Di, can you take a quick look at this? Is this a regression of some kind?

Comment by Di Wang [ 25/Jun/14 ]

This seems related with lod object initialization process, which unnecessarily load the stripping object, I will cook a patch.

Di, is the http://review.whamcloud.com/10841 patch fixing a critical enough problem that it should land for 2.6.0, or is it just an optimization?

Comment by Di Wang [ 30/Jun/14 ]

Andreas: it is a fix for remote dir unlink error, not just optimization, so probably should go into 2.6.0. The patch still have some problem according to the maloon test, I am trying to figure out now. Thanks.

I checked the console log, should be related with LU-5420, i.e. stale config log caused the OST is not being setup correctly.
