Gentoo

gentoo上的openvz配額錯誤

  • September 9, 2010

我的系統是 Gentoo amd64，最新更新。我出現了最新的 openvz，並想在我的系統上啟動一個 Ubuntu VPS。我使用的是“基本”配置文件，配額選項設置為預設值，如下：

DISKSPACE="1048576:1153024"

DISKINODES="200000:220000"

QUOTATIME="0"

如果我嘗試創建 CT，我將收到以下錯誤消息。

Creating container private area (ubuntu-10.04-x86_64)
/usr/lib64/vzctl/scripts/vps-create: line 31: 13037 Killed                  
tar -C "$VE_PRVT" ${TAR_OPT} ${OPT} -xf "$PRIVATE_TEMPLATE"
vps-create ERROR: Error in tar --numeric-owner -z -xf /vz/template/cache/ubuntu-10.04-x86_64.tar.gz
Received signal:  9 in /usr/sbin/vzquota
Killed

系統可能看起來還活著，但是一旦有任何 IO 操作，例如用 vim 打開文件，系統就會掛起。

我對openvz真的很陌生，不知道我應該從哪裡開始解決這個問題。

下面是 dmesg 輸出：（系統在該消息後掛起，所以我不確定它是否是完整的輸出）

回答我自己的問題……再次

我查看了 openvz 錯誤，發現人們已經報告了類似的問題。此問題與 ext4 文件系統有關。即使通過 openvz wiki 聲明它在 ext4 上已經穩定，但似乎並非如此。

要解決此問題，只需關閉“磁碟配額”功能，通過在 /etc/vz/vz.conf 文件中設置“DISK_QUOTA=no”，路徑可能會因您的發行版而異。
