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
