Hi. I upgraded our OSS servers from 2.1.4 to 2.1.6 (RHEL6). Things looked OK until I discovered the IB clients are no longer able to communicate with the upgraded servers. Seeing messages like this in the OSS logs: Jul 19 19:28:55 ki-oss01 kernel: LustreError: 2248:0:(o2iblnd_cb.c:2903:kiblnd_cm_callback()) 192.168.115.100@o2ib: REJECTED 28 Jul 19 19:28:55 ki-oss01 kernel: LustreError: 2248:0:(o2iblnd_cb.c:2903:kiblnd_cm_callback()) Skipped 64 previous similar messages Jul 19 19:30:01 ki-oss01 kernel: LustreError: 2248:0:(o2iblnd_cb.c:2903:kiblnd_cm_callback()) 192.168.115.120@o2ib: REJECTED 28 The IB clients will mount but df -h or any file dereferencing will hang. "lfs df" on the IB clients also shows the OSTs as inactive. tcp communications are just fine. I've also tried upgraded the client version from 2.1.4 to 2.1.6 - no difference. The message almost looks like it is related to some security policy. Any suggestions before I roll back to version 2.1.4? ------- Yemi _______________________________________________ HPDD-discuss mailing list HPDD-discuss(a)lists.01.org https://lists.01.org/mailman/listinfo/hpdd-discuss
