btrfs-progs: Allow open_ctree to return fs_info even chunk tree is corrupted
Current open_ctree_fs_info() won't return anything if chunk tree root is corrupted. This makes some function, like btrfs-find-root, unable to find any older chunk tree root, even it is possible to use system_chunk_array in super block. And at least two users in mail list has reported such heavily chunk corruption. Although we have 'btrfs rescue chunk-recovery' but it's too time consuming and sometimes not able to cope with a specific filesystem corruption. This patch adds a new open ctree flag, OPEN_CTREE_IGNORE_CHUNK_TREE_ERROR, allowing fs_info to be returned from open_ctree_fs_info() even there is no valid tree root in it. Also adds a new close_ctree() variant, close_ctree_fs_info() to handle possible fs_info without any root. Signed-off-by: Qu Wenruo <> [ adjusted error messages ] Signed-off-by: David Sterba <>
