It's easy. The problem ise OSD's are still up because there is not enough down mon_osd_min_down_reporters and due to this problem MDS is stucking. 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. In LAB environment you're fine. nORKy <joff.au@gmail.com>, 15 Haz 2021 Sal, 16:18 tarihinde şunu yazdı:
Hi,
I'm building a lab with virtual machines.
I build a set up with only 2 nodes, 2 osd per nodes and I have a host that use mount.cephfs Each 2 ceph nodes runs services mon + mgr + mds and has cephadm command.
If I stop a node, all commands hang. Can't use dashboard, can't use ceph -s or any ceph command, and my cephfs on the third host stop to respond too (ex: with ls command) All come back, when I power on the stopped node
Why is there no failover ??
Thanks you
