[lustre-discuss] Lustre 2.15.3: patching the kernel fails

[Andreas Dilger]

The first yes toon to ask is what is your end goal?  If you just want to build only a client that is mounting to an existing server, then you can disable the server functionality:

    ./configure --disable-server

and it should build fine.

If you want to also build a server, and *really* want it to run Debian instead of eg. Rocky 8, then you could disable ldiskfs and use ZFS:

    ./configure --disable-ldiskfs

You need to have installed ZFS first (either pre-packaged or built yourself), but it is less kernel-specific than ldiskfs. 

Cheers, Andreas
