What is the size of the buffer holding the data, before they're actually written to disk? How can it tackle growing files? If I have a DVR system of 16 channels. They keep writing data to the disk in pieces of video files. I read some spec of xfs. Apart from extend-based allocation, there're allocaiton groups in xfs. I would like to ask, does XFS's allocation groups work similar as JFS's, which would lock an allocation group for individual file write? How does the allocation group in XFS work? And how would it help the fragmentation problem?
