I check the system service that all is normal ,I don't know why I create disk faied by gwcli。

Start by reproducing the `/disks> create pool=rbd image=disk_1 size=1G` operation with the stated CentOS 7.9, kernel 5.19, Ceph, and VM environment. Trace the failure from `tcmu-runner`'s `add_device` through LIO and the journal messages; done means identifying the cause of the missing `uio0` device and documenting or fixing disk creation.
