NAS 服务器中 EXT4 加载日志时出错

NAS 服务器中 EXT4 加载日志时出错

我的 NAS 服务器最近拒绝安装外部 USB 驱动器:

root@MyCloudEX2Ultra root # mount -r -t ext4 /dev/sdc1 tmp/
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

root@MyCloudEX2Ultra root # dmesg | tail   
JBD2: Unrecognised features on journal
EXT4-fs (sdc1): error loading journal

-o noload使用传递给 的选项后,它确实能顺利挂载mount

我尝试e2fsck从 NAS 服务器运行它并禁用日志(尽管我不太确定这意味着什么),但显然我的 NAS 服务器没有最新版本的e2fsck

root@MyCloudEX2Ultra root # e2fsck /dev/sdc1
e2fsck 1.42.9 (28-Dec-2013)
/dev/sdc1 has unsupported feature(s): metadata_csum
e2fsck: Get a newer version of e2fsck!

root@MyCloudEX2Ultra root # tune2fs -O ^has_journal /dev/sdc1
tune2fs 1.42.9 (28-Dec-2013)
tune2fs: Filesystem has unsupported read-only feature(s) while trying to open /dev/sdc1
Couldn't find valid filesystem superblock.

此驱动器已在同一 NAS 服务器中安装多次。此外,该驱动器在另一台装有 Linux Mint 的机器上安装完美,并通过了e2fsck测试:

(base) ➜  ~ sudo e2fsck -vf /dev/sdc1                                                                                            [19:27:07]

顺便一提:

有人知道如何解决这个问题吗?由于它是 NAS 服务器(WD MyCloud EX2 Ultra),我无法对其进行更改,因此我宁愿在另一台计算机上以某种方式修改 USB 驱动器。
