python-cinderclient-functional-py39 job has been failing since 23 November, 2022[1]. The failure has been described in detail in the mailing thread replies[2][3]. In summary, a new iSCSI target path was added in the kernel, /sys/kernel/config/target/iscsi/*cpus_allowed_list*, which is causing rtslib-fb 2.7.4 to fail. This issue was fixed in rtslib-fb 2.7.5 but the upper-constraints in stable/yoga branch is 2.7.4[4]. This isn't a problem in stable/zed since the version used for rtslib-fb is 2.7.5[5]. I have proposed a requirements patch to bump the rtslib-fb version to 2.7.5[6] and tested it against cinderclient[7] where the python-cinderclient-functional-py39 job is passing. I've tried reaching out to the requirements team on IRC and on ML to make this change but there hasn't been any response. The best way to move forward and unblock our gate is to skip the failing test test_backup_create_and_delete and unblock changes in the stable/yoga branch.
