Configuring rbdmap service

Automatically map and mount, or unmap and unmount, RADOS Block Devices (RBD) at boot time, or at shutdown respectively.

Prerequisites

  • Root-level access to the node doing the mounting.

  • Installation of the ceph-common package.

Procedure

  1. Open for editing the /etc/ceph/rbdmap configuration file.

  2. Add the RBD image or images to the configuration file:

    Example 

    foo/bar1    id=admin,keyring=/etc/ceph/ceph.client.admin.keyring
foo/bar2    id=admin,keyring=/etc/ceph/ceph.client.admin.keyring,options='lock_on_read,queue_depth=1024'

  3. Save changes to the configuration file.

  4. Enable the RBD mapping service:

    Example 

    [root@client ~]# systemctl enable rbdmap.service
