debian 6失去大量數據包

  • June 14, 2012

我有一個相當奇怪的問題。我們涵蓋了所有明顯的硬體相關問題（不同的 nic、eth 電纜和交換機），但是我似乎無法阻止 eth 丟棄數據包。

我有 4 台伺服器都完全相同。

driver: e1000e version: 1.2.20-k2 firmware-version: 1.8-0 bus-info: 0000:06:00.0

他們都在執行最新的核心（2.6.32-5-amd64）。

但是他們這樣做：

RX packets:17073870634 errors:0 dropped:14147208 overruns:0 frame:0

另一台伺服器：

eth0      Link encap:Ethernet  HWaddr e0:69:95:05:2f:cb
         inet addr:10.10.10.86  Bcast:10.10.10.255  Mask:255.255.255.0
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:5455209277 errors:0 dropped:375445 overruns:0 frame:0

         Interrupt:20 Memory:d0600000-d0620000

eth1      Link encap:Ethernet  HWaddr 00:1b:21:b7:7a:ce
         inet addr:10.10.0.86  Bcast:10.10.0.255  Mask:255.255.255.0
         UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
         RX packets:15473695728 errors:0 dropped:5808325 overruns:0 frame:0

         Interrupt:17 Memory:d0280000-d02a0000

大量丟棄的數據包。

我嘗試載入最新的驅動程序 1.9.5。這什麼也沒做。

我不確定還能做什麼。

這是我嘗試編譯時遇到的問題：

我以前遇到過這個問題。我想很久以前我從 netdev.c 中刪除了一些東西來讓它工作。但這根本不對。為什麼不能編譯？

編輯（12 年 6 月 14 日）：

它仍然導致嚴重的問題。最近，我們有很高的吞吐量放在盒子上，這導致整個伺服器剛剛鎖定。唯一要做的就是拔掉電源並重新啟動它。這是我發現的消息：

我唯一能想到的就是安裝它。我執行的是 Debian 而不是 Centos，所以我無法安裝“mod-e1000e”驅動程序。對此有更多的了解會很棒。

這是某些 e1000e 晶片組驅動程序的已知問題。去年我遇到了同樣的丟包問題，從原始碼編譯最新的英特爾驅動程序為我解決了這個問題。我目前正在使用 1.5.1 版，沒有任何問題。

編譯完模組後，將其複製到正確的模組目錄（儘管這應該在您編譯時自動發生make install）。我不確定 Debian 上的確切目錄是什麼；在我執行核心 2.6.38-8 的 Ubuntu 系統上，正確的目錄是這樣的，/lib/modules/2.6.38-8-generic/kernel/drivers/net/e1000e/e1000e.ko因此您的目錄可能會略有不同。

現在，在重新啟動之前，請確保以 root 使用者身份解除安裝現有模組modprobe -rv e1000e，然後手動嘗試使用modprobe e1000e. ping 測試現在應該不再顯示丟包。如果在重新啟動系統後，您發現再次遇到丟包，則可能是再次載入了舊版本的模組而不是新編譯的模組，在這種情況下，您應該看看這個先前回答的問題來解決這個問題。

瀏覽一下README英特爾驅動源目錄下的文件；安裝說明很有幫助。
