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

when we resend_routed_requests, the source client address is lost. This may cause problems. For example, if we resend an mds beacon (boot) to a new monitor leader, the new mdsmap will contain a new mds entry without IP address. To reproduce this bug: 1. deploy a cluster with 3 mons. 2. let active mds send beacon to mon0; standby mds send becaon to mon2 3. gdb attach to mon2 to make it unresponsive and make standby mds laggy. 4. gdb attach to mon0 to make it unresponsive and make active mds laggy. 5. detach mon2, then the standby mds will become active. 6. ceph mds dump -o - shows the active mds address is :/0 Signed-off-by: Henry C Chang <henry_c_chang@tcloudcomputing.com> Signed-off-by: Sage Weil <sage@newdream.net> |

Ceph - a scalable distributed storage system
-----------------------------------------
Please see http://ceph.newdream.net/ for current info.
----
To build the server daemons, and FUSE client,
$ ./autogen.sh
$ ./configure
$ 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:
ceph-mon -- monitor daemon. handles cluster state and configuration
information.
ceph-osd -- storage daemon. stores objects on a given block device.
ceph-mds -- metadata daemon. handles file system namespace.
ceph-fuse -- fuse client.
tools:
ceph -- send management commands to the monitor cluster.
rados -- interact with the object store
rbd -- manipulate rados block device images
monmaptool -- create/edit mon map
osdmaptool -- create/edit osd map
crushtool -- create/edit crush map
scripts:
mkcephfs -- cluster mkfs tool
init-ceph -- init.d start/stop script
