--- Additional comment from Susant Kumar Palai on 2018-04-27 07:08:47 EDT ---

There are good enough checks in the fix-layout code path to eliminate ENOENT and ESTALE errors. But the same was missing from gf_defrag_settle_hash function. Since the the directory in question is deleted as part of rm -rf *, settle_hash failed.

debug log snippet.

Comment 6 Prasad Desala 2018-05-15 12:49:53 UTC 
Verified this BZ on glusterfs version 3.12.2-9.el7rhgs.x86_64.

Followed the same steps as in the description, remove-brick process on the nodes completed successfully without any failures.

Hence, moving this BZ to Verified.
