[lustre-discuss] Lustre version 2.14 support for CentOS 7

[Hugo R Hernandez]

Peter, I have been trying to get 2.14 ready with ZFS 2.0.4 on CentOS 7.9
but I have encountered a couple of issues.  This is what I have been doing:

ZFS:
Install dependency packages
git clone https://github.com/openzfs/zfs.git
git checkout remotes/origin/zfs-2.0-release
./autogen.sh
./configure
make && make rpms
install libzfs4, zfs-2.0.4, zfs-dksm (have tried also installing kmod-zfs*,
libuutil3, libnvpair3, libzpool4)

Lustre:
git clone git://git.whamcloud.com/fs/lustre-release.git
git checkout remotes/origin/b2_14
./autogen.sh
./configure --enable-ldiskfs --with-zfs --enable-quota --enable-utils
--enable-gss --enable-snmp --with-zfs-obj=/var/lib/dkms/zfs/2.0.4/3.10.0-
1160.24.1.el7.x86_64/x86_64
make <<< here I have linking breaks

I get an error like this:

fatal error: sys/byteorder.h: No such file or directory
 #include <sys/byteorder.h>

I wondering if I'm doing this on an updated CentOS 7.9 host running
kernel 3.10.0-1160.24.1.el7 instead of the one used for testing during
release cycle:  3.10.0-1160.6.1.el7.  is there something I'm missing or
doing wrong in this case?  Should I be able to compile then build RPMs i.e.
using now available 3.10.0-1160.25.1.el7 so we can have happy security
folks by using the latest kernel?

Please advise.  Thanks in advance!
