Ceph installs various error

[Ceph_deploy] [ERROR] Runtimeerror:failed to execute Command:ceph-disk-activate–mark-init sysvinit–mount/dev/sdb1

To be honest, the question is two.
I put the OSD in a separate partition SDB executes the commands that are:
Ceph-deploy OSD Prepare NETWORK:/DEV/SDB1
Ceph-deploy OSD Activate NETWORK:/DEV/SDB1
The above is wrong.
The right thing is
Ceph-deploy Osd–zap-disk Create Network:sdb
Ceph-deploy OSD Prepare NETWORK:/DEV/SDB1:/DEV/SDB2
Ceph-deploy OSD Activate NETWORK:/DEV/SDB1:/DEV/SDB2

The problem is not resolved, into the/var/lib/ceph/tmp, delete the temporary files inside, and then try again, you can.
