libceph: delay debugfs initialization until we learn global_id

2012-08-20T17:03:15Z

The debugfs directory includes the cluster fsid and our unique global_id. We need to delay the initialization of the debug entry until we have learned both the fsid and our global_id from the monitor or else the second client can't create its debugfs entry and will fail (and multiple client instances aren't properly reflected in debugfs).

rbd: introduce rados block device (rbd), based on libceph

2010-10-20T22:38:13Z

The rados block device (rbd), based on osdblk, creates a block device that is backed by objects stored in the Ceph distributed object storage cluster. Each device consists of a single metadata object and data striped over many data objects. The rbd driver supports read-only snapshots. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: factor out libceph from Ceph file system

2010-10-20T22:37:28Z

This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil
