Other than the superblocks, does 'mdadm --create' harm existing data? It would seem that a fault tolerant array would need to be synchronized but I don't recall this happening when I created raid6 arrays and it also seems that you don't really care if parts of the array that haven't been written yet are in sync. The '--assume-clean' option would seem to be what I want but the man page say it's for --build only. I want to assemble an array from various damaged pieces to find the least damaged configuration so I don't want any device writing or sync to happen. I've been editing superblocks by hand but it's a bit of a pain :-) Thanks for any help. - 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
