All, I have a line showing up on my device list for a device that is not mounted: 45 AT osp SCRATCH-OST0002-osc-MDT0000 SCRATCH-MDT0000-mdtlov_UUID 1 In fact all bits of that filesystem are unmounted and that will not go away. If I mount that OST, it doesn't change anything. The entry showing a status of 'AT' is still there 34 UP osd-ldiskfs SCRATCH-MDT0000-osd SCRATCH-MDT0000-osd_UUID 10 35 UP lod SCRATCH-MDT0000-mdtlov SCRATCH-MDT0000-mdtlov_UUID 4 36 UP mdt SCRATCH-MDT0000 SCRATCH-MDT0000_UUID 3 37 UP mdd SCRATCH-MDD0000 SCRATCH-MDD0000_UUID 4 38 UP qmt SCRATCH-QMT0000 SCRATCH-QMT0000_UUID 4 39 UP osp SCRATCH-OST0000-osc-MDT0000 SCRATCH-MDT0000-mdtlov_UUID 5 40 UP osd-ldiskfs SCRATCH-OST0001-osd SCRATCH-OST0001-osd_UUID 5 41 UP obdfilter SCRATCH-OST0001 SCRATCH-OST0001_UUID 5 42 UP osp SCRATCH-OST0001-osc-MDT0000 SCRATCH-MDT0000-mdtlov_UUID 5 43 UP osp SCRATCH-OST0003-osc-MDT0000 SCRATCH-MDT0000-mdtlov_UUID 5 45 AT osp SCRATCH-OST0002-osc-MDT0000 SCRATCH-MDT0000-mdtlov_UUID 1 What is a status of 'AT' and how do I get that OST back online and active? I have tried --writeconf, activate/deactivate fo all OSTs and the MDT. I've run e2fsck on the backing filesystem with no errors.
