I have built the ceph source code and make it installed with the following commands:

apt-get install a series of dependency packages
./autogen.sh
./configure
make
make install

All these processes went well. When I type:

which ceph

Console shows:

/usr/local/bin/ceph

So I think I have install ceph successfully. But when I try to start the ceph-mon daemon, console tells me:

start: unknown job: ceph-mon

And I have checked my service list by typing:

initctl list | grep ceph

And the output is blank.

Somebody could tell me why?

can you run cepn-mon -i <your-mon-id>, I solve this by :

(I am at the same situation as yours, I am based on firefly & I compile & make install from the cource code.)

#!/bin/bash                                                                     
fsid=`uuidgen`                                                                  
host="your-mon-host"                                                                  
ipaddr="your-mon-ip-addr"                                                              

echo "[global]" > ./ceph.sample.conf                                            
echo "fsid = ${fsid}" >> ./ceph.sample.conf                                     
echo "mon initial members=${host}" >> ./ceph.sample.conf                        
echo "mon host = ${ipaddr}" >> ./ceph.sample.conf                               
cat ./popular_settings.txt >> ./ceph.sample.conf                                
cp ./ceph.sample.conf /etc/ceph/ceph.conf                                       

rm -rf /var/lib/ceph/mon/ceph-${host}/done                                      

sudo ceph-authtool --create-keyring /var/lib/ceph/tmp/ceph-${host}.mon.keyring --gen-key -n mon. --cap mon 'allow *'
sudo ceph-authtool --create-keyring /etc/ceph/ceph.client.admin.keyring --gen-key -n client.admin --set-uid=0 --cap mon 'allow *' --cap osd 'a    llow *' --cap mds 'allow'

sudo chmod +r /var/lib/ceph/tmp/ceph-${host}.mon.keyring                        
sudo chmod +r /etc/ceph/ceph.client.admin.keyring                               

sudo ceph-authtool /var/lib/ceph/tmp/ceph-${host}.mon.keyring --import-keyring /etc/ceph/ceph.client.admin.keyring


monmaptool --create --add ${host} ${ipaddr} --fsid ${fsid} /tmp/monmap --clobber


#rm -rf /var/lib/ceph/mon/ceph-${host}                                          
sudo ceph-mon --mkfs -i ${host} --monmap /tmp/monmap --keyring /var/lib/ceph/tmp/ceph-${host}.mon.keyring 

touch /var/lib/ceph/mon/ceph-${host}/done                                       
touch /var/lib/ceph/mon/ceph-${host}/upstart  
ps aux | grep "ceph-mon"    #there should be no ceph-mon                                  
ceph-mon -i ${host} 
ps aux | grep "ceph-mon"    #there we've got a ceph-mon running                           

ceph osd tree

  • In my case, manual deployment with the make, it creates and runs the mon but still the "ceph osd tree" doesn't return any output! At the end of this step, I expect to have ceph id on hard disks (the output of "lsblk" would disply that) but I don't! Any ideas? – Fatemeh khodaparast Oct 06 '20 at 14:26

You can try to touch the file sysvinit. For example, assume the host name of monitor node is node1 and the cluster name is by default, use this command touch /var/lib/ceph/mon/ceph-node1/sysvinit before starting the monitor process. This solve my problem when getting the unknown error.

The make install target of Ceph does not install the upstart script. The best option is to install packages with apt-get install ceph. If you need to run from modified sources, you can with ceph-mon -i a, assuming the monitor data already exists.
