Re: [Openstack] [nova][ceph] Libvirt Error when add ceph as nova backend

2018-10-12 Thread Eugen Block 

Hi,

the keyrings and caps seem correct to me.


yes both nodes, ceph & nova-compute node was on same network
192.168.26.xx/24 , does any special port need to allow at firewalld ?


Yes, the firewall should allow the traffic between the nodes. If this  
is just a test environment you could try disabling the firewall. If  
this is not an option, open the respective ports, an excerpt from the  
docs:


For iptables, add port 6789 for Ceph Monitors and ports 6800:7300  
for Ceph OSDs.


For more information take a look into [1]. Can you see requests  
blocked in your firewall?


Regards,
Eugen

Re: [Openstack] [nova][ceph] Libvirt Error when add ceph as nova backend

2018-10-11 Thread Eugen Block 

Hi,

your nova.conf [libvirt] section seems fine.

Can you paste the output of

ceph auth get client.nova

and does the keyring file exist in /etc/ceph/ (ceph.client.nova.keyring)?

Is the ceph network reachable by your openstack nodes?

Eugen
