Hi, I came a cross a problem where if the containers are running then it affects the unmount process of the system's mount points. I am not using these mount points as shared partitions with container.
For example, I am using SD card and NAND as external storage device and mounting it to a mount point in the ramfs. Then I am launching containers and then when I try to unmount the NAND partition then my "unmount" call succeeds but I don't see the UBIFS hooks being called and because of that my UBI detach process fails. When I stopped the container then I see that kernel is calling the unmount as I see my debug prints inside the UBIFS for unmounting that partition. It seems like the calls are buffered/queued because of container. If I tried to mount my NAND partition once the container is up and try to unmount then it does unmount and detach without issue. It seems like there is an issue with namespace. I am using 4.1.8 kernel . Please let me know if you need any additional detail from my end.
