dmesg (x86-64, kernel 5.3.9)

This happened during a balance of a newly converted ext4 partition:

btrfs-convert /dev/sda7
mount /dev/sda7 /mnt/mychroot/
btrfs subvol delete /mnt/mychroot/ext2_saved/
btrfs filesystem defrag -r -czsdt /mnt/mychroot/ext2_saved/
btrfs filesystem balance start /mnt/mychroot/

Unfortunately no detailed stracktrace as it's no debugging kernel on this machine:

Comment 2 Erhard F. 2020-01-04 23:38:49 UTC
Now with a full stacktrace from kernel 5.5-rc4, same partition (restored from a backup before) again at balancing:

# mount -o compress=zstd:1 /dev/sda6 /mnt/mychroot/
# btrfs filesystem balance start /mnt/mychroot/
WARNING:

	Full balance without filters requested. This operation is very
	intense and takes potentially very long. It is recommended to
	use the balance filters to narrow down the scope of balance.
	Use 'btrfs balance start --full-balance' option to skip this
	warning. The operation will start in 10 seconds.
	Use Ctrl-C to stop it.

Still happens on kernel 5.5.2, btrfs-progs 5.4.1.
Comment 6 Marcos Souza 2020-02-12 03:14:38 UTC
Wenruo, IIUC, at this point, the only way to get the fs to function is to try "btrfs check" and "check --repair" if the first one didn't fix?

Found a similar issue here[1]. What called my attention was "BTRFS error (device sda6): eb 7024910336 invalid extent inline ref type 182", which is similar the bug in [1], since the last pointer of the leaf seems to be damaged.

Thanks,

Comment 7 Qu Wenruo 2020-02-12 05:08:45 UTC
The bad report mechanism makes the result really hard to read for human.

But at least, after going through all the hassle, the point is pinpointed to these lines:
Jan 05 00:31:23 supah kernel:         item 44 key (7022157824 169 0) itemoff 14852 itemsize 33
Jan 05 00:31:23 supah kernel:                 extent refs 1 gen 195 flags 258
Jan 05 00:31:23 supah kernel:                 ref#0: shared block backref parent 7022157824
Jan 05 00:31:23 supah kernel:                         (parent 7022157824 is NOT ALIGNED to nodesize 16384)

If the parent block number is not aligned to nodesize, it will trigger the warning.

However such requirement is completely wrong.
The chunk itself can starts at an offset not aligned to nodesize. It only needs to be aligned to sector size.

Thus this is a false alert.

I'll fix the related bug soon.

Thanks.

Here is the fix:

Comment 9 Erhard F. 2020-02-13 21:43:38 UTC
Just applied the fix to 5.5.3 and did the balance again. Now it works well. Thanks!
Comment 10 Erhard F. 2020-03-12 22:02:51 UTC
Would be nice if this patch can be added to mainline kernel soon.
Comment 11 Zhang Boyang 2020-03-25 10:50:25 UTC
I also encountered the exactly same problem. I converted my ext4 filesystem according to the instructions on btrfs wiki. The original ext4 fs is about 4TB and almost full. The version of btrfs-progs is 5.4.1, and the version of my kernel is 4.15 (shipped with Ubuntu 18.04).

...

...

...

I backported the patch to my ubuntu kernel. The balance seemed worked fine.

I think the btrfs wiki should be modified to address this problem, or other people may run into the same problem.

By the way, I found a problem in the patch. In the last part of the patch, the if condition is not modified.

The fix if merged will automatically get backported to all affected kernels.

A notice in btrfs wiki won't hurt though.

Fixed and resent, hopes it get merged this time.

v2 was sent recently, on the way to mainline, tagged for stable.
