ceph 安装ceph问题汇总

1、在不同节点安装ceph时，出现以下异常：
参考这里

ceph deploy RuntimeError: NoSectionError: No section: ‘ceph‘

解决方法：

在报错的机器上尝试：
yum remove ceph-release
rm  /etc/yum.repos.d/ceph.repo.rpmsave

执行以后再执行

ceph-deploy install admin  node1 node2 node3

2、ceph用户没有权限
**执行激活osd盘时出现 **

ceph-deploy osd activate node2:/var/local/osd0 node3:/var/local/osd1

[node3][WARNIN] ceph_disk.main.Error: Error: [‘ceph-osd‘, ‘--cluster‘, ‘ceph‘, ‘--mkfs‘, ‘--mkkey‘, ‘-i‘, ‘1‘, ‘--monmap‘, ‘/var/local/osd1/activate.monmap‘, ‘--osd-data‘, ‘/var/local/osd1‘, ‘--osd-journal‘, ‘/var/local/osd1/journal‘, ‘--osd-uuid‘, ‘ee9c4a6c-e2b5-46cd-9e91-fd5d6f36fd57‘, ‘--keyring‘, ‘/var/local/osd1/keyring‘, ‘--setuser‘, ‘ceph‘, ‘--setgroup‘, ‘ceph‘] failed : 2016-08-31 16:38:58.909449 7f48adbb7800 -1 filestore(/var/local/osd1) mkfs: write_version_stamp() failed: (13) Permission denied

[node3][ERROR ] RuntimeError: command returned non-zero exit status: 1
[ceph_deploy][ERROR ] RuntimeError: Failed to execute command: /usr/sbin/ceph-disk -v activate --mark-init systemd --mount /var/local/osd1

解决方法

chown ceph:ceph  /var/local/osd0
chown ceph:ceph  /var/local/osd1

 

创建成功ceph健康状况良好

3、RuntimeError: bootstrap-rgw keyring not found; run ‘gatherkeys‘

root@admin ceph]# ceph-deploy rgw create node2
[ceph_deploy.conf][DEBUG ] found configuration file at: /root/.cephdeploy.conf
[ceph_deploy.cli][INFO  ] Invoked (1.5.34): /usr/bin/ceph-deploy rgw create node2

[ceph_deploy.cli][INFO  ]  rgw                           : [(‘node2‘, ‘rgw.node2‘)]

[ceph_deploy.rgw][DEBUG ] Deploying rgw, cluster ceph hosts node2:rgw.node2
[ceph_deploy][ERROR ] RuntimeError: bootstrap-rgw keyring not found; run ‘gatherkeys‘

执行如下命令解决

ceph-deploy gatherkeys node2
