    Description

      EC zone manager tries to get XAttr of an inode to determine the EC policy, which doesn't work with symlinks. This patch has a simple fix to get rid of test failures.

      Ideally we should also add logic to disallow creating symlinks in several EC-related scenarios. But since symlinks are disabled in branch-2 and will likely be disabled in trunk, this step is skipped now.

      The patch also fixes a small test error around getBlockReplication
