hi folks I have a simple doubt..Why is there an indirection scheme applied in i-node instead of another structure.. I know tht triple level of indirection works great for very large files... but are there any performance reasons that indirection scheme is applied.. The reason I m asking this is that I need to modify the inode such that at the last indirection level, instead of data block pointers, I need to have address of a block containing X data block pointers instead of (blocksize/4) data block pointers.. Does this have any drastic effect on the file system performance?? bye a Linux lover -- Kernelnewbies: Help each other learn about the Linux kernel.
