From 4c33c68e20a3b84e0e19a4a6c5cce6a9766f1042 Mon Sep 17 00:00:00 2001 From: Sunil Kumar Acharya Date: Thu, 1 Feb 2018 17:44:27 +0530 Subject: functional/disperse: verifies full heal functionality This test case validates that full heal crawls whole filesystem instead of just scanning indices/xattrop.
