    Description

      I'm testing the 2.3.63 tag with a 2.1.3 client I can't mount this client.

      All servers are installed in 2.3.63.

      My Lustre client is in 2.1.3.

      Once my MDS/MGS is started and my OSS too I cannot mount the Lustre filesystem.

      On MDS/MGS:

      [root@falcao2 ~]# lctl dl
      0 UP osd-ldiskfs MGS-osd MGS-osd_UUID 5
      1 UP mgs MGS MGS 7
      2 UP mgc MGC10.5.0.2@tcp 2d7d64f3-854c-60f8-ba9f-b04827fb7012 5

      7 UP mdd falcaofs-MDD0000 falcaofs-MDD0000_UUID 4

      10 UP osp falcaofs-OST0002-osc-MDT0000 falcaofs-MDT0000-mdtlov_UUID 5
      11 UP lwp falcaofs-MDT0000-lwp-MDT0000 falcaofs-MDT0000-lwp-MDT0000_UUID 5

      On OSS:

      [root@falcao3 ~]# lctl dl
      0 UP osd-ldiskfs falcaofs-OST0002-osd falcaofs-OST0002-osd_UUID 5
      1 UP mgc MGC10.5.0.2@tcp 15818cd1-7577-8e13-aa40-601eca445800 5

      6 UP lwp falcaofs-MDT0000-lwp-OST0001 falcaofs-MDT0000-lwp-OST0001_UUID 5
      7 UP lwp falcaofs-MDT0000-lwp-OST0002 falcaofs-MDT0000-lwp-OST0002_UUID 5

      Trying mount from my 2.1.3 client:

      [root@austin7 ~]# mount -t lustre falcao0@tcp:/falcaofs/ /falcaofs/

      Client's log:

      LustreError: 3675:0:(mgc_request.c:275:config_log_add()) logname falcaofs/-client is too long

      Maybe I missed something. Don't hesitate to ask for more information if needed.
