[lustre-discuss] Compiling from sources with Debian 8

[Patrick Farrell]

I suspect it might be a string format change that's affecting a step in the build process you gave.

At first glance, I'd say manually verify the output of this step from compile.sh:
# Extract lustre version, replace "_" by "." and remove leading letter "v".
LUSTRE_VERSION=$(echo `git describe` | sed -e "s/_/\./g" | cut -c2-)

It's possible the info provided by git describe changed slightly and the sed and cut commands don't match up any more.  You could fix them or set it manually.

Good luck,
Patrick Farrell

Subject: [lustre-discuss] Compiling from sources with Debian 8

Hi there,

We run lustre 2.6/2.7 on our Centos 6.6 (servers) and 7 (clients) cluster. We have a few webservers running Debian that need to access the storage. I followed the procedure given by Thomas Stibor about Ubuntu 14 last year.

I could successfully compile the binaries and modules after some digging. He also left an already compiled lustre 2.7.63 and modules for kernel 3.16.0-4 online.

If I install his binaries, it works well. If I install the one generated by the procedure, the modules don't load and a weird thing happen. Running dmesg warns me about one surprising thing :

I pulled the master git branch, and coul obtain
linux-patch-lustre_2.7.63.0-16-g8524994_all.deb  lustre-client-modules-3.16.7-ckt11-lustre-my-build_2.7.63.0-16-g8524994_amd64.deb  lustre-tests_2.7.63.0-16-g8524994_amd64.deb

I just don't get it. Why the shown version of the module is 2.3 ?
I tried to compile from the 2.7 branch but the 2.7.0 version doesn't compile with kernel 3.16, as suggested in LU-7042

I probably miss something. Sorry I'm not familiar with compilers (usually the ./configure && make && make install works or warns you about missing dependencies and i don't go farther).

Thank you

Jerome

PS : Here is the procedure followed to compile


apt-get install linux-headers-3.16.0-4-amd64 libtool automake linux-source-3.16
git clone git://git.whamcloud.com/fs/lustre-release.git
cd /usr/src/
tar xf linux-source-3.16.tar.xz
cd /home/build/lustre-release/
vi debian/rules (edit so it doesn't stop with autogen because it doesn't find the kernel sources)
(modify --with-linux= option with current path --with-linux=/usr/src/linux-3.16 in kdist_config section)
aptitude install module-assistant libreadline-dev debhelper  dpatch libsnmp-dev quilt devscripts
 vi debian/control
(modify the dependency for unsatisfied linux-headers called linux-headers-something in jessie)
vi compile.sh
#!/bin/bash
unset DEBEMAIL
unset EMAIL
unset DEBFULLNAME
unset NAME

export DEBFULLNAME="Niemand Nobody"
export EMAIL="npcomplete at example.com"

# Extract lustre version, replace "_" by "." and remove leading letter "v".
LUSTRE_VERSION=$(echo `git describe` | sed -e "s/_/\./g" | cut -c2-)

# Add entry into debian/changelog such that packages have proper version names.
dch --newversion $LUSTRE_VERSION --distribution unstable --nomultimaint -t "Build from official master upstream."

#
sh ./autogen.sh

# Build debian packages.
dpkg-buildpackage

# Build modules.
#export MODULE_LOC=${PWD}
#cd /usr/src/linux
#make-kpkg modules_image --append-to-version -lustre-my-build --revision `date +"%Y%m%d"`

Then i got stuck on "checking for external module build target" for a while, fixed by running "make scripts" in the kernel source folder
It finally compiled !
