Hi, I wanted to understand the behaviour of using --unit-dir and --data-dir while setting up the ceph cluster using cephadm. Can I pass on a reference to a mount points on a different disk (other than the root disk) for these options? The deployment I am trying to achieve is to persist the Ceph containers systemd unit files and their persistent cluster data on a different disk than the root disk. This way, the nodes retains its identity even if the Operating System disk is redeployed on the root disk and the persistent data (systemd unit files and container data) is retained on the other disk. Is this possible with cephadm? I tried pointing unit-dir and data-dir to a different disk mount point but it failed. The unit files are always created in the /etc/systemd/system directory in the root disk.
