Re: [Lustre-discuss] Where to download Lustre from since 01 Aug?
Charland, Denis
I tried to checkout Lustre 1.8.7 from the Whamcloud Git repository the same way I
did for 1.8.5 earlier this fall:
git clone -b b1_8 http://git.whamcloud.com/fs/lustre-release.git lustre
cd lustre
git checkout -b 1.8.7 1.8.7
but I get the following error message:
error: pathspec ‘1.8.7’ did not match any file(s) known to git.
What is the right version to use to checkout 1.8.7 ?

Ah, there is a v1_8_7_WC1 tag, but not a 1.8.7-wc1 tag. We are adding
the ".wc1" suffix to distinguish this from the Oracle release, which is
not identical.
Johann, could you please make a 1.8.7-wc1 tag to match the previous
practise of having both v1_8_* and 1.8.* tags for convenience.
Cheers, Andreas

Andreas,
What do you mean by "not identical"?

As in "there are some different patches in our 1.8.7-wc1 release than in Oracle's 1.8.7 release, because we made our 1.8.7-wc1 release on Oct 31, 3 months after our 1.8.6-wc1 release, but Oracle just tagged their 1.8.7 release this week".
We do monitor each others releases to keep the patch differential to a minimum.

Thanks for the info Andreas.
For the benefit of the Lustre community, could you briefly explain how the Lustre development is done at both Oracle and Whamcloud? Is the Oracle release the "Official Lustre release"?
I've been using Lustre on our clusters for about 4 years now. I began with release 1.6.3 that was developed by Cluster File Systems (aka CFS) at that time. Later Sun bought CFS then Oracle bought Sun and now there is Whamcloud involved. Not always easy to follow.
Cheers,

I cannot comment on Oracle development processes but the Whamcloud
processes are laid out on
http://wiki.whamcloud.com/display/PUB/Lustre+Development.
Many of the Whamcloud team (including Andreas and myself) have been
involved with Lustre since the CFS days.
The Whamcloud release has the backing of the Lustre community groups
(EOFS\OpenSFS) - see
http://www.whamcloud.com/news/opensfs-and-whamcloud-sign-lustre-community-tree-development-agreement/
and http://www.eofs.eu/index.php?id=6 .
If you would like to keep abreast of developments relating to Whamcloud
releases then you should sign up to the Whamcloud mailing list -

This means that you include bug fixes from Oracle into the Whamcloud release. Since they are not listed in the Changelog file, how do we know which bug fixes from Oracle have been included in the Whamcloud release?
I presume that Oracle also includes bug fixes from Whamcloud into their release. Is that correct?

If you have questions about Whamcloud Lustre releases then wc-discuss is
the appropriate place to ask them.
