挂接和卸载文件系统发生在系统启动和关闭时。
系统启动时,将读取/etc/vfstab文件。这个文件记录系统要挂接的文件系统。因此/etc/vfstab文件中的文件系统将自动挂接。也可以从命令行方式下人工挂接文件系统。
不加参数的mount显示系统目前已经挂接的文件系统。
# mount
/ on /dev/dsk/c0t3d0s0 read/write/setuid/largefiles/logging on Mon Nov 18
17:58:19 1998
/usr on /dev/dsk/c0t3d0s6 read/write/setuid/largefiles/logging on Mon Nov 18
17:58:19 1998
/proc on /proc read/write/setuid on Mon Nov 18 17:58:19 1998
/dev/fd on fd read/write/setuid on Mon Nov 18 17:58:19 1998
/var on /dev/dsk/c0t3d0s1 nolargefiles/read/write/setuid on Mon Nov 18 17:58:19
1998
/opt on /dev/dsk/c0t3d0s5 setuid/read/write/largefiles on Mon Nov 18 17:58:20
1998
/tmp on swap read/write on Mon Nov 18 17:58:20 1998
/pns on dbserver:/export/pse soft/nosuid/remote on Mon Nov 18 19:04:36 1998
nolargefiles参数将使文件系统中所有新建的文件小于2G字节。
# mount -o nolargefiles /dev/dsk/c0t3d0s7 /export/home
使用这个参数可能出现错误,原因是由于文件系统包含了大于2G的文件
要挂接在/etc/vfstab中已有的某个文件系统时,只需要用命令
# mount /export/home
/etc/vfstab文件格式
#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot ops
#/dev/dsk/c1d0s2 /dev/rdsk/c1d0s2 /usr ufs 1 yes -
/proc - /proc proc - no -
fd - /dev/fd fd - no -
swap - /tmp tmpfs - yes -
/dev/dsk/c0t3d0s0 /dev/rdsk/c0t3d0s0 / ufs 1 no -
/dev/dsk/c0t3d0s6 /dev/rdsk/c0t3d0s6 /usr ufs 1 no -
/dev/dsk/c0t3d0s3 /dev/rdsk/c0t3d0s3 /export ufs 5 yes -
/dev/dsk/c0t3d0s7 /dev/rdsk/c0t3d0s7 /export/home ufs 5 yes -
/dev/dsk/c0t3d0s5 /dev/rdsk/c0t3d0s5 /opt ufs 8 yes -
/dev/dsk/c0t3d0s1 - - swap - no -
umount卸载文件系统
# umount /dev/dsk/c0t3d0s7
或
# umount /export/home
如果文件系统中某个文件正在使用,则不能卸载这个文件系统。
总结:如何增加一个新的硬盘
1. Set up hardware, including setting switches and attaching cables. Follow the instructions included with the new disk.
2. Reboot the system using the command boot -r. This command will restart the system using the reconfigure (-r) option.
3. Partition the disk.
4. Create the new file systems as required.
5. Edit the /etc/vfstab file as required.
6. Reboot the system.
光驱、软驱的使用
Solaris有个服务进程管理光驱和软驱,当光盘或软盘放入机器中,系统会自动的挂接上,挂接的目录是:
Media Location
CD-ROM /cdrom/cdrom_name
Diskette /floppy/floppy_name
如:
#cd /cdrom/cdrom0
管理进程叫卷管理服务器,其脚本位于/etc/init.d/volmgt。
