You can't create a mapped device on something while it is mounted as device-mapper needs to open it exclusively.
But as seen from above, dmsetup is failing to create a flakey/delay device when /dev/sdb has a filesystem on top of it. Is there any workaround ?
Set up the file system the way you want it on sdb first. Then unmount it and create the device-mapper devices and mount that.
