Ceph is a distributed object, block, and file storage platform
3a86b94cb3
We need to track individual clients' ability to write to a file in order to behave rationally when a client dies or fails to reconnect after an mds restart. There is also a behavior change hiding in here: before we were adjusting max_size based on _wanted_ caps, but that was unsafe, since a client may have the old max_size value and initiate a write after informing the mds it no longer wants said caps. There will undoubtably be some fallout from that change... Also clean up instances of memset() on inode_t and friends. Define and use constructors instead. |

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
