问题描述

Trident找不到多路径设备：

warning msg="Multipath device not found."

level=error msg="Error encountered in multipath flush(remove) mapping command." devicePath=/dev/dm-2 error="exit status 1" logLayer=csi_frontend output="1580294.926017 | 3600a098038314f6a712b58502f334436-part14: map in use\n" requestID=5b837a90-49e4-41dd-be71-ead0c78c45a6 requestSource=CSI workflow="node_server=unstage"

虽然此设备不再位于"/dev/mapper/ "下(dm-2指向其他设备)：
