 osd servers, 3 mons/man, 3 gateways behind haproxy LB |
