This is weird, the code is from simple_stripe_full_stripe_len(),
which
means the chunk map must be RAID0 or RAID10.
In that case, their sub_stripes should be either 1 or 2, why we
got 0 there?
In fact, from volumes.c, all sub_stripes is from
btrfs_raid_array[],
which all have either 1 or 2 sub_stripes.
Although the code is old, not the latest version, it should
still not
cause such problem.
Mind to retest with my branch to see if it can be reproduced?
https://github.com/adam900710/linux/tree/refactor_scrub
we tested head of this branch:
d6e3a8c42f2fad btrfs: scrub: rename scrub_bio::pagev and
related members
and:
fdad4a9615f180 btrfs: introduce dedicated helper to scrub
simple-stripe based range
on this branch.
by attached config.
still reproduce the same issue.
attached dmesgs FYI.
Still failed to reproduce here.
Those btrfs/07[0123] tests are already in scrub/replace group, thus I
ran them almost hourly during the development.
Although there are some ASSERT()s doing extra sanity checks, they
should
not affect the result anyway.
Thus I pushed a branch with more explicit BUG_ON()s to catch the
possible divide by zero bugs.
(https://github.com/adam900710/linux/tree/refactor_scrub_testing)
Mind to give it a try?
in our tests, it seems one BUG_ON you added is triggered
(full dmesg attached):
What the heck...
It's indeed some weird extent mapping has its sub-stripes as 0...
I must be insane or there is something fundamental wrong.
Mind to try that branch again? I have updated the branch, now it will
trigger BUG_ON() as soon as it finds a chunk mapping with
sub_stripes == 0.
I'm wondering if it's old btrfs-progs involved (which may not properly
initialize btrfs_chunk::sub_stripes) now.
below BUG print was caught by your new patch (detail dmesg attached):
Thank you very much for the detailed report!
The triggered BUG_ON() means, we're getting sub_stripes == 0, for
unrelated chunks (in this case, it's DUP from sys chunk array, from the
full dmesg).
And from the code context, it's from super-block, thus there must be
something wrong with the mkfs.btrfs.
But unfortunately, I re-compiled my btrfs-progs v5.15.1, retried, and
still no reproduce.
Mind to share the result of "btrfs ins dump-tree -t chunk /dev/sdb2" and
"btrfs ins dump-super -f /dev/sdb2" just after the mkfs.btrfs call of it?
As the BUG_ON() mostly means, the result from mkfs.btrfs is not correct.
We have added the "btrfs ins dump" commands after mkfs btrfs call, and
got below log:

All the sub_stripes values are correct.
So the on-disk values are correct, not something wrong in btrfs-progs.

But we still got a sub_stripes value as 0, from the super block
sys_chunk_array.
I have no idea why this could even happen.
There used to be some bug in misc-next, that makes extent buffer read to
always return 0.
But I don't think that's still in my tree.
Anyway, I have updated the refactor_scrub_testing branch, with one new
RFC patch, and rebased its base.
(Of course, I tested it locally using the scrub and replace group
without crash)
Mind to give it a try?
This branch will no longer trust the sub_stripe value from on-disk data,
and the branch base is much newer, definitely without the old possible
read extent buffer value bug.
we have tested the new head of refactor_scrub_testing branch
(55a862df9ec6af btrfs: don't trust sub_stripes from disk)
and found the issue is gone.
