Hi, I have read through some documents about authentication and user management about ceph, everything works fine with me, I can create a user and play with the keys and caps of that user. But I cannot find where those keys or capabilities stored, obviously, I can export those info to a file but where are they if I don't export them out? Looks like these information (keys and caps) of the user is stored in memory? but I still can list them out after rebooting my machine. Or these info are persisted in some type of DB I didn't aware? Can anyone help me out?
Authentication keys and caps are kept by the monitor in its store, either a leveldb or a rocksdb, in its data directory.
The monitor's data directory are, by default, in /var/lib/ceph/mon/ceph-X, with X being the monitor's id. The store is within that directory, named `store.db`.
The store in not in human-readable format, but you can use ceph-kvstore-tool to walk the keys if you want. Please note that, should you want to do this, the monitor must be shutdown first.
