Hello Michael Lustre 2.12.8 does not support Linux 5.15 More recent Lustre versions support up to Linux 5.11 but not further. See these tickets for 5.12 and 5.14 support. https://jira.whamcloud.com/browse/LU-14651 https://jira.whamcloud.com/browse/LU-15220
It is possible to manually backport patches to support some 5.x kernels with 2.12 but this is not trivial. I don't know what is your current project but it will be much easier for you if you can target an older Linux kernel and focus on kernel used by major distro. Ubuntu 20.04 is using 5.11 by example.

Looks to me like something in the build process has changed. The failure occurs in configure line 14390. From the log: configure:14390: cp conftest.c build && make -d _module_/tmp/lustre-2.12.8/build LUSTRE_KERNEL_TEST=conftest.i LDFLAGS= LD=/usr/bin/ld -m elf_x86_64 CC=gcc -f make: *** No rule to make target '_module_/tmp/lustre-2.12.8/build'. Stop. configure:14393: $? = 2 For some reasons the construct "make -d _module_/${PWD} .." does no longer work (it works on same OS with 4.18 RH8.3 kernel). If I replace it with something like "make -d modules .." It works, modules are build, but the subsequent test for ${PWD}/conftest.i fails Any help appreciated Happy new year Michael ------------------------------------------------------------------------ Michael Hebenstreit Senior Cluster Architect Intel Corporation, MS: RR1-105/H14 TSACG 1600 Rio Rancho Blvd SE Tel.: +1 505-794-3144 Rio Rancho, NM 87124 UNITED STATES E-mail: [email protected] _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
