2.10.x servers should interoperate with 2.12.x clients – many sites use this option.

I choose b2_10 because my lustre server is 2.10. I guess only b2_10 matches the server. Am I right? ---------------------------------- Thank you and best regards Song, Huiming ________________________________ From: Peter Jones <pjo...@whamcloud.com> Sent: Tuesday, October 22, 2019 0:05 To: Huiming Song <s0nghuim...@hotmail.com>; lustre-discuss@lists.lustre.org <lustre-discuss@lists.lustre.org> Subject: Re: [lustre-discuss] Build fails on Lustre 2.10.x and Ubuntu 18.04 I suggest that you use the b2_12 branch instead -that should be able to build against more current kernels than b2_10 From: lustre-discuss <lustre-discuss-boun...@lists.lustre.org> on behalf of Huiming Song <s0nghuim...@hotmail.com> Date: Monday, October 21, 2019 at 2:21 AM To: "lustre-discuss@lists.lustre.org" <lustre-discuss@lists.lustre.org> Subject: [lustre-discuss] Build fails on Lustre 2.10.x and Ubuntu 18.04 Hi, I'm trying to build lustre from source @b2_10 branch and Ubuntu 18.04/19.04. After meeting many difficulties, I can start make the build. Then in 'make debs', I received the error as of following: ... rm -f liblustreapitmp.a ar cru liblustreapitmp.a liblustreapi.o liblustreapi_hsm.o liblustreapi_nodemap.o liblustreapi_json.o liblustreapi_layout.o liblustreapi_lease.o liblustreapi_util.o liblustreapi_kernelconn.o liblustreapi_param.o ../../libcfs/libcfs/util/string.o ../../libcfs/libcfs/util/param.o liblustreapi_ladvise.o liblustreapi_chlg.o ar: `u' modifier ignored since `D' is the default (see `U') ranlib liblustreapitmp.a rm -f liblustreapi.a liblustreapi.so gcc -shared -o liblustreapi.so `ar -t liblustreapitmp.a` gcc: error: string.o: No such file or directory gcc: error: param.o: No such file or directory Makefile:1834: recipe for target 'liblustreapi.a' failed I have searched for the issue in the mailing list. I searchech 'Ubuntu 18.04', 'string.o', 'params.o', but no issue matches my case. Could you help to give any comments on this error? Thanks in advance. ---------------------------------- Thank you and best regards Song, Huiming
