Hi.
If I’m running:
ceph-deploy disk zap ceph001:sdaa ceph001:sda1
and
ceph-disk -v prepare /dev/sdaa /dev/sda1, get the same errors:

The separate commands (e.g. `ceph-disk -v prepare /dev/sda1`) works because then the journal is on the same device as the OSD data, so the execution is different to get them to a working state.
I suspect that there are left over partitions in /dev/sdaa that are causing this to fail, I *think* that we could pass the `-t` flag with the filesystem and prevent this.
Just to be sure, could you list all the partitions on /dev/sdaa (if /dev/sdaa is the whole device)?
Something like:
sudo parted /dev/sdaa print
Or if you prefer any other way that could tell use what are all the partitions in that device.
After
ceph-deploy disk zap ceph001:sdaa ceph001:sda1
root@ceph001:~# parted /dev/sdaa print
