I looked at the code in 2.6.32 and I can't find the related bits in handle_stripe6(). The prexor int isn't defined, and the checks after set_bit(R5_Wantwrite, &dev->flags); aren't issued. I don't know enouch about this code to see what's going on. I'm also not sure what really triggers this bug. I tried setting up a raid6, failed two drives, starting to write a bunch of deterministic data to the drives and started to rebuild it - no errors could be detected, neither in metadata or data.
I have a vm setup with lucid for this purpose, and I can allow access to it for deveopers wanting to test. roy -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1364091 Title: Possible RAID-6 corruption Status in “linux” package in Ubuntu: Triaged Status in “mdadm” package in Ubuntu: Invalid Bug description: It seems there's a bug in newer kernels that may lead to corruption on RAID-6.
