    Description

      A user wrote a very large single stripe file which almost filed an OST.
      We copied the file re-striping and renaming it.
      Removed the original file
      And renamed the file back to the original name.

      We suspect that the original object didn't get deleted because the ost is still %96 full. I fund the object lma and fid.
      fid: [0x20006132a:0x8256:0x0]
      lma: [0x100000000:0xb9bd1:0x0]

      The fid doesn't match any file
      pfe21 ~ # lfs fid2path /nobackupp6 [0x20006132a:0x8256:0x0]
      fid2path: error on FID [0x20006132a:0x8256:0x0]: No such file or directory

      I unmounted the OST ran fsck and remounted it. It didn't help.

      How do we locate the file for the givin fid?
