Andrew, We have some of that at metrics.ceph.com (and are planning to add a release-specific aspect to it). What parts of stackalytics do you think are the best things to include? Right now I'm thinking of the following for each tagged major release: * new committers * total committers during this release cycle * lines of code added * commits * list messages during the release cycle * irc messages during release cycle * Activity per repository this release cycle (perhaps we can help break out by module: rgw/rbd/mds/rados/core?) Anything I'm missing?

More importantly, authors can update this information with the same path they use on a daily basis to contribute to ceph itself: there is nothing to learn to fix a mistake or add a new affiliation. The command line is also a convenient way to see that the mapping works, without the need to deploy a graphical user interface. And to answer Patrick's question : what I would like to see is a count of reviewers in a graphical user interface. It is important to me ( and probably others ) when I explain to my employer the nature of the work I do in Ceph. If reviews show on a leaderboard, it is easier to explain why it is important to keep the project healthy because other developers also spend time reviewing.

[PATCH v2 0/2] Add ceph root filesystem functionality and documentation.
From: Mark Doffman mark.doff...@codethink.co.uk
Hi All,
The following is a second version of a patch series that adds the ability to use
a ceph distributed file system as the root device.
Changes from version 1
fs/ceph/root.c:
The parsing code that takes the DHCP option 17 and kernel command line
parameters has been extensively altered.
The parsing now accepts multiple monitor addresses and ipv6 addresses.
The monitors listed in DHCP option 17 are now concatenated with those
listed on the kernel command line.
The patch series applies to v3.13-rc8-7-g3539717
Thanks
Mark

+Mounting the root filesystem via Ceph (cephroot)
+===
+
+Written 2013 by Rob Taylor rob.tay...@codethink.co.uk
+
+derived from nfsroot.txt:
+
+Written 1996 by Gero Kuhlmann g...@gkminix.han.de
+Updated 1997 by Martin Mares m...@atrey.karlin.mff.cuni.cz
+Updated 2006 by Nico Schottelius nico-kernel-nfsr...@schottelius.org
+Updated 2006 by Horms ho...@verge.net.au
+
+
+
+In order to use a diskless system, such as an X-terminal or printer server
+for example, it is necessary for the root filesystem to be present on a
+non-disk device. This may be an initramfs (see Documentation/filesystems/
+ramfs-rootfs-initramfs.txt), a ramdisk (see Documentation/initrd.txt), a
+filesystem mounted via NFS or a filesystem mounted via Ceph. The following
+text describes on how to use Ceph for the root filesystem.
+
+For the rest of this text 'client' means the diskless system, and 'server'
+means the Ceph server.
+
+
+1.) Enabling cephroot capabilities
+-
+
+In order to use cephroot, CEPH_FS needs to be selected as
+built-in during configuration. Once this has been selected, the cephroot
+option will become available, which should also be selected.
+
+In the networking options, kernel level autoconfiguration can be selected,
+along with the types of autoconfiguration to support. Selecting all of
+DHCP, BOOTP and RARP is safe.
+
+
+2.) Kernel command line
+---
+
+When the kernel has been loaded by a boot loader (see below) it needs to be
+told what root fs device to use. And in the case of cephroot, where to find
+both the server and the name of the directory on the server to mount as root.
+This can be established using the following kernel command line parameters:
+
+root=/dev/ceph
+
+This is necessary to enable the pseudo-Ceph-device. Note that it's not a
+real device but just a synonym to tell the kernel to use Ceph instead of
+a real device.
+
+cephroot=monaddr:/[subdir],ceph-opts
+
+ monaddr Monitor address. Each takes the form host[:port]. If the port
+ is not specified, the Ceph default of 6789 is assumed.
+
+ subdir A subdirectory subdir may be specified if a subset of the file
+ system is to be mounted
+
+ ceph-optsStandard Ceph options. All options are separated by commas.
+ See Documentation/filesystems/ceph/ceph.txt for options and
+ their defaults.
Maybe there is an existing convention here, but: it seems like it would be
simpler to do something like
cephroot=ip[:port][,...]:/[subdir]
i.e., the existing syntax used by mount, that (among other things) can
also include a port, or be a list of mon ips, so that the parsing code
can be re-used. Then,
cephopts=ceph-opts
Hopefully this would avoid the parsing in root.c and make things behave
more consistently with respect to how mount(8) is used?
This would make things more consistent with mount, and easier! The
reason to keep it the way it is is for consistency with NFS and DHCP
option 17.
NFS concatenates the options in DHCP root-path (option 17) with the ones
placed on the kernel command line. We could separate out the device and
path strings from the options, but they would still be merged together
in the DHCP string. Some parsing would still be required to split the
DHCP string and merge with command line options. I'd prefer to keep them
together on the command line also, just to have things stay similar to NFS.
Thanks

[PATCH v2 1/2] init: Add a new root device option, the Ceph file system
From: Mark Doffman mark.doff...@codethink.co.uk
Analogous to NFS add a new root device option, the ability
to boot using the Ceph networked file system as the root fs.
This patch adds a new root device option '/dev/ceph' that
uses a ceph networked file system. File system parameters
are passed using a new kernel parameter: 'cephroot'.
The 'cephroot' parameters are very similar to 'nfsroot'.

+Mounting the root filesystem via Ceph (cephroot)
+===
+
+Written 2013 by Rob Taylor rob.tay...@codethink.co.uk
+
+derived from nfsroot.txt:
+
+Written 1996 by Gero Kuhlmann g...@gkminix.han.de
+Updated 1997 by Martin Mares m...@atrey.karlin.mff.cuni.cz

+
+
+
+In order to use a diskless system, such as an X-terminal or printer server
+for example, it is necessary for the root filesystem to be present on a
+non-disk device. This may be an initramfs (see Documentation/filesystems/
+ramfs-rootfs-initramfs.txt), a ramdisk (see Documentation/initrd.txt), a
+filesystem mounted via NFS or a filesystem mounted via Ceph. The following
+text describes on how to use Ceph for the root filesystem.
+
+For the rest of this text 'client' means the diskless system, and 'server'
+means the Ceph server.
+
+
+1.) Enabling cephroot capabilities
+-
+
+In order to use cephroot, CEPH_FS needs to be selected as
+built-in during configuration. Once this has been selected, the cephroot
+option will become available, which should also be selected.
+
+In the networking options, kernel level autoconfiguration can be selected,
+along with the types of autoconfiguration to support. Selecting all of
+DHCP, BOOTP and RARP is safe.
+
+
+2.) Kernel command line
+---
+
+When the kernel has been loaded by a boot loader (see below) it needs to be
+told what root fs device to use. And in the case of cephroot, where to find
+both the server and the name of the directory on the server to mount as root.
+This can be established using the following kernel command line parameters:
+
+root=/dev/ceph
+
+This is necessary to enable the pseudo-Ceph-device. Note that it's not a
+real device but just a synonym to tell the kernel to use Ceph instead of
+a real device.
+
+If cephroot is not specified, it is expected that that a valid mount will be
+found via DHCP option 17, Root Path [1]
+
+cephroot=monaddrs:/[subdir],ceph-opts
+
+ monaddrsMonitor addresses separated by commas. Each takes the form
+ host[:port]. If the port is not specified, the Ceph default
+ of 6789 is assumed.
+
+ subdir A subdirectory subdir may be specified if a subset of the file
+ system is to be mounted
+
+ ceph-opts Standard Ceph options. All options are separated by commas.
+ See Documentation/filesystems/ceph/ceph.txt for options and
+ their defaults.

+ cephroot was derived from nfsroot by Rob Taylor rob.tay...@codethink.co.uk

+ The nfsroot code in the kernel and the RARP support have been written

v0.75 contributors credits ( experimental) (take 2)
[Amended after comments from Noah Watkins, Patrick McGarry, Andrew Woodward, Ian Colle, Robin H. Johnson] Hi Ceph, Here is a sorted list of authors and organizations who contributed to v0.75, by number of commits or reviews back to v0.74. The affiliation of authors to organizations can be updated by submitting a patch to https://github.com/ceph/ceph/blob/master/.organizationmap All commits are reviewed but the number of reviews is a fraction of the number of commits. The reviewer(s) is only mentioned in the message of the merge although it means that all associated commits have been reviewed.
