Comment 1 Mohammed Rafi KC 2015-11-10 10:03:33 UTC

I/O's were failed after attaching the tier is because, the fix-layout was not complete for some directories. So the directory structure was not proper on hot tier, and then trying to access such directories will result a failure.

Fix : 

after a nameless lookup if we get an incomplete layout, we will trigger a healing after getting full path from the server.
