Ceph is a distributed object, block, and file storage platform

If the client reasserts caps from replayed requests, the inodes don't yet exists during the reconnect (or even rejoin) stage. So, if we don't find the inode, keep the reconnect info around. When processing a replayed request in CInode::encode_inodestat, set wanted/issued appropriately. This is incomplete. We really need something to ensure we deal with replayed requests before new requests are handled.. and on a cluster-wide basis, since requests may involve slave requests to other mds's. We also should clean up reconnects unclaimed after all replays are complete. And somehow inform the client when the cap is officially nonexistent and EBADF. |

Ceph - a scalable distributed file system
-----------------------------------------
Please see http://ceph.newdream.net/ for current info.
----
To build the Linux kernel client,
$ cd src/kernel
$ make
or
$ make KERNELDIR=/path/to/linux
$ insmod ceph.ko
$ mount -t ceph 1.2.3.4:/ /mnt/ceph
...
----
To build the server daemons, and FUSE client,
$ ./autogen.sh
$ ./configure
$ cd src
$ make
(Note that the FUSE client will only be built if libfuse is present.)
----
A quick summary of binaries that will be built in src/
daemons:
cmon -- monitor daemon. handles cluster state and configuration
information.
cosd -- storage daemon. stores objects on a given block device.
cmds -- metadata daemon. handles file system namespace.
cmonctl -- send commands to the monitor cluster.
userland clients:
cfuse -- fuse client.
csyn -- synthetic workload generator client.
tools:
mkmonfs -- create a fresh monfs (for a new filesystem)
monmaptool -- create/edit mon map
osdmaptool -- create/edit osd map
crushtool -- create/edit crush map
dupstore -- duplicate an osd object store (offline)
development/debugging:
fakesyn -- simulator with synthetic workload
fakefuse -- simulator that mounts with fuse
