[lustre-discuss] can't install Lustre 2.12.7

[Thomas Roth]

Hi Riccardo

(no solution for you problem here)
out of curiosity, I have just upgraded a test server to centos 7.9 and Lustre 2.12.7.

Kernel is 3.10.0-1160.42.2.el7.x86_64

But I installed kmod-lustre, lustre, kmod-lustre-osd-zfs. The Lustre modules went to /lib/modules/3.10.0-1160.25.1.el7.x86_64/extra, with symlinks to 
the weak-updates of the previous kernel (3.10.0-1160.2.1.el7.x86_64).

I symlinked those directories in 3.10.0-1160.25.1.el7.x86_64/extra to 3.10.0-1160.42.2.el7.x86_64/extra and mounted my OSTs.
= Dirty workaround, if you quickly need 2.12.7, but of course not sustainable - at some point the kernel version will have deviated too much and dkms 
is needed again.

Regards
Thomas
