Hello Janne,
We only have a single network configured for our OSDs:
```sh ceph config get osd public_network172.20.180.0/24
ceph config get osd cluster_network172.20.180.0/24 ```
However, in the output of ceph health detail, we see multiple networks being checked:
```sh ceph health detail HEALTH_OK (muted: OSD_UNREACHABLE) (MUTED, STICKY) [ERR] OSD_UNREACHABLE: 32 osds(s) are not reachable osd.0's public address is not in '172.20.180.1/32,172.20.180.0/24' subnet ```
We are unsure where 172.20.180.1/32 is coming from.
Any ideas on where to look next? Thanks for your response.
Hi, Have you check for 172.20.180.1/32 in ceph.conf files? Regards, Frédéric.

Hello everyone,
After upgrading our Ceph cluster from 17.2.7 to 17.2.8 using `cephadm`, all OSDs are reported as unreachable with the following error:
``` HEALTH_ERR 32 osds(s) are not reachable [ERR] OSD_UNREACHABLE: 32 osds(s) are not reachable osd.0's public address is not in '172.20.180.1/32,172.20.180.0/24' subnet osd.1's public address is not in '172.20.180.1/32,172.20.180.0/24' subnet ... osd.31's public address is not in '172.20.180.1/32,172.20.180.0/24' subnet ```
However, all OSDs actually have IP addresses within the ` 172.20.180.0/24` <http://172.20.180.0/24> subnet. The cluster remains functional (CephFS is accessible), and muting the warning with `ceph health mute OSD_UNREACHABLE --sticky` allows normal operation, but the underlying issue persists.
### **Questions** 1. Has anyone else encountered this issue after upgrading to 17.2.8?
Yes, we ran into it also. It "only" reads the first entry and skips the second (and third and so on)
2. Is this a known regression? (This seems similar to issue #67517.) 3. Would upgrading to Ceph 18.x (Reef) resolve the problem? 4. Is there any solution other than muting the health warning?
We widened the netmask to cover both nets so we would have them in one definition.
