Hi Dharshan,

Thanks for your comment.

I should’ve specified that we’re using MongoDB 3.2 which introduced fsyncLock for WiredTiger.

Even though we have journaling enabled I personally prefer to flush to the filesystem before taking a snapshot. If I can avoid leaving some pending work, albeit little, to mongod then I’m happy to do so for such a small cost.
