The root cause was that after chunkDesc eviction, the offset between memory representation of chunk layout (via chunkDescs in memory) was shiftet against chunks as layed out on disk. Keeping the offset up to date is by no means trivial, so this commit is pretty involved. Also, found a race that for some reason didn't bite us so far: Persisting chunks was completel unlocked, so if chunks were purged on disk at the same time, disaster would strike. However, locking the persisting of chunk revealed interesting dead locks. Basically, never queue under the fp lock. Change-Id: I1ea9e4e71024cabbc1f9601b28e74db0c5c55db8 |
