OK. compilation of Lustre 1.8.2 on Jeremy's 2.6.32.9 and stock
2.6.32.9, both failed.

Can someone tell me how I can get 2.6.30.x from Jeremy's git repository?

git branch -a works and shows me a list of various branches, but which
one should I access... don't really know... please help.

Thanks,

git tag -l
git checkout TAG

This will create a new branch based on that tag...

git checkout TAG doesn't create a branch, but will checkout all your
current files to represent the revision the tag is pointing to.

git checkout TAG -b TAG will create a "TAG" branch starting at the tap
revision.

just nitpicking,

If you check out v2.6.30 from Jeremy's git repo, you'll get THE 2.6.30 
kernel tree.  No Xen.  Jeremy added all the Xen bits in starting with 
2.6.31 (xen/master) and 2.6.32 (xen/next, xen/stable).  I think you'd have 
to merge all the xen component branches in to a fresh 2.6.30 by hand... No 
idea how bad that would be.

I think it will be easiest to get version of Lustre forward-ported 
rather than trying to backport all the Xen stuff to an older kernel.

That's assuming that what you want is a Xen-enabled Linux kernel with 
dom0 capability running Lustre.  If you just want domU support, then a 
stock kernel.org 2.6.30.x will suit your purposes.

Re: [Xen-devel] Re: Jeremy's git tags

[Dot Yet]

Yeah its for dom0. Too bad, i cant try them together.

I find no shame in admitting that I am not good at code hacking :)

In reality as a learning experience I wanted to use lustre based
storage between two nodes providing HA to some xen domU. At some point
I thought about using Sun's QFS, but since this is all on Lenny, its
not that easy, plus having a QFS client also requires custom kernel.

Thanks everyone.

Hello Dot,

Don't know if it can do exactly what your want, and since they have recoded it for version 3, there seem to be some stability problems that have to be worked out.
But Glusterfs is a clustering FS for fuse, and therefore userspace. I just use the old version (2.0.6) to share disk space in a NFS/samba way to xen domU's and it works rather well, but HA is another ballpark ofcourse.
