lvm – 为什么不运行xfs_check？

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.

[root@openfiler ~]# xfs_check /dev/backup2/backup2
xfs_check: /dev/backup2/backup2 contains a mounted and writable filesystem

Fatal error -- Couldn't initialize XFS library
