1.创建密钥时报错
[root@node1 ~]# ceph-deploy gatherkeys node1
[node1][DEBUG ] get remote short hostname
[node1][DEBUG ] fetch remote file
[node1][INFO ] Running command: /usr/bin/ceph --connect-timeout=25 --cluster=ceph --admin-daemon=/var/run/ceph/ceph-mon.node1.asok mon_status
[node1][ERROR ] Not yet quorum for 'node1'
[ceph_deploy.gatherkeys][ERROR ] Failed to connect to host:node1
[ceph_deploy.gatherkeys][INFO ] Destroy temp directory /tmp/tmpMfWp77
[ceph_deploy][ERROR ] RuntimeError: Failed to connect any mon
解决方法:
[root@node1 ~]# systemctl stop firewalld
[root@node1 ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
[root@node1 ~]# ceph-deploy --overwrite-conf mon create-initial
2.使用ceph认证权限问题
[root@node1 ~]# /bin/ceph --cluster=ceph osd stat --format=json
2019-04-25 09:16:31.404 7f5a501ac700 -1 auth: unable to find a keyring on /etc/ceph/ceph.client.admin.keyring,/etc/ceph/ceph.keyring,/etc/ceph/keyring,/etc/ceph/keyring.bin,: (2) No such file or directory
2019-04-25 09:16:31.404 7f5a501ac700 -1 monclient: ERROR: missing keyring, cannot use cephx for authentication
[errno 2] error connecting to the cluster
解决方法:
[root@node1 ~]# find / -name ceph.client.admin.keyring
/root/ceph.client.admin.keyring
[root@node1 ~]# cp -a /root/ceph.client.admin.keyring /etc/ceph/
[root@node1 ~]# chmod +r ceph.client.admin.keyring
[root@node1 ~]# /bin/ceph --cluster=ceph osd stat --format=json
{"epoch":7,"num_osds":1,"num_up_osds":1,"num_in_osds":1,"full":false,"nearfull":false,"num_remapped_pgs":0}
[root@node1 ~]# ceph health
HEALTH_WARN no active mgr
[root@node1 ~]#
3.使用ceph health显示没有激活mgr
[root@node1 ~]# ceph health
HEALTH_WARN no active mgr
[root@node1 ~]#
解决方法:
[root@node1 ~]# ceph-deploy mgr create node1 node2 node3 --创建mgr进程
[root@node1 ~]# ceph health
HEALTH_OK
[root@node1 ~]# ceph mgr metadata
4.安装好ceph后系统重启报错(进入不了终端)
Restarting network (Via systemctl): Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark,1)
Welcome to emergency mode!Aftle logging in,type "journalcel -xb" to view
system logs,"systemctl reboot" to reboot,"systemctl default" or ^D to
try again to boot into default mode.
Give root password for maintenance
( Control-D )
login incorrect
解决方法:
注释osd磁盘分区,不能将osd分区挂载,否则会进入不了系统,也可在分区的defaults后面加入nofail参数,用逗号隔开
[root@node2 ~]# cat /etc/fstab
# /etc/fstab
# Created by anaconda on Wed Apr 24 20:17:43 2019
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
