Hi All, While doing the grenade setting to test the Rocky upgrade testing [1], i found osc Rocky version (3.15 or 3.16) does not work with python-cinderclient Rocky version (>=4.0.0) [2]. Failure are due to source_replica arg has been removed from python-cinderclient which went in Rocky release and osc fix of that went in after Rocky. Openstackclient Rocky version - 3.16.0 cinderclient Rocky version - 4.0.1 These 2 version does not work because cinderclient >=4.0.0 has removed the source_replica arg which is being taken care in openstackclient > 3.16 [2] so openastackclient rocky version (3.15 or 3.16 does not work with cinderclient rocky version) We should backport the openstackclient fix [3] to Rocky and then release the osc version for Rocky. I have proposed the backport [4].
