我有一個轉儲的 ext4 分割映像：mmcblk0p5 我可以掛載該映像，但它始終是唯讀的。於是我查看了dmesg，有這樣的內容：
EXT4-fs error (device loop0): ext4_init_inode_table:1340: comm ext4lazyinit: Something is wrong with group 0: used itable blocks: 467; itable unused count: 0
所以我運行一個e2fsck -ccy mmcblk0p5
e2fsck 1.42.9 (4-Feb-2014)
mmcblk0p5: recovering journal

mmcblk0p5: ***** FILE SYSTEM WAS MODIFIED *****
mmcblk0p5: 1623/44802 files (0.0% non-contiguous), 138293/179194 blocks
似乎找不到任何錯誤，只能清除錯誤日誌。如果我再次安裝它，則會出現相同的錯誤。我該如何修復這個檔案系統？這是掛載/卸載鏡像檔後的tune2fs結果。

如果我做tune2fs -e continue mmcblk0p5。然後安裝並在其上建立一些資料夾。 e2fsck 會給出一些錯誤：
e2fsck -ccky mmcblk0p5

但這個錯誤無法修復，它始終存在。知道如何解決這個問題嗎？
