mounting sun UFS file system under FreeBSD stable/10

[Dmitry Morozovsky]

Dear colleagues,

I have (from one of my friends) block copy of dead disk apparently used at old 
Sun Solaris Server:

root at moose:/ar/backup/komarov# file -s sun72g.img
sun72g.img: Unix Fast File system [v1] (big-endian), last mounted on /, last 
written at Sun Jan 30 15:51:07 2011, clean flag 253, number of blocks 10242144, 
number of data blocks 10086988, number of cylinder groups 202, block size 8192, 
fragment size 1024, minimum percentage of free blocks 1, rotational delay 0ms, 
disk rotational speed 167rps, TIME optimization

however, trying to mount or fsck the image fail:

root at moose:/ar/backup/komarov# mdconfig -l -v
md0     swap      128M
md1     vnode      68G  /ar/backup/komarov/sun72g.img
root at moose:/ar/backup/komarov# fsck_ufs -n /dev/md1
** /dev/md1 (NO WRITE)
Cannot find file system superblock
ioctl (GCINFO): Inappropriate ioctl for device
fsck_ufs: /dev/md1: can't read disk label
root at moose:/ar/backup/komarov# mount -r /dev/md1 /mnt
mount: /dev/md1: Invalid argument

Any hints? Thanks!
