My questions are as follows: 1) If you're creating a completely new array (e.g. raid-1) on new partitions that aren't formatted, do you still have to sync? I'm having difficulty finding information on why and when a sync is needed. I was under the impression a sync is only needed when there's existing information on one or more of the drives. 2) If there used to be information on each device, but has since been repartitioned, so that new partitions and a raid device can be created... is there any way to prevent mdadm from asking if you really want to create the array? Using `--force' doesn't seem to help. mdadm: /dev/sda1 appears to contain an ext2fs file system size=1464840K mtime=Fri Nov 13:04:09 2009 mdadm: /dev/sdb1 appears to contain an ext2fs file system size=1464840K mtime=Fri Nov 13:04:09 2009 Continue creating array? As a side note, there really isn't an existing ext3 fs on it, but there used to be. To re-use the device, I issued the following commands: > parted -s /dev/sda mklabel msdos > parted -s /dev/sda mkpart primary ext3 0 1500 -- 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
