But what are agents, rgws, nfss, restapis, rbdmirrors, clients and iscsi-gws? Where could I found additional information about them? Where for and how do I use them? Please, put me to the right section in the documentation.As Ceph is multi protocol storage it can talk with http/rest based object storage clients, it can act like a nfs server and iscsi target. Those groups just configure proper software stack and daemons to support it. If are sure you will go with CephFS, don't bother with them. But please notice most common deployment scenario for OpenStack on Ceph storage include RBD Block storage (included in base mon/osd) and object storage supported by RadosGW. So double check if you really don't want it.
Ok, though not needed for a minimal setup I would like to know where to find documentation and information about these services listed in the site.yml.sample. I found some of them in the Ceph documentation but not all of them.
Because it is a lot to read I would appreciate if someone could tell me if I'm looking in the right section of the documentation.
* agents - [Cache Tiering](http://docs.ceph.com/docs/master/rados/operations/cache-tiering/) * mdss - [Ceph Metadata Server Daemom](http://docs.ceph.com/docs/master/man/8/ceph-mds/) * rgws - [Rados Rest Gateway](http://docs.ceph.com/docs/master/man/8/radosgw/) * nfss - [NFS-Ganesha NFS server](http://docs.ceph.com/docs/master/cephfs/nfs/)
* restapis - ?* rbdmirrors - [RBD-Mirror](http://docs.ceph.com/docs/master/man/8/rbd-mirror/)
* clients - ? * mgrs - ?* iscsi-gw - [Ceph ISCSI Gateway](http://docs.ceph.com/docs/master/rbd/iscsi-overview/)
Thanks a lot in advance for your help. Best regards, Joerg K.
