Hi, I'm trying to create a disk and map some sectors to have errors on them. I tried this, echo "0 100000 linear /dev/sdb 0 100000 480081250 error"| dmsetup create bad_disk device-mapper: reload ioctl failed: Invalid argument Command failed I have put in the right arguments but not sure why it fails. Could someone please guide me how I can do this. Thanks, Yathi |
