    Description

      OST2 died. When I run lfs getstripe it lists some files as on OST2, but lfs find cannot find them.

      [root@blah ~]# lfs getstripe /mnt/blah/Ac_270_res.txt
      /mnt/blah/Ac_270_res.txt
      lmm_stripe_count: 1
      lmm_stripe_size: 1048576
      lmm_stripe_offset: 2
      obdidx objid objid group
      2 137992 0x21b08 0
      [root@blah ~]# lfs find --obd lustre-OST0002 /mnt/blah
      [root@blah ~]# lfs find -r --obd lustre-OST0002 /mnt/blah # the -r works since it uses getstripe
      lfs find: -q, -r, -v options deprecated. Use 'lfs getstripe' instead.
      /mnt/blah/Ac_270_res.txt

      I think the lfs find should be able to find the files if lfs getstripe can.

            It appears that the "lfs find -mdt" handling added in http://review.whamcloud.com/1646 caused lfs to open() and fstat() every file, when it was only needed for "-mdt".

            I'm going to fix this under LU-6134.

            This is on OST2 but I have no OST1, in other words I have a hole in my lustre. So I think this problem is probably exactly what is seen in LU-1427.
