[Lustre-discuss] Lustre build and install on Ubuntu

[Dilger, Andreas]

Nathan, would you and/or Mandar be willing to incorporate the below steps into the "make debs" build target of the Lustre master branch?

While we don't maintain Debian or Ubuntu builds ourselves, it does seem like there is an increasing interest in this, and I hate seeing people having to rediscover the same problems and struggle to fix them each time. 

At one point, I also thought that there was a Lustre client in the Debian unstable repo, but is that no longer the case? I don't see that as removing the reason to getting "make debs" to work in the master branch, since there will always be people who want to try the latest code instead of waiting for the Debian/Ubuntu repo to be updated. 

Cheers, Andreas

I could install all rpms and then could also boot into my lustre-patched-kernel. I am able to mkfs.lustre my MGS (and even could mount it) But mkfs.lustre for MDT fails.
> a.       First it gave errors like “Invalid filesystem option set”. So I installed e2fsprogs-1.42.7.wc1-7.el6.x86_64.rpm and e2fsprogs-libs-1.42.7.wc1-7.el6.x86_64.rpm (which I had used for my RHEL) using “alien”
> b.      After this now it gives me another error, “Filesystem has unsupported feature(s) while setting up superblock”. I found similar issue athttps://www.mail-archive.com/pkg-lustre-maintainers@lists.alioth.debian.org/msg00263.html . I am NOT getting message “Your mke2fs.conf file does not define the ldiskfs filesystem type.”. Still tried solution suggested in the next mail, which did not work. Even links for ldiskfsprogs are not working to try. Do I need some other version of e2fsprogs?
