Hi All, Please, I' d like to know if cinder backup and/or cinder snapshot call qemu guest agent for fsfreezing. If Yes, does it freeze file systems in the volume? Regards Ignazio
Unfortunately no, initiating a snapshot or backup from Cinder does not call out to Nova to do any guest quiescing. There would need to be something else coordinating the calls between the guest OS and initiating the Cinder snapshot to do that. Sean
