I've figured out but I'm scared from the result. The solution is "mon_osd_min_down_reporters = 1" Due to "two node" cluster and "replicated 2" with "chooseleaf host" the reporter count should be set to 1 but on a malfunction this could be a serious problem. Is there any better solution? by morphin <morphinwithyou@gmail.com>, 20 May 2021 Per, 22:04 tarihinde şunu yazdı:
Hello
I have a weird problem on 3 node cluster. "Nautilus 14.2.9" When I try power failure OSD's are not marking as DOWN and MDS do not respond anymore. If I manually set osd down then MDS becomes active again.
BTW: Only 2 node has OSD's. Third node is only for MON.
I've set mon_osd_down_out_interval = 0.3 in ceph.conf at global section and restart all MON's but when I check it with "ceph daemon mon.ID config show" I see mon_osd_down_out_interval: "600". I didn't get it why its still "600" and honestly I don't know even it has any effect on my problem.
Where should I check?
