Thanks Lai, I will fix the test script.

[Di Wang]

Ah, I think we can not migrate striped dir yet. that is why we saw these -1 error.

[Di Wang]

Sorry for late response. Ah, hmm, I thought LU-6263 already fixed it. let me check

[Lai Siyao]

This failure can be traced back to http://review.whamcloud.com/#/c/12282/21/lustre/tests/sanity.sh line 679:
test_mkdir -p $DIR/$tdir/remote_dir_$i

this directory used to be created by mkdir, but now by test_mkdir, which will create stripe directory by default, while later 17n tries to migrate file under this directory from MDT1 to MDT0, and mdt_reint_migrate_internal() checks whether parent is remote, if not, it will refuse to migrate. IMHO this check is wrong for striped directory, Di, what's your opinion?
