Hi, I am trying to deploy Ceph Quincy using ceph-ansible on Rocky9. I am having some problems and I don't know where to search for the reason. PS : I did the same deployment on Rocky8 using ceph-ansible for the Pacific version on the same hardware and it worked perfectly. I have 03 controllers nodes : mon, mgr, mdss and rgws and 27 osd nodes : with 04 nvme disks (osd) each I am using a 10Gb network with jumbo frames. The deployment starts with no issues, the 03 monitors are created correctly, then the 03 managers are created, after that the OSD are prepared and formatted, until here everything is working fine, but when the "*wait for all osd to be up*" task is launched, which means starting all OSDs containers in all OSD nodes, things go south, the monitors become out of quorum, ceph -s takes a lot of time to respond and not all OSDs are being activated, and the deployment fails at the end. cluster 2023-03-06T12:00:26.431947+0100 mon.controllera (mon.0) 3864 : cluster [WRN] [WRN] MON_DOWN: 1/3 mons down, quorum controllera,controllerc cluster 2023-03-06T12:00:26.431953+0100 mon.controllera (mon.0) 3865 : cluster [WRN] mon.controllerb (rank 1) addr [v2: 20.1.0.27:3300/0,v1:20.1.0.27:6789/0] is down (out of quorum) The monitor container in 2 of my controllers nodes stays at 100% of cpu utilization.

If yes, how may I find this? thanks in advance. Regards.
