Hi guys,
With recently resumed subpage tests, I'm hitting random failure in
btrfs/266 with subpage tests only. (64K page size with 4K sector size)
The failure rate is around 1/3 ~ 1/5, a "./check -I 10 btrfs/266" run is
always ensured to trigger a failure.
The most common (if not the only) failure is that mirror 3 didn't get
repaired, while mirror 1/2 are properly repaired.
The dmesg doesn't provide enough info since it's rated limited.
What makes it more weird is, the test case itself is already considering
subpage/larger page size, thus except the final verification, everything
is done in 64K block size.
But still it failed to be reproduced on x86_64.
I'm still actively investigating the bug, but if anyone has some clue
it's would be very appreciated.
Thanks,
Qu
