I am not able to understand this sentence: on the best of my knowledge, in btrfs the RAID5/RAID6 stripe is composed by several sub-stripes (I am not sure about the terminology to adopt); the number of sub-stripe is equal to the number of the disk. Until now, in btrfs the size of sub-stripe is fixed to 64k, so the size of a stripe is equal to 64k * <number of disks>. So for raid5 the minimum stripe size is 192k, for raid6 is 256k. Why you are writing that the real stripe size is 4kb (may be that you are referring to the be the page size ?). I am quite sure that the problem is the terminology. Could you be so kindly to explain what you are meaning ? Thanks in advance.
