Não é possível adicionar o monitor inicial ao Ceph no Ubuntu

Question

Estou tentando configurar um cluster Ceph. Eu tenho 4 nós - 1 nó de administração, 1 monitor e 2 dispositivos de armazenamento de objetos. O guia de instalação que estou usando é fornecido no seguinte local: link .

Quando estou tentando adicionar o monitor inicial (etapa 5 no guia), estou recebendo o seguinte erro:

"worker-1-full" é o nó que estou tentando configurar como meu monitor. O comando que eu usei é:

"ceph-deploy mon create-initial". Por favor ajude. Obrigado antecipadamente!

    

Answer 1

Eu enfrentei os mesmos erros foi capaz de resolver o problema, adicionando o nome de host do meu outro nó ceph & IpAdrress e adicionando "public_network="

As seções que eu modifiquei no ceph.conf são:

mon_initial_members =
mon_host =
public_network =

cat /etc/ceph/ceph.conf

[global]
fsid = 33cb5c76-a685-469e-8cdd-fee7c98c3f4d
mon_initial_members = ceph1,ceph2
mon_host = 192.168.61.39,192.168.61.40
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx
filestore_xattr_use_omap = true
public_network = 192.168.61.0/24

E a execução do comando:

$ ceph-deploy --overwrite-conf mon create <ceph-node>

    

Answer 2

Parece que os nomes de seus nós diferem de seus nomes de host reais, de forma que o arquivo /var/run/ceph/ceph-mon.worker-1-full.asok tenha o nome incorreto. Eu tinha mudado o nome dos hosts e isso funcionou para mim.

    

Answer 3

O diretório / var / run / ceph existe? Se não, então o Ceph provavelmente não será capaz de criar o arquivo .asok (socket admin).

    

Answer 4

Você pode verificar o log MON em worker-1-full:/var/log/ceph/ceph-mon.worker-1-full.log . Se o MON não aparecer ou não puder criar o socket, algo deve estar logado lá.
