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:
