Hello List
How can I get the kernel to read/write some data immediately to disk without caching it in the kernel memory.
I like to access one harddrive with two motherboards and like to have a shared partition that will be writen to by one motherboard and read by an other motherboard - but Linux seems to prevent that.
I don't like to mount any partition (because of the filesystem check warnings) and will instead write raw data with "dd". Oh, and I don't like to flush ALL buffers, because this computer will be a redunant web-server that strongly needs buffers (for this reasons AFAIK I can't use flushb and sync).
thank you for any help or redirections to other lists/newsgroups
