How to increase debugging level for RBD logs in OpenStack services like Glance, Cinder and Nova?

Environment

• Red Hat Open Stack Platform 5, 6. 7, 8. 9, 10.
• Red Hat Ceph Storage 1.2.3, 1.3 , 2.0.

Issue

• How to increase debugging level for RBD logs in OpenStack services like Glance, Cinder and Nova?

Resolution

• Check if the Ceph cluster is in a healthy status, using :

# ceph -s

• If the cluster is in a HEALTHY state, add the following in the [client] section in /etc/ceph/ceph.conf:

debug ms = 1
debug rbd = 20
log to file = true
log file = /var/log/[openstack service name]/ceph-$pid.log

• As an example, for the 'glance' service , add the following in /etc/ceph/ceph.conf:

debug ms = 1
debug rbd = 20
log to file = true
log file = /var/log/glance/ceph-$pid.log

• This should increase the log levels, and the logs should be present in /var/log/[openstack service name]/ceph-{PID}.log.
