Lab 11.1 --Ceph- cannot deploy OSD

In step "ceph-deploy osd create --data /dev/xvdb storage1"
Got the error
[storage1][INFO ] Running command: sudo /usr/sbin/ceph-volume --cluster ceph lvm create --bluestore --data /dev/xvdb

I did not find /dev/xvdb in any of the nodes. So I tried with /dev/vdb which is available
In this case I got the errors

and no OSD was created
I ran the ceph-volume command separately to test it and saw this output
