Mutually exclusive conditions on deployment with dmcrypt dedicated journal

[9seconds]

I've been trying to deploy ceph cluster with dedicated dmcrypted journals and met following:

To prepare OSDs with dmcrypt, i need to set both raw_multi_journal and dmcrypt_dedicated_journal to true:
https://github.com/ceph/ceph-ansible/blob/master/roles/ceph-osd/tasks/scenarios/dmcrypt-dedicated-journal.yml#L25-L27

But at the same time, this is invalid settings here: https://github.com/ceph/ceph-ansible/blob/master/roles/ceph-common/tasks/checks/check_mandatory_vars.yml#L96

I've tried to remove mutually exclusive or (dmcrypt_dedicated_journal and raw_multi_journal) and deployment is OK, but I am not quite sure if it won't break anything else.

Thanks for the report. I think the fix here is to remove this line: https://github.com/ceph/ceph-ansible/blob/master/roles/ceph-osd/tasks/scenarios/dmcrypt-dedicated-journal.yml#L25

The check in check_mandatory_vars is correct because you really can't use dmcrypt_dedicated_journal and raw_multi_journal at the same time.
