Figure 94. Sample A m d Map File
The example in Figure 94 will mount the directory /tony (and its
subdirectories) on the Control Workstation and on the nodes as /auto. On
the Control Workstation, the original directory (/tony) will be linked to /auto.
4. After creating a new A m d m a p file, use
dsh
to copy the file to each node.
Then run /etc/amd/amd_start -f to restart Amd. This makes it unnecessary
to reboot all the nodes that have the new map.
5. If one of the following error messages shown in Figure 95 is returned when
trying to access a filesystem mounted by Amd, ensure that the filesystem
has been exported on the server.
root@sp21n09 / > cd /auto/one
ksh[2]: /auto/one: permission denied
root@sp21n09 / > cd /auto
root@sp21n09 /auto > cd one
ksh[2]: one:
not found
Figure 95. Error Messages When the Filesystem Is Not Exported
To correct this problem, add the filesystem to /etc/exports and run
exportfs
-a
on the server.
root@sp21n09 / > cd auto/one
root@sp21n09 /auto/one > ls -l
