-----------------------------------------
Hi [~xyao]
Thanks for the review.
I have addressed the review comments.
{quote}ChunkManagerImpl.java
Line 172: should we increment the readTime around here for the volume io stat?
{quote}
readTime, I have incremented it after read data from the file, just before
returning data. Let me know if you still want it changed?
ChunkUtils.java Line 168-169
file.read(buf, data.getOffset()).get();
volumeIOStats.incReadTime(Time.monotonicNow() - timeTaken);
