iXOS-JUKEMAN on UNIX

On UNIX iXOS-JUKEMAN cooperates with the standard NFS server. If no

NFS is running, the set-up of the file system is finished. If NFS is running,

you must set up the standard rpc.mountd daemon to cooperate with the

server.

rpc.mountd monitors all file systems, including that of iXOS-JUKEMAN.

If clients mount a network file system they ask rpc.mountd for a root file

handle. This file handle is the key for any further requests to the standard

nfsd or iXOS-JUKEMAN’s NFS-Jukebox-Server. It is not possible to ac-

cess the network file system without this key.

A root file handle can only be generated, is there is a root for the file sys-

tem. Therefore, you must create an empty directory for each view. The hi-

erarchy of the directories to be created must follow the hierarchy of the

views. A subdirectory must be created for each subview. The views are

normally /views_rr for the Rock Ridge format and /views_pc for the

PC format. Any other file names are possible as well (although they do not

comply with the standard server.cfg file and must be entered into this

file accordingly).

If, for example, the views set-up corresponds to that of “Figure 1 - Exam-

ple for different views” on page 70, the following directories must be cre-

ated on the UNIX server:

mkdir /view_1

mkdir /view_2

mkdir /view_3

mkdir /view_3/view_3a

mkdir /view_3/view_3b

Next export a file system by telling rpc.mountd to give the file handles to

clients. Most flavors of UNIX maintain a file /etc/exports (Solaris: see

below) containing all exported file systems. You can simply add a line to

this file containing just the character /. This will tell rpc.mountd to ex-

port all views of the server file system. Please note, that this will also

cause all other directories of the server to be shared. It is recommended

to export only the directories representing the views. To do this add the

following lines to /etc/exports:

/views_pc

/views_rr

This will export the standard views to all hosts. You can also set the ac-

cess permissions for certain hosts:

view_3

view_3b

view_3a

view_1

view_2
