我们正在淘汰一些富士通 Primergy 服务器。当然，在此之前，我们要确保硬盘被彻底清除。但是似乎没有办法一一格式化硬盘，因为 RAID 阵列控制器没有被 DBAN 等实用程序检测到。我已经删除并重新创建了 RAID。我的问题是，这就够了吗？
需要注意的几点：
这些是租用的服务器，因此不能选择物理销毁硬盘。
我曾尝试为控制器配置 JBOD，但似乎它不支持它。
最新的 Ubuntu、Debian、Gparted 或 DBAN 无法识别控制器或磁盘。
在 Ubuntu 12.04 服务器中，Squid3 的 logrotate 不起作用。当我注意到分区已从 squid3 日志中填满时，我发现了问题。强制 logrotate 会产生以下错误：
~# logrotate -f /etc/logrotate.d/squid3
error: error running shared prerotate script for '/var/log/squid3/*.log
这是完整的调试输出：
~# logrotate -f /etc/logrotate.d/squid3 -d

知道可以在这里检查什么吗？谢谢。
