Hi Harry, It's a inoffensive bug [1] related to IPv6 clusters. It will be fixed in v19.2.2. The workaround is to mute the error with 'ceph health mute ...'. It's all you can do for now. Regards, Frédéric. ________________________________ De : Harry G Coin <hgcoin@gmail.com> Envoyé : vendredi 7 février 2025 22:52 À : ceph-users Objet : [ceph-users] 19.2.1: HEALTH_ERR 27 osds(s) are not reachable. (Yet working normally...) 19.2.1 complains of all osd's being unreachable, as their public address isn't in the public subnet. However, they all are within the subnet, and are working normally as well. It's embarrassing for the dashboard to glow red of a totally crippled osd roster --- while all is working normally. This existed in the previous, but was working prior to 19. Detail: Notice, for osd.0, the dashboard lists public_addr [fc00:1002:c7::44]:6807/4160993080 But, we have in the logs: 7/2/25 03:35 PM[ERR] osd.0's public address is not in 'fc00:1002:c7::/64' subnet 7/2/25 03:35 PM[ERR][ERR] OSD_UNREACHABLE: 27 osds(s) are not reachable 7/2/25 03:35 PM[ERR]Health detail: HEALTH_ERR 27 osds(s) are not reachable However, as per the osd.0 attributes, the public address for osd.0 is well inside the stated public subnet. All the osd's are similarly configured, working, and held to be unreachable at the same time, for the same reason. Tell me there's a way to fix this without waiting a further half year.... _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
