Hi I am trying to dynamically add error injection to my virtual disk(LVM) for testing+ debugging purpose. I saw "faulty" personality module in the kernel and was wondering if there was any documentation on its usage. I am not looking to set up a RAID but a simple mapped device. So the basic use case is that I need to be able to dynamically add/remove error sectors and also be able to have granular error configuration like read error, read+write error etc. thanks in advance Jojy -- 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
