Hallo I am recently encountering an issue with the ext4 usage case. I want not only sequentially LBA allocation in a single file, but also expect that the LBA sequential allocation between the two files, which means that the last LBA of the previous file should be adjacent to the first LAB of the block of the next file. But from my testing, the sequential LBA of block allocation is easily met, but the LBA sequential allocation between files is not to ext4. The gab in LBA between two seq write (two files) is very huge, sometimes the gap is over 2GB space. I notice ext4 never allocates the LBA of the block between two files sequentially on my usage case. who knows the reason of this? and if there is a configuration of ext4 related to this scenario? or please tell me which ext4 function I should study, and see if I can find the reason. thanks in advance for any suggestions. Thanks, Lee
