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.
