Debian測試下如何掛載ufs文件系統？

為了將我的安裝/dev/sda4 在/mnt/ufs_mountDebian Testing 上，我嘗試了以下命令（它在 Debian Jessie 下執行良好）：

modprobe ufs
mount -r -t ufs -o ufstype=ufs2 /dev/sda4 /mnt/ufs_mount

和：

mount -t ufs -o ufstype=ufs2 /dev/sda4 /mnt/ufs_mount

但我得到這個錯誤：

mount: /dev/sda4 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sda4,
  missing codepage or helper program, or other error

  In some cases useful info is found in syslog - try
  dmesg | tail or so.

的輸出dmesg | tail：

[ 1136.965142] ufs: ufs_fill_super(): bad magic number
[ 1255.758946] ufs: ufs_fill_super(): bad magic number

     mount -t ufs -o ufstype=sun|sunx86|44bsd|ufs2|5xbsd|old|hp|nextstep|nextstep-cd|openstep ...

     >>>WARNING<<< Wrong ufstype may corrupt your filesystem, default is ufstype=old

編輯 我的sources.list：

deb http://httpredir.debian.org/debian/ stretch main
deb-src http://httpredir.debian.org/debian/ stretch main

deb http://security.debian.org/debian-security stretch/updates main
deb-src http://security.debian.org/debian-security stretch/updates main

並且uname -a：

Linux debian 4.6.0-1-amd64 #1 SMP Debian 4.6.4-1 (2016-07-18) x86_64 GNU/Linux

ufsDebian測試下如何掛載文件系統？

根據linux 下 mount freebsd slice partition，您可能需要指定一個偏移量到分區中。

partx -l應該能夠辨識文件系統的扇區偏移量，您需要將其乘以 512。您可以使用-o offset=$((512*sector_offset))- 假設您正在使用bash或類似的 shell 將其作為掛載選項傳遞。
