Hi,

I am delving into the world of ceph for the first time and seem to have a problem, running pacific with a 3 node cluster of nucs

Code: 
May 25 19:38:50 nuc0 ceph-crash[741]: WARNING:ceph-crash:post /var/lib/ceph/crash/2023-05-23T22:17:58.511383Z_168f48ae-991d-46f3-9836-7103411602f6 as client.crash.nuc0 failed: Error initializing cluster client: ObjectNotFound('RADOS object not found (error calling conf_read_file)')

Any help with this problem or how to figure out what the issue is would be greatly appreciated.

Thanks
 
Ok I see whats going on.

Something is trying to use the ceph orch command.

Code: 
    "backtrace": [
        "  File \"/usr/share/ceph/mgr/nfs/module.py\", line 169, in cluster_ls\n    return available_clusters(self)",
        "  File \"/usr/share/ceph/mgr/nfs/utils.py\", line 38, in available_clusters\n    completion = mgr.describe_service(service_type='nfs')",
        "  File \"/usr/share/ceph/mgr/orchestrator/_interface.py\", line 1488, in inner\n    completion = self._oremote(method_name, args, kwargs)",
        "  File \"/usr/share/ceph/mgr/orchestrator/_interface.py\", line 1555, in _oremote\n    raise NoOrchestrator()",
        "orchestrator._interface.NoOrchestrator: No orchestrator configured (try `ceph orch set backend`)"
    ],

How can I stop proxmox doing this, my understanding is proxmox should not have this enabled but something is trying use it?

Click to expand...
Did you install ceph dashboard ? (its not default) might come from that?

The symlink exists and enabling the CEPH dashboard on all mgr nodes did not solve it unfortunately.

Code: 
root@pve01:~# ls -al /etc/ceph/ceph.conf
lrwxrwxrwx 1 root root 18 Mar  4  2019 /etc/ceph/ceph.conf -> /etc/pve/ceph.conf

Could someone please advise how to fix this. Many Thanks.
