Crash dump is being written to: /var/log/rabbitmq/erl_crash.dump...done
修复方法:
(1) 找到 rabbitmq 使用的 pv，例如: rabbitmq-0 的 pod:
# kubectl get pv | grep rabbitmq-0
pvc-70ed48bf-bef8-4658-b530-1fd3a6ef5937 200Gi RWO Delete Bound openstack/rabbitmq-data-rabbitmq-0 ceph-ssd 6d17h
(2) 找到 pv 使用的信息:
# kubectl get pv pvc-70ed48bf-bef8-4658-b530-1fd3a6ef5937 -o yaml

(3) 在 pod 节点上查看对应的物理设备
# ssh node-2 rbd showmapped | grep kubernetes-dynamic-pvc-c8a3585f-dc7b-438c-a22e-cca9d84c341f
0 ssdpool kubernetes-dynamic-pvc-c8a3585f-dc7b-438c-a22e-cca9d84c341f - /dev/rbd0
(4) 查看设备挂载目录
# ssh node-2 mount | grep rbd0
/dev/rbd0 on /var/lib/kubelet/plugins/kubernetes.io/rbd/mounts/ssdpool-image-kubernetes-dynamic-pvc-c8a3585f-dc7b-438c-a22e-cca9d84c341f type ext4 (rw,relatime,stripe=1024)
/dev/rbd0 on /var/lib/kubelet/pods/3a37e264-4fd5-4cb8-844b-6b6cd4a6859c/volumes/kubernetes.io~rbd/pvc-70ed48bf-bef8-4658-b530-1fd3a6ef5937 type ext4 (rw,relatime,stripe=1024)
(5) 查找 wal 文件路径，查找的路径来自步骤 (4)
# ssh node-2 find /var/lib/kubelet/pods/3a37e264-4fd5-4cb8-844b-6b6cd4a6859c/volumes/kubernetes.io~rbd/pvc-70ed48bf-bef8-4658-b530-1fd3a6ef5937 -name "*.wal"
/var/lib/kubelet/pods/3a37e264-4fd5-4cb8-844b-6b6cd4a6859c/volumes/kubernetes.io~rbd/pvc-70ed48bf-bef8-4658-b530-1fd3a6ef5937/mnesia/rabbit@rabbitmq-0.rabbitmq-discovery.openstack.svc.cluster.local/quorum/rabbit@rabbitmq-0.rabbitmq-discovery.openstack.svc.cluster.local/00000025.wal
(6) 删除 wal 文件
此步骤请慎重操作，建议将文件备份后再操作。
# ssh node-2 rm -rf /var/lib/kubelet/pods/3a37e264-4fd5-4cb8-844b-6b6cd4a6859c/volumes/kubernetes.io~rbd/pvc-70ed48bf-bef8-4658-b530-1fd3a6ef5937/mnesia/rabbit@rabbitmq-0.rabbitmq-discovery.openstack.svc.cluster.local/quorum/rabbit@rabbitmq-0.rabbitmq-discovery.openstack.svc.cluster.local/00000025.wal
Warning: Permanently added 'node-2' (ED25519) to the list of known hosts.
(7) 删除 pod，重新启动 pod
# kubectl delete pods rabbitmq-0 -n openstack
pod "rabbitmq-0" deleted
等待 pod 再次启动，过一会重新数据同步恢复。
