WD My Cloud libc.so.6 救砖实录
本文仅针对 WD My Cloud Gen1。
症状
使用 apt-get 安装软件时，更新了 libc 到 2.19 导致的。

There is a solution if there is a ssh connection and a working share.
You should download file http://ftp.altlinux.org/pub/people/boyarsh/wd/libc.so.633 (or extract /lib/arm-linux-gnueabihf/libc-2.17.so from firmware image and name it libc.so.6) and put it on share.
Let it be /DataVolume/shares/Public/libc.so.6
Then you can type in you ssh connection:
export LD_PRELOAD=/DataVolume/shares/Public/libc.so.6
and then you can execute most commands.
Personally, I uploaded a tar image of rootfs extracted from firmware to share, untared it and rsynced /lib /usr and /var/lib from it to device rootfs.
You can also go to /lib/arm-linux-gnueabihf/ and relink all links from 2.19 to 2.17
just a to help other to “relink”
ldconfig -l -v /lib/arm-linux-gnueabihf/libc-2.17.so
下面是翻译
- 前提是还有ssh连接和samba共享可用
- 找到libc-2.17.so，重命名为libc.so.6，放置于/DataVolume/shares/Public/libc.so.6（这时应该还可以访问samba共享文件夹）
- export LD_PRELOAD=/DataVolume/shares/Public/libc.so.6
- 现在也许可以运行大多数命令，也许不行
- 尝试重链接所有2.19 到 2.17（删除所有2.19，用 ln 重新链接到2.17，有很多个文件）
- ldconfig -l -v /lib/arm-linux-gnueabihf/libc-2.17.so（我在输入这条命令后可以运行大多数命令）
补充：所有 relink 完成后，系统基本可用，重启成功，唯独 samba 服务不可用，恢复原厂固件后一切正常
