Hello,
Unfortunately for me, my RAID-6 array has several mis-matches due to my HDD cable coming loose. I need to determine the affected area, then use debugfs to fine the affected files.
I know how to do all of the above. But I don't know how to get the Linux kernel to output all the the affected sector info to dmesg.

I get several "handle_parity_checks6: XX callbacks suppressed" messages.

1: How do I disable the callback suppression?

I tried changing:
But I'm getting the identical callback suppression message with another check:
2: Considering RAID-6 has 2 parity drives, couldn't the kernel recalculate the correct data using 3 of the drives without bothering me about these data problems?



PS: Please no, "You should backup your data messages." I had to replace my PCIe-to-HDD adapter and shipping from China is slow so I couldn't do a recent backup.

This is a shot in the dark, as I certainly am not competent to answer your question, but this article on callbacks at kernel.org might be a good starting point.

Thanks, but that's for patching the Linux Kernel.

there is also /proc/sys/net/core/message_{burst,cost}
Try setting the cost to zero and stand back for a flood.
