Re: ceph osd crush move exception

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Hi,
can you share your 'ceph osd tree' so it easier to understand what might be going wrong. I didn't check the script in detail, what exactly do you mean by extending? Do you create new hosts in a different root of the osd tree? Do those new hosts get PGs assigned although they're in a different root? Has this worked before and it failed just this once? Does the failing MON recover or does it stay in a degraded state?

Hi

I have an OpenStack (pike) environment with a Ceph cluster (ceph version
12.2.5 luminous stable) deployed with kolla-ansible.

When I was scaling the Ceph cluster, I found a read/write exception on the
OpenStack VM.

( kolla-ansible uses the following script when expanding Ceph
https://github.com/openstack/kolla/blob/pike-eol/docker/ceph/ceph-osd/extend_start.sh
)

I ran 'ceph mon status' while checking the storage and found that ceph mon
was constantly electing.

I started to think it was a kolla issue, so I ran the script manually.
The problem was reproduced when I executed 'ceph osd crush move
192.168.1.47 root=default '.

I don't know if the logs of ceph mon can help to locate the problem.
