ops, sorry the first swapon was a typo (control v) sorry, i know using the swapon lock device, only swapoff and after a mdadm --create could work in this case, but remove the first swapon... just mdadm create, and swap over md device is the point here... the /dev/sda and /dev/sdb was just examples, they can be partitions without problems the point is: using swap at two partitions / disks, is "better" than using a swap over a md raid1? (or any other level?) other point is... swap have a badblock feature? i think it's not linux-raid but linux-vm or something like it... for example if i'm using a disk and swap find a badblock, it will use it? does swap handle bad blocks? it remove the device? continue using it? or change the device priority? -- 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
