Status: Resolved

Environment:

NFS server/Lustre client (1.8), Lustre server 2.1, nfs client.

Severity: 3
Rank (Obsolete): 6357

 Description   

When re-exporting Lustre over NFS (v3), the NFS client gets EBADHANDLE when attempting to access a file/dir that the same client just created.

The problem seems to stem from this:
llite_nfs.c:276:ll_get_parent()) failure -22 inode 144412065124057097 get parent

If you wait long enough, then the NFS client can access the file. But also, if the NFS server/Lustre client accesses the file/dir, then the NFS client will work right thereafter.
Reexport Lustre over NFSv3.
On NFS client:

  1. mkdir foo8
  2. date
    Sat May 5 08:09:46 CDT 2012
  3. cd foo8
    -bash: cd: foo8: Unknown error 521
  4. cd foo8
    -bash: cd: foo8: Unknown error 521
