Even still it's useful during implementation to think of the use case of that remote client having read a file and caching and holding a read lock on that file, say 1GB in size, and then another client wanting to update say, 1KB in the middle of the file. It would be beneficial for that 1GB file to have a small (but still practical) stripe size so that the amount of cache that needs to be thrown away to accommodate the write is relatively small. b. -------------- next part -------------- A non-text attachment was scrubbed...
