We’d like to bootstrap and deploy Ceph into alternative directory. By keeping Ceph relevant data to a separate directory mounted from a separate disk, Ceph services will start right after operating system reprovision.
While deploying with –data-dir and other directory parameters,
cephadm --data-dir /pd/var/lib/ceph --unit-dir /pd/etc/systemd/system --log-dir /pd/var/log/ceph --logrotate-dir /pd/etc/logrotate.d bootstrap --mon-ip xx.xx.xx.xx
The bootstrap failed at mon creation.
Ceph version: ceph version 18.2.4 (e7ad5345525c7aa95470c26863873b581076945d) reef (stable)

Is this a supported approach and is it a bug?
