UNIX for Dummies Questions & Answers

I have a question and seek help. How many directory can be mounted on one file system on UNIX with solaris 9? For example, I have one file system as /dev/dsk/cieit0a6. I have created one directory as /u01/app/oracle and mounted this directory to cieit06. It works. Then I create another directory as /u02/oradata, can I mount this directory to cieit06 too? Or UNIX file system only allow one mount point to be exist? Thanks.

In general you can only mount a disk to one mount point, although in some circumstances it can be possible to mount the same disk twice, for example if you have multiple paths to the device. In the usual case in order to do this you would need to use a loopback mount of the already mounted filesystem.

Code:

mount -F lofs /u01/app/oracle /u02/oradata

Thanks so much for your advice. Could you be more specific about the command: what are -F and lofs doing in the command line? Can I do this:

mount -F lofs /u01/app/oracle /u02/oradata /u03/oradata /u04/oradata?

Thanks.

man lofs .................................
