Dear all Today I realized that the syslog on the mon/mgr modules was complaining about missing credentials for the crash client So. following what is reported in: https://docs.ceph.com/en/quincy/mgr/crash/ I did: root@ceph-mon-01 ~]# ceph auth get-or-create client.crash mon 'profile crash' mgr 'profile crash' [client.crash] key = AQAqNKtmny3yNRAALoVRCgPju2Epc+BPfqOSdw== and on the 3 mon/mgr nodes I created the file /etc/ceph/ceph.client.crash.keyring root@ceph-mon-01 ~]# ll /etc/ceph/ceph.client.crash.keyring -rw-r--r-- 1 ceph ceph 64 Aug 1 09:21 /etc/ceph/ceph.client.crash.keyring [root@ceph-mon-01 ~]# cat /etc/ceph/ceph.client.crash.keyring [client.crash] key = AQAqNKtmny3yNRAALoVRCgPju2Epc+BPfqOSdw== But it is still complaining in the syslog [*] Do I need to also create a client.crash.$hostname ? I have to admit that the doc is not fully clear to me .... At any rate now ceph shows: [root@ceph-mon-01 ~]# ceph health detail HEALTH_WARN 8 mgr modules have recently crashed [WRN] RECENT_MGR_MODULE_CRASH: 8 mgr modules have recently crashed mgr module k8sevents crashed in daemon mgr.ceph-mon-01 on host ceph-mon-01.cloud.pd.infn.it at 2024-07-23T08:53:52.543451Z mgr module k8sevents crashed in daemon mgr.ceph-mon-01 on host ceph-mon-01.cloud.pd.infn.it at 2024-07-23T09:09:17.703402Z mgr module k8sevents crashed in daemon mgr.ceph-mon-02 on host ceph-mon-02.cloud.pd.infn.it at 2024-07-22T13:44:18.779525Z mgr module k8sevents crashed in daemon mgr.ceph-mon-02 on host ceph-mon-02.cloud.pd.infn.it at 2024-07-22T13:57:24.207309Z mgr module k8sevents crashed in daemon mgr.ceph-mon-03 on host ceph-mon-03.cloud.pd.infn.it at 2024-07-22T10:42:42.002880Z mgr module k8sevents crashed in daemon mgr.ceph-mon-03 on host ceph-mon-03.cloud.pd.infn.it at 2024-07-22T11:09:21.639576Z mgr module k8sevents crashed in daemon mgr.ceph-mon-03 on host ceph-mon-03.cloud.pd.infn.it at 2024-08-01T06:02:01.139099Z mgr module k8sevents crashed in daemon mgr.ceph-mon-03 on host ceph-mon-03.cloud.pd.infn.it at 2024-08-01T07:45:16.249664Z but that module is disabled [**].
