FileConfig is a ConfigStore interface implementation that reads configuration

information from files.

BasePath defines the directory under which FileConfig will attempt to open and

|
read contents of various Ceph cluster configurations.
|
|
|
|
Each Ceph cluster configuration is stored under a directory named,
|
|
BasePath/ceph-cluster-<clusterid>, where <clusterid> uniquely identifies and

|
separates the each Ceph cluster configuration.
|
|
|
|
Under each Ceph cluster configuration directory, individual files named as per
|
|
the ConfigKeys constants in the ConfigStore interface, store the required

configuration information.
