如何在linux中mount FREEBSD分区?

ggw

在BSD中可以通过编译内核来mount ext3/2分区.可是在linux下如何mountBSD分区呢?我想最大的困难在于BSD的分区是slice的.而在linux中根本不认这些slice而一认成一个BSD分区.请问如何在linux中mount FREEBSD分区?

linux对FreeBSD分区的支持不好， 还是别想了！最好是都使用一个使用fat32格式的共享分区。

ggw

BSD的是默认是UFS文件系统吧。不知现在的内核支持不？要是可以的话直接在linux内核编译时加上UFS支持就行了。我到LINUX下看看内核支不支持先。

ggw

我看过了有
默认的是only read。我试试先

mount -t ufs -o ufstype=44bsd /dev/hdaX /mnt
but with fbsd 5.x, I'm not sure this still works... since freebsd 5.x use ufs2 instead of ufs .

好像行不通

这么大的硬盘， 分个fat32格式的分区来在各系统间传递文件！

well, your freebsd slice is hdb3 (view by linux), but this slice include  normal partition (/, /usr...etc...) and also swap for freebsd, so "mount -t ufs -o ufstype=44bsd /dev/hdb3 /mnt/freebsd" will not work.

The best way is rainren's methode : "create at least a slice for data (with fat32 or ufs , not ufs2)" and according to your config to remount it.

ggw

收到.我去看了freebsd-howto,里面说mount ufs2要用这样的命令
mount -t u2fs  /dev/hd?? /mnt/freebsd
它会包括所有的slice 而这个功能必须要求内核2.1.87以上.可是我的内核已是最新的了(2.6)还是不能用这个.要下载个ufs的补丁才行.可是我找不能.howto原文如下
5. Mounting filesystems
5.1 Mounting UFS filesystems under Linux
Unfortunately the UFS driver in the Linux 2.0.xx kernels do not include support for FreeBSD. When you try to mount a FreeBSD filesystem, you just get some error messages (the filesystem actually gets mounted, but you cannot do anything with it.) This problem has been solved in the newer Linux kernels (version 2.1.87 and higher.)

There is another version of the UFS driver for Linux 2.0.xx kernels (xx <= 30) on SunSite. It is called U2FS and the current version is u2fs-0.4.3.tar.gz. A version of U2FS (ufs-0.4.4.tar.gz) for Linux 2.0.31 and higher (2.0.xx; not 2.1.xx) can be found at this site along with further information about U2FS (and UFS.)

Now you have to build a new kernel with support for the U2FS filesystem and BSD disklabels. See section Installing and preparing Linux for more information on this. You can leave out UFS filesystem support from the kernel when you use U2FS.

When you have installed the new kernel, you can mount your UFS filesystems (all the partitions in the FreeBSD slice except the swap partition) with a command like this:

mount -t u2fs /dev/hda8 /mnt

You should use a command like

mount -t ufs /dev/hda8 /mnt

if you use a Linux kernel version 2.1.87 or higher.
The UFS (and U2FS) driver is read-only. That is; you can read from the UFS filesystems but you cannot write to them. An experimental read-write UFS driver has replaced the read-only driver in Linux kernels version 2.1.112 and higher; writing to FreeBSD partitions is supported from version 2.1.127.

我的英语很不好.不知我的理解有没有错呢?里面只是说可能解决.
请问那个网站比较好下载tar.gz文件.
