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

[Hugo R Hernandez]

Morning Lustre Community!

Has anyone experienced any issue when trying to build Lustre 2.14 with ZFS
2.0.4 on CentOS7.9 running any of these two kernels:  3.10.0-1160.6.1.el7
(tested during release) and 3.10.0-1160.25.1.el7 (latest).  Is there any
'special recipe' you need to follow for a proper Lustre build from source?
When we built for 2.10+ we used to use these flags when configuring:

--with-zfs
--with-zfs-obj
--with-spl
--with-spl-obj

but ZFS 2.0.x now includes SPL as part of it as previously they were
separated packages.

Any hint on how to address this problem?  Help is greatly appreciated!

Thanks,
-Hugo
