How to stop callbacks from being suppressed
by ballsystemlord from LinuxQuestions.org on (#5T5ZS)
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:
Code:echo 1000 > /proc/sys/kernel/printk_ratelimit_burst
echo 500 > /proc/sys/kernel/printk_ratelimitBut I'm getting the identical callback suppression message with another check:
Code:echo check > /sys/devices/virtual/block/mdX/md/sync_action2: 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.
