Hi Milan,
I'm trying to inject random sector errors using device mapper.
Suppose I want to inject some 50 errors on random sectors, is their a
way to do
this without having to reload the table every time.
Thanks,
Yathi

I'm trying to create a disk and map some sectors to have errors on

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
Try
echo -e "0 100000 linear /dev/sdb 0\n100000 480081250 error"| dmsetup
create bad_disk
