What changes are proposed in this pull request?
Now we unpin and set min replication to 0 if we failed due to IO related reasons. (such as UFS not available, file does not exist etc).
Why are the changes needed?
Previously if a replication job fails, it would be rescheduled again and again, causing Denial of Service.
Does this PR introduce any user facing changes?
Yes, the user would expect certain files unpinned or adjusted if it becomes unavailable.
