[Disksim-users] adding dummy writes at RAID level

[Yiying Zhang]

Hi,

I need to add dummy writes (writing to the same block twice with the same
value) to some device (e.g. the shadowed device) of RAID. I copied the
write request and added it in logorg_shadowed. When the dummy write has
the same block number as the original one, the program failed at some
point. With different block number, it is working fine.
I've been debugging with it for some time but no luck so far. Any ideas
what can go wrong when adding dummy writes with same block number? I've
removed the check for request already present in queue.

Thanks
