A server was recently transported from location A to B, a long journey that took six months. Things have gone wrong due to nothing being labeled prior to shipment. Yes, I know --- it was done by others, but I am paying the price.
I must salvage the data and need help!
The system booted fine previously, but now it won't boot (not even a grub rescue -- the BIOS simply does nothing, and I've tried selecting each individual member …
我在 BIOS 传统模式下的 Debian 7 上以 JBOD 模式（无硬件突袭）在 2 个 LSI SAS2008 后面的 mdadm 上运行 14 个磁盘 RAID 6。
Grub2 正在使用救援外壳，抱怨“mduuid/b1c40379914e5d18dddb893b4dc5a28f”“不存在这样的设备”。
mdadm 的输出：
# mdadm -D /dev/md0
/dev/md0:

Update Time : Thu Sep 18 19:44:56 …拉我的头发。PHP 从源代码构建，一切正常。现在需要安装 imagick 并且无法安装。
我在内核 3.7.1 和 PHP 5.3.20 上运行 Debian（我的应用程序支持的最后一个版本，不能转到 PHP 5.4）。
pecl install imagick
...
checking ImageMagick MagickWand API configuration program... found in /usr/bin/Wand-config
checking if ImageMagick version is at least 6.2.4... configure: error: no. You need at least Imagemagick version 6.2.4 to use Imagick.
ERROR: `/tmp/pear/temp/imagick/configure --with-imagick' failed
但是，我安装了 6.7.7 版：
# convert --version
Version: ImageMagick 6.7.7-10 2012-11-06 Q16 http://www.imagemagick.org

我还尝试安装最新的测试版（pecl install imagick-beta），结果相同。还尝试了旧版本 2.3.0，结果相同。还尝试下载源代码、phpize 和配置——结果相同。
