Estou tentando instalar e implantar um cluster ceph. Como não tenho servidores físicos suficientes, crio 4 VMs no meu OpenStack usando a imagem oficial do Ubuntu 14.04. Desejo implementar um cluster com 1 nó monitor e 3 nós OSD com versão ceph 0.80.7-0ubuntu0.14.04.1
. Segui os passos do documento de implementação manual e instalei com êxito o nó do monitor. No entanto, após a instalação do nó do OSD, parece que os daemons do OSD estão em execução, mas não relatam corretamente ao nó do monitor. A árvore osd sempre mostra down
quando eu solicito o comando ceph --cluster cephcluster1 osd tree
.
A seguir estão os comandos e os resultados correspondentes que podem estar relacionados ao meu problema.
root@monitor:/home/ubuntu# ceph --cluster cephcluster1 osd tree

Embora o ceph OSD mostre up
normalmente ao mudar o ambiente do Ubuntu 14.04 para o CentOS 6.6 com as mesmas etapas de instalação, ainda espero resolver este problema já que estou mais familiarizado com o Ubuntu do que o CentOS.
Qualquer sugestão é apreciada. Muito obrigado!
