I'm using CentOS 6.5, with the stock infiniband, lustre 2.5.3, and a logical volume (to allow for snapshots and backups). The module for lnet contains the following "options lnet networks=tcp0(em1),o2ib0(bond0)" Though the mds/mdt seems to mount I see the following error... ~] mount -t lustre /dev/lustrepool/lustrevol /mdt ~] dmesg LDISKFS-fs (dm-1): mounted filesystem with ordered data mode. quota=on. Opts: Lustre: lustre-MDT0000: used disk, loading Lustre: MGS: non-config logname received: params Lustre: Skipped 1 previous similar message LustreError: 11-0: lustre-MDT0000-lwp-MDT0000: Communicating with 0@lo, operation mds_connect failed with -11. ~]lctl dl 0 UP osd-ldiskfs lustre-MDT0000-osd lustre-MDT0000-osd_UUID 8 1 UP mgs MGS MGS 5 2 UP mgc MGC<proper ip for ib interface>@o2ib c2f57f70-a066-ea38-0d9b-e54f0f52ae81 5 3 UP mds MDS MDS_uuid 3 4 UP lod lustre-MDT0000-mdtlov lustre-MDT0000-mdtlov_UUID 4 5 UP mdt lustre-MDT0000 lustre-MDT0000_UUID 5 6 UP mdd lustre-MDD0000 lustre-MDD0000_UUID 4 7 UP qmt lustre-QMT0000 lustre-QMT0000_UUID 4 8 UP lwp lustre-MDT0000-lwp-MDT0000 lustre-MDT0000-lwp-MDT0000_UUID 5 Thank you, Kurt J.
