[LU-1675] Unknown error 521 (EBADHANDLE) on new file/dir access with re-exported Lustre over NFS

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

• Trackbacks: Lustre 1.8.x known issues tracker While testing against Lustre b18 branch, we would hit known bugs which were already reported in Lustre Bugzilla https://bugzilla.lustre.org/. In order to move away from relying on Bugzilla, we would create a JIRA
