[Lustre-discuss] LAST_ID issue on lustre 1.8.7
All, We seem to be having a bad failure here. Here is some info from lctl and from looking at the lov_objid for our /work filesystem: ===============================[root at nas-0-1 ~]# mount /mnt/lustre/work/mdt [root at nas-0-1 ~]# lctl dl 0 UP mgs MGS MGS 5 1 UP mgc MGC10.100.255.89 at o2ib 87c71980-91c9-51ae-bf2c-37113d7a06e7 5 2 UP mdt MDS MDS_uuid 3 3 UP lov work-mdtlov work-mdtlov_UUID 4 4 UP mds work-MDT0000 work-MDT0000_UUID 3 5 UP osc work-OST0000-osc work-mdtlov_UUID 5 6 UP osc work-OST0003-osc work-mdtlov_UUID 5 7 UP osc work-OST0005-osc work-mdtlov_UUID 5 8 UP osc work-OST0002-osc work-mdtlov_UUID 5 9 UP osc work-OST0009-osc work-mdtlov_UUID 5 10 UP osc work-OST0001-osc work-mdtlov_UUID 5 11 UP osc work-OST0007-osc work-mdtlov_UUID 5 12 UP osc work-OST0006-osc work-mdtlov_UUID 5 13 UP osc work-OST0008-osc work-mdtlov_UUID 5 14 UP osc work-OST0004-osc work-mdtlov_UUID 5 [root at nas-0-1 ~]# !umount umount /mnt/lustre/work/mdt [root at nas-0-1 ~]# mount -t ldiskfs /dev/VG_hamming/work_mdt /mnt/lustre/work/mdt [root at nas-0-1 ~]# od -Ax -td8 /mnt/lustre/work/mdt/lov_objid 000000 77090836 87265628 000010 104094987 84525048 000020 70980680 36265791 000030 36262683 36068567 000040 35917014 26909787 000050 [root at nas-0-1 ~]# ============================================= What concerns me is that we have 10 OSTs for the filesystem, but there appear to only be 6 showing up in the lov_objid... Am I reading this correctly? If so how do I recover those ''missing'' OSTs. Brian

All, Ignore that. My stress is making me think slowly... Still issues, but less in the ''panic'' mode..
