Might be more than it is worth but what if you made a small program/file server that addressed portions of the "larger" file as their own file in a temporary directory. On write you would have to preallocate the file on the disk and write eatch section to it's respective range. "Chunks" would be simplified by having a pre-copy size and a "Chunk number" appended on the end of each chunk. Used to write to the correct location in the destination. Everything in else could remain the same. You would just use the "Split/Bulk Copy" program to copy from source to destination. Getting better with plan9 but not enough so to implement something like this or know if it would work. Just a thought. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Te69bb0fce0f0ffaf-Mb8a0447d7180b423909022ff Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
