我运行 btrfs-check 并收到以下错误:
$ sudo btrfs check --progress --force /dev/nvme0n1p7

没有详细说明哪个文件/路径被破坏。我该如何手动修复它?
更新1:当我尝试确定损坏的范围时,我使用以下脚本查找与上述缺陷 inode 关联的所有文件:
#!/bin/bash
inode_list="14139676 14141114 14141174 14141175 14141186 14148125 14148148 14148168 14148190 14154429 14154456 14154459 14154460 14154468 14154499 14156088 14156134 14156137 14157822 14157857 14157858 14157859 14157869 14157870 14157882 14157919" # replace with your inode numbers
directory="/home" # replace with your directory
for inode in $inode_list
do
echo "looking for inode $inode"
find $directory -inum $inode
done
令人惊讶的是,没有发现文件:
$ sudo ./findINode.sh

这怎么发生的?这是否意味着可以执行任何“危险”修复选项而不会丢失数据?
更新2:所以我继续删除它们:
inode_list="14139676 14141114 14141174 14141175 14141186 14148125 14148148 14148168 14148190 14154429 14154456 14154459 14154460 14154468 14154499 14156088 14156134 14156137 14157822 14157857 14157858 14157859 14157869 14157870 14157882 14157919" # replace with your inode numbers
directory="/home"
for inode in $inode_list
do
echo "deleting inode $inode"
find $directory -inum $inode -delete
done
但问题仍然存在,所有被假定删除的 inode 仍然在 btrfs 检查中报告,这是由有缺陷的实现引起的吗?删除它们的替代方法有哪些?
