不久前,我在 Linux 系统上设置了休眠状态。它一直工作得很好,直到今晚我安装了另一个硬盘,它改变了设备节点名称。因此,现在在启动时,我收到一条消息,内容是(我没有写下确切的措辞),couldn't stat /dev/sda3
并要求我输入休眠设备节点名称或按 Enter 键继续,而不从休眠状态恢复。这种情况发生在普通启动上,而不是从休眠状态恢复(我没有尝试从休眠状态恢复,并且当系统无法正确识别要从休眠状态恢复的设备时,恐怕它根本无法正常工作)。当我使用休眠时,我使用软件包提供的 /usr/sbin/hibernate 脚本hibernate
(版本2.0+15+g88d54a8-1
已安装);我不记得以任何特定方式真正设置过它。
这是因为当我安装新硬盘时,它在检测顺序中比我拥有根文件系统和交换空间的SSD更早出现。这不应该构成问题,特别是当我到处使用稳定的 /dev/disk/by-*/ 名称时——至少我是这么认为的。
我对 /boot 和 /etc 进行了 grep 搜索,但没有一个匹配项看起来是相关的。
/proc/swaps 显示 /dev/sdb3,这是该分区现在已知的名称。 /etc/fstab 使用其 /dev/disk/by-id/ata-*-part3 名称对其进行命名。
我正在使用相当最新的 Debian Wheezy。这是我的 /etc/default/grub:

如果我能找到合适的地方进行更改,这应该是一个简单的更改。所以,只需从哪里获取该设备名称的恢复代码和我该如何改变它以反映新的现实?
(我通过交换所涉及的设备来解决这个问题,使 SSD 在检测顺序中排在第一位,但我仍然对这个问题的答案感兴趣。)
答案1
基本上,您的原始文件是由安装时/etc/uswsusp.conf
调用的脚本编写的。要查看脚本,请检查。dpkg
uswsusp
/var/lib/dpkg/info/uswsusp.config
要半自动更新,请使用:
dpkg-reconfigure uswsusp
或者,手动编辑它,然后使用:
update-initramfs -u
/usr/share/doc/uswsusp/README.Debian
我真诚地鼓励您也阅读。
