swap开机时无法激活

[linux5588]

开机是提示swap激活失败。
fdisk -l 还能显示swap分区

df 看不到swap信息

还有开机时几个失败。闪的太快，没有看到呢？
我不知道在/var/log/里看哪个日志可以找到失败的信息呢

代码： 全选

sudo swapon /dev/sda10

看看什么效果。

[linux5588]

代码： 全选

sudo swapon /dev/sda10

看看什么效果。

[arch@arch ~]$ sudo swapon /dev/sda10
swapon: /dev/sda10: swapon failed: Device or resource busy

[arch@arch ~]$ sudo mkswap /dev/sda10
/dev/sda10: Device or resource busy

df 是看不到swap以及未挂载的设备的。
请贴出详细的fdisk -l

以及以及，free -m

[arch@arch ~]$ sudo fdisk -l

看吧。。就这么多了

[poweroff]

你的swap不是已经激活了吗！！！！

你的/etc/fstab中估计已经写好了swap的自动挂载。

可是我开机启动时显示的是失败呀。

自从有一次看到用文件方式来做swap之后，我的机器上就再没有过swap分区，只有swap文件。

启动时ctl+s定屏，ctl+q取消，定下来慢慢看错误……
