我的 EXT4 分区之一上有一个目录出现错误，但fsck似乎无法修复它。
# fsck -ClV -vpf /dev/mapper/enc_vols-home

我还尝试卸载驱动器并fsck再次运行，但它没有帮助 - 它仍然抱怨该文件夹。
该分区在 RAID1（镜像）上的 LUKS 上的 LVM2 上为 ext4：
sdb sdb /dev/sdb 8:16 linux_raid_member
└─md127 md127 /dev/md127 9:127 crypto_LUKS
└─enc_vols dm-0 /dev/mapper/enc_vols 253:0 LVM2_member
└─enc_vols-home dm-1 /dev/mapper/enc_vols-home 253:1 1015.4G 1.8T ext4
sdc sdc /dev/sdc 8:32 linux_raid_member
└─md127 md127 /dev/md127 9:127 crypto_LUKS
└─enc_vols dm-0 /dev/mapper/enc_vols 253:0 LVM2_member
└─enc_vols-home dm-1 /dev/mapper/enc_vols-home 253:1 1015.4G 1.8T ext4
阵列中的两个驱动器都不到 2 年，并且在 SMART 中没有显示任何错误，尽管我仍然没有运行fsck -c。
为什么没有fsck找到错误，如何清理这个目录？
