Hi Marc,
Hi Qu, thanks for your answer and looking at this.
Did btrfs-debug-tree also has the crash?
If not, would you please attach the output if it doesn't contain
classified data.
Do you need anything else before I wipe the filesystem and start over?
1) kernel is fixed not to crash
2) btrfs check --repair segfaults
3) btrfs-debug-tree ends with assert
Thanks,
Marc
Would you please take the following output?
1) btrfs check output
With error message if it happens.
2) btrfs check --repair output
Full output until segfault.
3) btrfs-debug-tree output
With assert output.
At least this should help us to figure out what's wrong with on-disk data.
Thanks,
Qu
Sure thing:
btrfs-debug-tree /dev/mapper/crypt_sdd1 > /tmp/tree.out
