Hi all: about https://bugs.launchpad.net/cinder/+bug/1452641 I submitted my solution https://review.openstack.org/#/c/289813/.
VM startup or reboot failed when volume backend of ceph mon ip address changed. And this bug also happens when vm deployed with volume backend of IPSAN, when IPSAN's iscsi ip address changed. In our product use, when we transfered our equipment to others' lab, the IP adress would changed all, including the volume backends' ip, and the pre-deployed instances would failed to start at all, which troubled us to much. I proposed to check and refresh the ip address which recored in instance's block_device_mapping tableļ¼ Matt Riedemann pointed out that it's not a good idea to perform these checks each time to call call startup or reboot APIs, and give good advice to fix this in nova-manage when this bug did happen. My question is: is it reasonable to call nova database, libvirt driver, rbd driver, cinder's api and so on in nova-manage to perferm the check and refresh connection info in BDM and fix the bug, when volume backends' ip changed. Or any other reasonable solutions? Thank you. Best regards!
