Hi Marcus and Kirk, Good day to you, and thank you for your email replies.
We are using Ceph RBD primary storage. I can't find any error information on agent.log, and I have set the logging to verbose (DEBUG) for all. Since I am using RBD, am I still able to run the qemu-img info command? I check the volumes table contain load of information. How do I check which record is referring to the virtual disk in question? Looking forward to your reply, thank you. Cheers.
