ceph-immutable-object-cache – Ceph daemon for immutable object cache

Synopsis

ceph-immutable-object-cache

Description

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 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.

Options

-c ceph.conf, --conf=ceph.conf

Use ceph.conf configuration file instead of the default /etc/ceph/ceph.conf to determine monitor addresses during startup.

-m monaddress[:port]

Connect to specified monitor (instead of looking through ceph.conf).

-i ID, --id ID

Set the ID portion of name for ceph-immutable-object-cache

-n TYPE.ID, --name TYPE.ID

Set the rados user name for the gateway (eg. client.ceph-immutable-object-cache)

--cluster NAME

Set the cluster name (default: ceph)

-d

Run in foreground, log to stderr

-f

Run in foreground, log to usual location

Availability

ceph-immutable-object-cache is part of Ceph, a massively scalable, open-source, distributed storage system. Please refer to the Ceph documentation at http://ceph.com/docs for more information.
