1. Error creating key Times

[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

Solution:

[root@node1 ~] # systemctl stop firewalld

[root@node1 ~] # systemctl disable firewalld

Removed symlink / etc/systemd/system/multi-user.target.wants/firewalld.service.

two。 Authentication permission issues using ceph

[root@node1] # / bin/ceph-- cluster=ceph osd stat-- format=json

2019-04-25 09 unable to find a keyring on 1631.404 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 7f5a501ac700 1631 404 7f5a501ac700-1 monclient: ERROR: missing keyring, cannot use cephx for authentication

[errno 2] error connecting to the cluster

Solution:

[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. Use ceph health to show that mgr is not activated

[root@node1 ~] # ceph health

HEALTH_WARN no active mgr

[root@node1 ~] #

Solution:

[root@node1 ~] # ceph-deploy mgr create node1 node2 node3-- create a mgr process

[root@node1 ~] # ceph health

HEALTH_OK

[root@node1 ~] # ceph mgr metadata

4. Restart the system after installing ceph (unable to enter the terminal)

Restarting network (Via systemctl): Error getting authority: Error initializing authority: Could not connect: No such file or directory

Welcome to emergency moored after 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

Solution:

Note the osd disk partition. You cannot mount the osd partition, otherwise you will not be able to enter the system. You can also add the nofail parameter after the defaults of the partition and separate it with a comma.
