Storage Driver: Ceph Object Storage (RADOS) This driver implements the storagedriver.StorageDriver interface and uses Ceph Object Storage as storage backend. Since RADOS is an object storage and no hierarchy notion, the following convention is used to keep the filesystem notions stored in this backend: * All the objects data are stored with opaque UUID names prefixed (e.g. "blob:d3d232ff-ab3a-4046-9ab7-930228d4c164). * All the hierarchy information are stored in rados omaps, where the omap object identifier is the virtual directory name, the keys in a specific are the relative filenames and the values the blob object identifier (or empty value for a sub directory). e.g. For the following hierarchy: /directory1 /directory1/object1 /directory1/object2 /directory1/directory2/object3 The omap "/directory1" will contains the following key / values: - "object1" "blob:d3d232ff-ab3a-4046-9ab7-930228d4c164" - "object2" "blob:db2e359d-4af0-4bfb-ba1d-d2fd029866a0" - "directory2" "" The omap "/directory1/directory2" will contains: - "object3" "blob:9ae2371c-81fc-4945-80ac-8bf7f566a5d9" * The MOVE is implemented by changing the reference to a specific blob in its parent virtual directory omap. This driver stripes rados objects to a fixed size (e.g. 4M). The idea is to keep small objects (as done by RBD on the top of RADOS) that will be easily synchronized accross OSDs. The information of the original object (i.e total size of the chunks) is stored as a Xattr in the first chunk object. Signed-off-by: Vincent Giersch <vincent.giersch@ovh.net>
