* : Tag zfs-0.4.0
|
||||
|
||||
* : ZFS project migrated from Subversion which leveraged a
|
||||
quilt based patch stack to Git and a TopGit managed patch
|
||||
stack. The new method treats all patches as Git branches
|
||||
which can be more easily shared for distributed development.
|
||||
Consult the top level GIT file for detailed information on
|
||||
how to properly develop for this package using Git+TopGit.

|
||||
* : Tag zfs-0.3.3
|
||||
|
||||
* : Minor script updates and tweaks to be compatible with
|
||||
the latest version of the SPL.
|
||||
|
||||
2008-06-13 Brian Behlendorf <behlendorf1@llnl.gov>
|
||||
|
||||
* vdev_disk.diff: Replace vdev_disk implementation which was
|
||||
based on the kmalloc'ed logical address space with a version
|
||||
which works with vmalloc'ed memory in the virtual address space.
|
||||
This was done to support the new SPL slab implementation which
|
||||
is based on virtual addresses to avoid the need for contigeously
|
||||
allocated memory.
|
||||
|
||||
2008-06-05 Brian Behlendorf <behlendorf1@llnl.gov>
|
||||
|
||||
* arc-vm-integration.diff: Reduce maximum default arc memory
|
||||
usage to 1/4 of total system memory. Because all the bulk data
|
||||
is still allocated on the slab memory fragmentation is a serious
|
||||
concern. To address this in the short term we simply need to
|
||||
leave lots of free memory.
|
||||
|
||||
* fix-stack.diff: First step towards reducing stack usage so
|
||||
we can run the full ZFS stack using a stock kernel.
|
||||
|
||||
2008-06-04 Brian Behlendorf <behlendorf1@llnl.gov>
|
||||
|
||||
* : Tag zfs-0.3.2
|
||||
|
||||
* : Extensive improvements to the build system to detect kernel
|
||||
API changes so we can flexibly build with a wider range of kernel
|
||||
versions. The code has now been testing with the 2.6.18-32chaos
|
||||
and 2.6.25.3-18.fc9 kernels, however we should also be compatible
|
||||
with other kernels in the range of 2.6.18-2.6.25. The only
|
||||
remaining issue preventing us from running with a stock
|
||||
kernel is ZFS stack usage.
|
||||
|
||||
2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>

||||
* : License headers including URCL added for release.
|

* configure.ac: Improved autotools support and configurable debug.
|

|
||||
2008-05-15 Brian Behlendorf <behlendorf1@llnl.gov>
|
||||
|
||||
* : Updating original ZFS sources to build 89 which
|
||||
includes the new write throttling changes plus support
|
||||
for using ZFS as your root device. Neither of which
|
||||
will work exactly right without some more work but this
|
||||
gets us much closers to the latest source.

=========================== WHY USE GIT+TOPGIT? ==========================
|
||||
|
||||
Three major concerns were on our mind when setting up this project.
|
||||
|
||||
o First we needed to structure the project in such a way that it would be
|
||||
easy to rebase all of our changes on the latest official ZFS release
|
||||
from Sun. We absolutely need to be able to benefit from the upstream
|
||||
improvements and not get locked in to an old version of the code base.
|
||||
|
||||
o Secondly, we wanted to be able to easily manage our changes in terms
|
||||
of a patch stack or graph. This allows us to easily isolate specific
|
||||
changes and push them upstream for inclusion. It also allows us to
|
||||
easily update or drop specific changes based on what occurs upstream.
|
||||
|
||||
o Thirdly we needed our DVCS to be integrated with the management of this
|
||||
patch stack or graph. We have tried other methods in the past such as
|
||||
SVN+Quilt but have found managing the patch stack becomes cumbersome.
|
||||
By using Git+TopGit to more tightly integrate our patches in to the repo
|
||||
we expect several benefits. One of the most important will be the
|
||||
ability to easily work on the patch's with a distributed development
|
||||
team, additionally the repo can track patch history, and we can utilize
|
||||
Git to merge patches and resolve conflicts.
|
||||
|
||||
TopGit is designed to specifically address these concerns by providing
|
||||
tools to simplify the handling of large numbers of interdependent topic
|
||||
branches. When using a TopGit aware repo every topic branch represents
|
||||
a 'patch' and that branch references its dependent branches. The union
|
||||
of all these branches is your final source base.
|
||||
|
||||
========================= SETTING UP GIT+TOPGIT ==========================
|
||||
|
||||
First off you need to install a Git package on your system. For my
|
||||
purposes I have been working on a RHEL5 system with git version 1.5.4.5
|
||||
installed and it has been working well. You will also need to go get
|
||||
the latest version of TopGit which likely is not packaged nicely so you
|
||||
will need to build it from source. You can use Git to clone TopGit
|
||||
from the official site here and your all set:
|
||||
|
||||
> git clone git://repo.or.cz/w/topgit.git
|
||||
> make
|
||||
> make install # Default installs to $(HOME)
|
||||
|
||||
========================== TOPGIT AND ZFS ================================
|
||||
|
||||
One you have Git and TopGit installed you will want to clone a copy of
|
||||
the Linux ZFS repo. While this project does not yet have a public home
|
||||
it hopefully will some day. In the meanwhile if you have VPN access to
|
||||
LLNL you can clone the latest official repo here. Cloning a TopGit
|
||||
controlled repo is very similar to cloning a normal Git repo, but you
|
||||
need to remember to use 'tg remote' to populate all topic branches.
|
||||
|
||||
> git clone http://eris.llnl.gov/git/zfs.git zfs
|
||||
> cd zfs
|
||||
> tg remote --populate origin
|
||||
|
||||
Now that you have the Linux ZFS repo the first thing you will probably
|
||||
want to do is have a look at all the topic branches. TopGit provides
|
||||
a summary command which shows all the branches and a brief summary for
|
||||
each branch obtained from the .topmsg files.
|
||||
|
||||
> tg summary
|
||||
0 feature-branch [PATCH] feature-branch
|
||||
feature-commit-cb [PATCH] feature commit cb
|
||||
feature-zap-cursor-to-key [PATCH] feature zap cursor to key
|
||||
...
|
||||
|
||||
By convention all TopGit branches are usually prefixed with 't/', however
|
||||
I have chosen not to do this for simplicity. A different convention I have
|
||||
adopted is to tag the top most TopGit branch as 'top' for easy reference.
|
||||
This provides a consistent label to be used when you need to reference the
|
||||
branch which contains the union of all topic branches.
|
||||
|
||||
One thing you may also notice about the 'tg summary' command is it does
|
||||
not show the branches in dependent order. This is done because TopGit allows
|
||||
each branch to express multiple dependencies as a DAC. Initially this seemed
|
||||
like an added complication which I planned to avoid by just implementing a
|
||||
stack using the graph. However, this ended up being problematic because
|
||||
with a stack when a change was made to a branch near the base, it was a
|
||||
very expensive operation to merge the change up to the top of the stack.
|
||||
By defining the dependencies as a graph it is possible to keep the depth
|
||||
much shallower thus minimizing the merging. It has also proved insightful
|
||||
as to each patches actual dependencies.
|
||||
|
||||
To see the dependencies you will need to use the --graphviz option and pipe
|
||||
the result to dot for display. The following command works fairly well for
|
||||
me. Longer term it would be nice to update this option to use a preferred
|
||||
config options stored in the repo.
|
||||
|
||||
> tg summary --graphviz | dot -Txlib -Nfontsize=8
|
||||
|
||||
========================= UPDATING A TOPIC BRANCH ========================
|
||||
|
||||
Updating a topic branch in TopGit is a pretty straight forward but there
|
||||
are a few rules you need to be aware of. The basic process involves
|
||||
checking out the relevant topic branch where the changes need to be made,
|
||||
making the changes, committing the changes to the branch and then merging
|
||||
those changes in to dependent branches. TopGit provides some tools to make
|
||||
this pretty easy, although it may be a little sluggish depending on how many
|
||||
dependent branches are impacted by the change. Here is an example:
|
||||
|
||||
> git checkout modify-topic-branch # Checkout the proper branch
|
||||
> ...update branch... # Update the branch
|
||||
> git commit -a # Commit your changes
|
||||
> git checkout top # Checkout the top branch
|
||||
> tg update # Recursively merge in new branch
|
||||
|
||||
Assuming you change does not introduce any conflicts your done. All branches
|
||||
were dependent on your change will have had the changed merged in. If your
|
||||
change introduced a conflict you will need to resolve the conflict and then
|
||||
continue on with the update.
|
||||
|
||||
========================== ADDING A TOPIC BRANCH =========================
|
||||
|
||||
Adding a topic branch in TopGit can be pretty straight forward. If your
|
||||
adding a non-conflicting patch in parallel with other patches of the same
|
||||
type, then things are pretty easy and TopGit does all the work.
|
||||
|
||||
> git co existing-topic-branch # Checkout the branch to add after
|
||||
> tg create new-topic-branch # Create a new topic branch
|
||||
> ...update .topmsg... # Update the branch message
|
||||
> ...create patch... # Update with your changes
|
||||
> git commit -a # Commit your changes
|
||||
> git co dependent-topic-branch # Checkout dependent branch
|
||||
> tg depend add new-topic-branch # Update dependencies
|
||||
> git checkout top # Checkout the top branch
|
||||
> tg update # Recursively merge in new branch
|
||||
|
||||
If you need to add your patch in series with another change things are
|
||||
a little more complicated. In this case TopGit does not yet support removing
|
||||
dependencies so you will need to do it by hand, as follows.
|
||||
|
||||
> git co existing-topic-branch # Checkout the branch to add after
|
||||
> tg create new-topic-branch # Create a new topic branch
|
||||
> ...update .topmsg... # Update the branch message
|
||||
> ...create patch... # Update with your changes
|
||||
> git commit -a # Commit your changes
|
||||
> git co dependent-topic-branch # Checkout dependent branch
|
||||
> ...update .topdeps... # Manually update dependencies
|
||||
> git commit -a # Commit your changes
|
||||
> tg update # TopGit update
|
||||
> git checkout top # Checkout the top branch
|
||||
> tg update # Recursively merge in new branch
|
||||
|
||||
Once your done, I find it is a good idea view the repo using the
|
||||
'tg summary --graphviz' command and verify the updated dependency graph.
|
||||
|
||||
========================= REMOVING A TOPIC BRANCH ========================
|
||||
|
||||
Removing a topic branch in TopGit is also currently not very easy. To remove
|
||||
a dependent branch the basic process is to commit a patch which reverts all
|
||||
changes on the branch. Then that reversion must be merged in to all dependent
|
||||
branches, the dependencies manually updated and finally the branch removed.
|
||||
If the branch is not empty you will not be able to remove it.
|
||||
|
||||
> git co delete-topic-branch # Checkout the branch to delete
|
||||
> tg patch | patch -R -p1 # Revert all branch changes
|
||||
> git commit -a # Commit your changes
|
||||
> git checkout top # Checkout the top branch
|
||||
> tg update # Recursively merge revert
|
||||
> git co dependent-topic-branch # Checkout dependent branch
|
||||
> ...update .topdeps... # Manually update dependencies
|
||||
> git commit -a # Commit your changes
|
||||
> tg delete delete-topic-branch # Delete empty topic branch
|
||||
|
||||
Once your done, I find it is a good idea view the repo using the
|
||||
'tg summary --graphviz' command and verify the updated dependency graph.
|
||||
|
||||
============================ TOPGIT TODO =================================
|
||||
|
||||
TopGit is still a young package which seems to be under active development
|
||||
by its author. It provides the minimum set of commands needed but there
|
||||
are clearly areas which simply have not yet been implemented. My short
|
||||
list of features includes:
|
||||
|
||||
o 'tg summary --deps', option to display a text version of the topic
|
||||
branch dependency DAC.
|
||||
|
||||
o 'tg depend list', list all topic branch dependencies.
|
||||
|
||||
o 'tg depend delete', cleanly remove a topic branch dependency.
|
||||
|
||||
o 'tg create', cleanly insert a topic branch in the middle
|
||||
of the graph and properly take care updating all dependencies.
|
||||
|
||||
o 'tg delete', cleanly delete a topic branch in the middle
|
||||
of the graph and properly take care updating all dependencies.

============================ ZFS KERNEL BUILD ============================
|
||||
|
||||
1) Build the SPL (Solaris Porting Layer) module which is designed to
|
||||
provide many Solaris APIs in the Linux kernel which are needed
|
||||
by ZFS. To build the SPL:
|
||||
|
||||
tar -xzf spl-x.y.z.tgz
|
||||
cd spl-x.y.z
|
||||
./configure --with-linux=<kernel src>
|
||||
make
|
||||
make check <as root>
|
||||
|
||||
2) Build ZFS, this port is based on build 89 of ZFS from OpenSolaris.
|
||||
You will need to have both the kernel and SPL source available.
|
||||
To build ZFS for use as a Linux kernel module (default):
|
||||
|
||||
tar -xzf zfs-x.y.z.tgz
|
||||
cd zfs-x.y.z
|
||||
./configure --with-linux=<kernel src> \
|
||||
--with-spl=<spl src>
|
||||
make
|
||||
make check <as root>
|
||||
|
||||
========================= ZFS USER LIBRARY BUILD =========================
|
||||
|
||||
1) Build ZFS, this port is based on build 89 of ZFS from OpenSolaris.
|
||||
To build ZFS as a userspace library:
|
||||
|
||||
tar -xzf zfs-x.y.z.tgz
|
||||
cd zfs-x.y.z
|
||||
./configure --zfsconfig=user
|
||||
make
|
||||
make check <as root>
|
||||
|
||||
============================ ZFS LUSTRE BUILD ============================
|
||||
|
||||
1) Build the SPL (Solaris Porting Layer) module which is designed to
|
||||
provide many Solaris APIs in the Linux kernel which are needed
|
||||
by ZFS. To build the SPL:
|
||||
|
||||
tar -xzf spl-x.y.z.tgz
|
||||
cd spl-x.y.z
|
||||
./configure --with-linux=<kernel src>
|
||||
make
|
||||
make check <as root>
|
||||
|
||||
2) Build ZFS, this port is based on build 89 of ZFS from OpenSolaris.
|
||||
To build ZFS as a userspace library for use by a Lustre filesystem:
|
||||
|
||||
tar -xzf zfs-x.y.z.tgz
|
||||
cd zfs-x.y.z
|
||||
./configure --zfsconfig=lustre \
|
||||
--with-linux=<kernel src> \
|
||||
--with-spl=<spl src>
|
||||
make
|
||||
make check <as root>
|
||||
|
||||
3) Provided is an in-kernel test application called kpios which can be
|
||||
used to simulate a Lustre IO load. It may be used as a stress test
|
||||
or as a performance to measure your configuration. To simplify testing
|
||||
there are scripts provided in the scripts/ directory. A single test
|
||||
can be run as follows:
|
||||
|
||||
WARNING: You MUST update DEVICES in the create-zpool.sh script
|
||||
to reference the devices you wish to use.
|
||||
|
||||
cd scripts
|
||||
./load-zfs.sh # Load the ZFS/SPL module stack
|
||||
./create-zpool.sh # Modify DEVICES to list your zpool devices
|
||||
./zpios.sh # Modify for your particular kpios test
|
||||
./unload-zfs.sh # Unload the ZFS/SPL module stack
|
||||
|
||||
Enjoy,
