Ceph » Orchestrator

Bug #38757

Updated by Sebastian Wagner about 5 years ago

I installed ceph-mgr-ssh-14.1.1 and python-remoto-0.0.35 

 set the ssh moudule by  

 "ceph mgr module enable ssh" 

 "ceph orchestrator set backend ssh" 

 then 

 I add the ssh_config_file as the follows: 
 <pre> 
 

 Host node6 
   HostName 192.168.10.3 
   User root 
   Port 22 
   UserKnownHostsFile /root/.ssh/known_hosts 
   StrictHostKeyChecking no 
   PasswordAuthentication no 
   IdentityFile /root/.ssh/id_rsa 
   IdentitiesOnly yes 
   LogLevel FATAL 
 </pre> 

 it is the format as vagrant ssh-config, 

 "ceph ssh set-ssh-config -i ssh_config_file" 

 the I add node6 by   

 ceph orchestrator host add node6 

 then I tried to ls devices on node6. 

 the    http://docs.ceph.com/docs/master/mgr/orchestrator_cli/ shows that 

 "host add, host ls, host rm ,mgr update, mon update,osd create,device ls" are already supported. 

 but it throws an error. 
 <pre> 
 

 [root@node6 ~]# ceph orchestrator device ls --host=node6
