Using iXOS-JUKEMAN

iXOS-JUKEMAN 2.2 User Manual Pre.12/9790

4.3.2 UNIX:

In the JUKEMAN directory, call:

./cdnfsd

You must be logged in as root. iXOS-JUKEMAN should display a mes-

sage like this:

Starting iXOS-JUKEMAN Version 2.2 Server, build 1007.12

... iXOS-JUKEMAN started

The server starts up and exports the file systems. The exported file sys-

tems (e. g. /views_rr) can be mounted with NFS (even locally). The

disks do not appear in the directories representing the views (e. g.

/views_rr or /views_pc); these directories’ destiny is to be mount

points for rpc.mountd. These directories must be mounted to access the

disks.

4.4 Modifying the set-up

All settings described in the chapter “Setting up iXOS-JUKEMAN” on page

29 (license keys, buffers and caches, devices, views) are not the subject

of frequent changes. However, the set-up sometimes needs to be

changed, e. g., if new devices should be controlled by iXOS-JUKEMAN.

The following sections tell you what to do in these cases.

4.4.1 Change buffers and caches

Note: If you change the properties of a cache (directory cache, data

cache) or of the IFS buffer all stored data of the relevant cache or

buffer will be lost. All data in the IFS buffer must first be written to

disk using the “cdadm writer flush…” command (see “Burning

disks incrementally” on page 151).

Follow the instructions in “Set up caches and buffers” on page 36.
