Hello,
i was debugging ceph and saw this in syslog
Code: 
Sep 20 08:39:31 pve3 ceph-osd[195290]: 2019-09-20 08:39:31.086 7fae4e99f700 -1 osd.3 148374 set_numa_affinity unable to identify public interface 'bond2' numa node: (2) No such file or directory
Sep 20 08:39:31 pve3 ceph-osd[195291]: 2019-09-20 08:39:31.090 7fb238859700 -1 osd.2 148373 set_numa_affinity unable to identify public interface 'bond2' numa node: (2) No such file or directory

is that harmless?

It seems to be harmless. Here is a Ceph bug report, someone else already reported the issue in our (german) forum.
 
Hello,

I've got similar thing:
Code: 
root@pk09:~# journalctl -u ceph-osd@6.service | grep numa
lut 26 02:38:20 pk09 ceph-osd[1745]: 2025-02-26T02:38:20.555+0100 74ed64dba6c0 -1 osd.6 2372 set_numa_affinity unable to identify public interface '' numa node: (2) No such file or directory
lut 26 03:08:59 pk09 ceph-osd[1745]: 2025-02-26T03:08:59.395+0100 74ed64dba6c0 -1 osd.6 2385 set_numa_affinity unable to identify public interface '' numa node: (2) No such file or directory

which is related to OSD flapping:
Code: 
root@pk09:~# dmesg -T | grep osd6
[śro lut 26 02:37:53 2025] libceph (10028f5a-d813-4d16-a4ae-bbcc250e6a19 e2370): osd6 down
[śro lut 26 02:38:23 2025] libceph (10028f5a-d813-4d16-a4ae-bbcc250e6a19 e2373): osd6 up
[śro lut 26 03:08:55 2025] libceph (10028f5a-d813-4d16-a4ae-bbcc250e6a19 e2383): osd6 down
[śro lut 26 03:09:02 2025] libceph (10028f5a-d813-4d16-a4ae-bbcc250e6a19 e2386): osd6 up

But I do not have a clue how to debug what's wrong.
It happens during the backup window (when load on a ceph cluster is significantly higher than usual).
