作者: bailian  出自:

1.挂载一个iso文件：
＃lofiadm -a /export/home/sol_10_807_x86.iso
/dev/lofi/1
使用lofiadm查看：
# lofiadm
Block Device File
/dev/lofi/1 /export/home/sol_10_807_x86.iso
# lofiadm /dev/lofi/1
/export/home/sol_10_807_x86.iso
挂载：
# mount -F hsfs -o ro /dev/lofi/1 /mnt
# df -h
Filesystem size used avail capacity Mounted on
/dev/lofi/1 2.5G 2.5G 0K 100% /mnt
# ls /mnt

卸载：
# umount /mnt
# lofiadm -d /dev/lofi/1
# lofiadm
Block Device File
...

2.在一个文件上创建一个UFS文件系统：
创建一个指定大小的文件:
# mkfile 50m /export/home/test
# lofiadm -a /export/home/test
Block Device File
/dev/lofi/1 /export/home/test
使用newfs创建文件系统：
#newfs /dev/lofi/1
newfs: construct a new file system /dev/rlofi/1: (y/n)? y
/dev/rlofi/1: 102340 sectors in 170 cylinders of 1 tracks, 602 sectors
50.0MB in 11 cyl groups (16 c/g, 4.70MB/g, 2240 i/g)
super-block backups (for fsck -F ufs -o b=#) at:
32, 9664, 19296, 28928, 38560, 48192, 57824, 67456, 77088, 86720,
96352
