Replicate volume with replica count 2. 1 fuse client.

ran fs-perf-test with number of fd's to be opened as 4096. While it was going on killed a brick , slept and nrought it up. It blocked the entire filesystem.Statedump says there are huge number of calls (around 20,000 call stacks in the statedump, once it was around 35,000) going on most of them being writes.
