REVIEW: http://review.gluster.org/12186 (cluster/tier do not flag migration error on already migrated file) posted (#2) for review on release-3.7 by Dan Lambright (dlambrig) COMMIT: http://review.gluster.org/12186 committed in release-3.7 by Dan Lambright (dlambrig) ------ commit ef231e41af79803a0e1e8829920b67e736578109 Author: Dan Lambright <dlambrig> Date: Wed Sep 16 10:26:44 2015 -0400 cluster/tier do not flag migration error on already migrated file In some cases a brick will try to migrate a file that has already been migrated. This is a legal case, e.g. when both bricks are replica pairs.

Description of problem: ========================= When we have many files, say about 5000 files in hot tier, and when detach tier is issued, we can see many files as failed in detach tier status, in this case about 2000 files. But all files are migrated, if we check the backend bricks. So, is this spurious errors or a serious miss?
