一、基本操作
ceph osd tree //查看所有osd情况 其中里面的weight就是CRUSH算法要使用的weight#xff0c;越大代表之后PG选择该osd的概率就越大
ceph -s //查看整体ceph情况 health_ok才是正常的
ceph osd out osd.1 //将osd.1踢出集群
ceph osd i…Ceph运维笔记
一、基本操作
ceph osd tree //查看所有osd情况 其中里面的weight就是CRUSH算法要使用的weight越大代表之后PG选择该osd的概率就越大
ceph -s //查看整体ceph情况 health_ok才是正常的
ceph osd out osd.1 //将osd.1踢出集群
ceph osd in osd.1 //将out的集群重新加入集群
ceph osd df tree //能够得到osd更加详细的信息利用率这些二、问题解决
1.执行ceph-deploy mon create-initial出错
echo deb [arch$(dpkg --print-architecture) signed-by/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable | tee /etc/apt/sources.list.d/docker.list /dev/null解决方法
2.osd down先尝试重启
ceph osd tree //先查看down掉的osd编号 假设down掉的是osd.1ceph osd out osd.1 //在部署节点执行 先将osd.1移出集群 systemctl stop ceph-osd1.serviceceph-osd -i 1 //在osd所在节点执行
3.Resource temporarily unavailable和is another process using it?
[ceph1][WARNIN] E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
[ceph1][WARNIN] E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?sudo rm /var/lib/dpkg/lock //直接把锁删了4.重启osd无效 直接删除osd 重新创建
ceph osd out 1 //将osd.1踢出集群执行ceph auth del osd.1 和 ceph osd rm 1, 此时删除成功但是原来的数据和日志目录还在也就是数据还在执行umount /dev/sdb,然后执行ceph-disk zap /dev/sdb将数据也删除了之后再创建新osd时必须是在一个空磁盘上创建
ceph-deploy osd create --data /dev/vdc ceph1
5.application not enabled on 1 pool(s)
