ruffian_sheepwhoami-rajat:I want to implement the remaining four unimplemented features. For snapshot mount and snapshot rollback, what configuration do I need to change to increase the test case?

ruffian_sheepwhoami-rajat:In the use case I executed before, I didn't find the test cases related to these two functions, so I was wondering if I didn't open any features and the test cases were missing.07:49

geguileoKeithMnemonic1: what OpenStack release where they using on the system that has problems to live migrate?18:00
*** mmethot has quit IRC18:00
geguileoKeithMnemonic1: I don't think it's related, but maybe it has to do with https://review.opendev.org/#/c/551302/18:01
KeithMnemonic1pike18:01
*** e0ne has joined #openstack-cinder18:01
KeithMnemonic1geguileo so that could apply for sure18:02
KeithMnemonic1but that does not explain the "lun changed" message that occurs when the migration has not even be in process18:03
geguileoKeithMnemonic1: And by the way, the fact that you see a SCSI message in the system logs saying that LUNs have changed also happens when you remove a LUN normally18:03
geguileoKeithMnemonic1: When using shared targets any mapping changes on the backend will be reported to the iSCSI initiator on the host18:04
KeithMnemonic1ok so then those might not be correlated18:04
geguileoKeithMnemonic1: So if Nova calls cinder to initialize the connection of another volume, when Cinder does the operation, you'll see it18:04
KeithMnemonic1but still somewhere it gets the wrong lun and maybe that is from BDM not being accurate18:04
geguileoKeithMnemonic1: And when the detach in Nova calls terminate_connection in Cinder, you'll also see it when Cinder unmaps the volume18:04
KeithMnemonic1BTW your blogs on this were really good18:05
geguileoKeithMnemonic1: glad you liked it :-)18:05
