這篇文章給大家分享的是有關 ceph 集群安裝報錯怎么辦的內容。丸趣 TV 小編覺得挺實用的，因此分享給大家做個參考，一起跟隨丸趣 TV 小編過來看看吧。
1. 創建密鑰時報錯
[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
解決方法:
[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 認證權限問題
[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
解決方法:
[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 顯示沒有激活 mgr
[root@node1 ~]# ceph health
HEALTH_WARN no active mgr
[root@node1 ~]#
解決方法:
[root@node1 ~]# ceph-deploy mgr create node1 node2 node3 – 創建 mgr 進程
[root@node1 ~]# ceph health
HEALTH_OK
[root@node1 ~]# ceph mgr metadata
4. 安裝好 ceph 后系統重啟報錯 (進入不了終端)
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
解決方法:
注釋 osd 磁盤分區, 不能將 osd 分區掛載, 否則會進入不了系統, 也可在分區的 defaults 后面加入 nofail 參數, 用逗號隔開
[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
UUID=2096e465-9251-4dd7-93c7-a163adba6209 / xfs defaults 0 0
UUID=76236dfd-510d-4d33-9071-3f2ecfeee3f7 /boot xfs defaults 0 0
#UUID=zDLnfa-iAwr-yp1k-C19m-8oOC-iLmS-agJarY /data ext4 defaults 0 0 – 注釋 osd 磁盤分區, 不能掛載

[root@node2 ~]#
