Hi We’ve recently encountered the following errors: [WRN] OSD_SLOW_PING_TIME_BACK: Slow OSD heartbeats on back (longest 2752.832ms) Slow OSD heartbeats on back from osd.2 [nvme-a] to osd.290 [nvme-c] 2752.832 msec ... Truncated long network list. Use ceph daemon mgr.# dump_osd_network for more information To get more information we wanted to run the dump_osd_network command, but it doesn’t seem to be a valid command: ceph daemon /var/run/ceph/ceph-mgr.$(hostname).asok dump_osd_network 0 no valid command found; 10 closest matches: 0 1 2 abort assert config diff config diff get <var> config get <var> config help [<var>] config set <var> <val>... admin_socket: invalid command Other commands, like ceph daemon dump_cache work, so it seems to hit the right socket. What am I doing wrong? Cheers, Denis
