Description
|
|
|
|
|
===========
|
|
|
|
|
|
|
|
|
|
:program:`ceph-immutable-object-cache` is a daemon for object cache of RADOS
|
|
|
|
|
objects among Ceph clusters. It will promote the objects to a local directory
|
|
|
|
|
upon promote requests and future reads will be serviced from these cached
|
|
|
|
|
objects.

|
|
|
It connects to local clusters via the RADOS protocol, relying on
|
2018-12-29 08:50:44 +00:00
|
|
|
default search paths to find ceph.conf files, monitor addresses and
|
|
|
|
|
authentication information for them, i.e. ``/etc/ceph/$cluster.conf``,
|
|
|
|
|
``/etc/ceph/$cluster.keyring``, and
|
|
|
|
|
``/etc/ceph/$cluster.$name.keyring``, where ``$cluster`` is the
|
|
|
|
|
human-friendly name of the cluster, and ``$name`` is the rados user to
|
|
|
|
|
connect as, e.g. ``client.ceph-immutable-object-cache``.
