Hi, is there a documentation available on how mdadm stores data? E.g. 1. super-block 2. offset of first block on each drive 3. whether mdadm stores blocks as raw data or stores some kind of metadata associated with each block e.g. disk 1 -> data_block1 immidiatelly followed by data_block 5 or metadata_for_block_1 | data_block 1 | metadata_for_block_5 | data_block 5 | 4. how and where mdadm stores its backup superblock 5. what klind of XOR algorithm is used by mdadm thanks, Marek -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
