然而，当我跑步时，rpm -q vnc-server我得到：

我在这里遵循说明

如果我运行 iostat，我会看到：

看起来像 dm-0，dm-2 是罪魁祸首。很可能是读变成了写，因为 iotop 显示：

我的 fstab 是这样的：

/dev/mapper/VolGroup-lv_root    /   ext4    usrjquota=quota.user,jqfmt=vfsv0    1   1

/dev/sdd1               /home4                  auto    auto,defaults         0 0

问题是dm-0、dm1、dm-2是哪一个？我想我只是将默认值更改为 defaults,relatime，但是哪些行？

如果我执行 ls -l /dev/disk/by-id/

我有

lrwxrwxrwx. 1 root root  10 Dec 26 05:03 dm-name-VolGroup-lv_home -> ../../dm-2
lrwxrwxrwx. 1 root root  10 Dec 26 05:03 dm-name-VolGroup-lv_root -> ../../dm-0

/dm-0 到 dm-2 有 2 个条目。我想知道为什么。我想我得到了我现在需要的东西。我怀疑，交换不是问题。Root 和 home 是一个有点奇怪的问题，因为 /home 中的所有帐户都已被转移到其他地方。

我有4个硬盘。我只是在所有这些中创建一个分区。我用ext 3格式化它们。然后我重写fstab

好吧，我会在 fstab 中添加几行

/home4                  /dev/sdd1               auto    auto,defaults         0 5

我这样做正确吗？

有什么改进的建议吗？

我想知道为什么 /dev/sda1 现在出现在 fstat 中。

所以我只是改变这个，然后重新启动服务器，对吗？

这是 fdisk -l 的结果

重启后还是无法访问/homne2 /home3/和/home4

一切也变得如此缓慢。

首先，auto 和 defaults 之间有一个空格。我删除了它并再次重新启动。现在一切正常。仍然没有/home2

如果我输入 mounts

我有

root@host [/etc]# mount
/dev/mapper/VolGroup-lv_root on / type ext4 (rw,usrjquota=quota.user,jqfmt=vfsv0)

更新：看起来我犯了一个错误。挂载名称应位于第二列。在任何人回答之前，让我先解决这个问题。

这就是 whm apache status 所说的：

我已将 whm 中的最大连接数和最大服务器数分别增加到 1500 和 3000。

服务器大量使用硬盘进行缓存。它只有 10 mbps 连接。但是，我懒得增加它，因为它只有 38.9 kB/秒。

如果瓶颈确实是 IO，我可以检查吗？

服务器还大量卷曲其他站点并缓存结果。

服务器响应速度很快，但有一点延迟。

IO 似乎是问题所在：iostat -xdk 1 20

%util 通常会达到 100%。所以这似乎是瓶颈。

Vmstat 似乎不是问题所在：

看起来像一个名为 KGP(M)E-D16 stop 之类的硬件。在谷歌上查看显示它是主板。

我还应该检查什么？我已经将此报告给 fdcservers.net。

他们声称这是内核错误。而不是硬件问题。什么内核错误？为什么会导致服务器崩溃？我应该怎么办？

检查网卡的驱动程序我得到了这个

话虽如此，

硬件名称：KGP(M)E-D16是华硕主板。此外，如果您搜索硬件名称：KGP(M)E-D16，此页面排名前 3。
