failed to launch instance. ceph issue [closed]
what I did: upgraded all servers (ubuntu 14.04 LTS), and rebooted them.
I am getting "failed to launch instance. no valid host was found".
I found this in the nova-scheduler.log http://paste.openstack.org/show/159949/
So it seems it is having problem connecting to the ceph cluster. Any pointers on what I can try?
Thanks!
Confirm on your compute node that /etc/ceph/ceph.conf exists, contains the correct information about your ceph cluster and has the right authx information so that the compute node which is a client of Ceph can connect to the cluster outside of OpenStack/Nova.
