Hi, I can reliably get LVM/mdraid to trigger a 'rescheduling sector' and mark one half of my raid bad when running the iotests. (e.g. iotest 175). The raid refreshes and reads fine; and I've boiled it down to a single O_DIRECT read, which in some cases turns into a BUG.
I've reported it at the kernel bugzilla; https://bugzilla.kernel.org/show_bug.cgi?id=221535 Note there's a ~10 year old bug as well where others have reported RAID corruption triggered with qemu in some cases, which is https://bugzilla.kernel.org/show_bug.cgi?id=99171 So, take care!
