Ceph重建Mon节点

公司Ceph集群一mon节点死活启动不起来，翻遍了日志和多项资料未能找到原因。只能重建节点。

cd /var/lib/ceph/mon
cp -rp ceph-master-10-24-65-107/ ceph-master-10-24-65-107-bak/
ceph mon getmap -o /tmp/monmap
cp -a ceph-master-10-24-65-107/keyring /tmp/keyring
rm -rf ceph-master-10-24-65-107/
ceph-mon --cluster ceph --id master-10-24-65-107 --mkfs --monmap /tmp/monmap --keyring /tmp/keyring
chown -R ceph:ceph ceph-master-10-24-65-107
