[lustre-discuss] (SOLVED) Unable to compile client in Debian

[Alejandro Sierra]

Hello:

In July I was able to solve this problem, following these steps:

1. Use the previous stable version, stretch, which has the kernel 4.9
and gcc  6.3.
2. Install the package development and module packages, including
debhelper, module-assistant and linux-headers-4.9.0-9-amd64
linux-source-4.9
3. Get the Lustre source code closer to the one the server is using
(on CentOS7), in my case lustre-2.10.8.
4. Compile the kernel
5. Compile lustre for client
    tar xf /usr/src/lustre.tar.bz2
   cd modules/lustre/
   fakeroot make debs
   fakeroot debian/rules binary-modules
6. Install the new created packages:
    sudo dpkg -i lustre-utils_2.10.8-1_amd64.deb
    sudo dpkg -i lustre-tests_2.10.8-1_amd64.deb
    sudo dpkg -i lustre-client-modules-4.9.168_2.10.8-1_amd64.deb
7. Upload the modules
    sudo modprobe lnet
    sudo modprobe lustre
    sudo modprobe ldiskfs
8. Update /etc/fstab and mount Lustre. In my case
    fstab:  172.16.1.200 at tcp0:/lustre /depot lustre  defaults,_netdev 0 0
   mount /depot

And that's it. In has been working without problems since July 16.

Thank you very much for the hints.
