Hey! It's Ahad.
Recently I've faced with an issue.
I got a SAN storage. If I want to convert my disk image (qcow2) to a qcow2 one, I would get mismatch while comparing the converted and the base Image.
The point is that this issue only happens in the SAN to SAN conversion. Converting from SAN to local hard server works properly.
Using different flags (-c, -C, -S) of "qemu-img convert" just did their job and fix the issue, but I guess it should work out without using these flags (as I mentioned, SAN to local is okay).
What do you think? We've been thinking that the SAN is the mother issue. What's your idea?
Any help would be appreciated.
Thanks!
