我正在运行一个完全更新的Ubuntu 9.04“Jaunty”i686服务器.我在LVM组中有一个名为/ dev / mapper / vg0-bigthree的XFS卷.
如果我启动到单用户模式并确保已卸载卷,则每次尝试运行xfs_check时仍会收到以下内容：
- $sudo xfs_check /dev/mapper/vg0-bigthree
- xfs_check: /dev/mapper/vg0-bigthree contains a mounted and writable filesystem
- fatal error -- couldn't initialize XFS library
为了彻底,我开始尝试运行
- $sudo fsck.xfs /dev/mapper/vg0-bigthree
- If you wish to check the consistency of an XFS filesystem or
- repair a damaged filesystem,see xfs_check(8) and xfs_repair(8).
在转向xfs_check之前.
另外,我可以确认在mount的输出或卷的设备或挂载点的/ etc / mtab中没有出现.
解决方法
这就是我在我的系统上解决这个问题的方法.在尝试运行xfs_check时,我看到了与您相同的问题.显然fs没有安装.似乎autofs或nfs仍然保留在文件系统上,一旦它们被停止,检查就会运行.
