assume i want to rebuild the same raid device on a completely different system, cloning for example. "mdadm --detail /dev/md0" appears to be the only command that will display all of the information needed to completely rebuild a raid device with the exact same characteristics (persistent superblock, chunk size, layout, etc.). has the format of this file changed from back level versions? can i expect to see the same format in the future? also, is there any way with mdadm to create a raid device that does not have persistent superblock? with raidtools there is a flag to indicate whether you want a persistent superblock. - 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
