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.
Then run /etc/amd/amd_start -f to restart Amd. This makes it unnecessary
to reboot all the nodes that have the new map.
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
To correct this problem, add the filesystem to /etc/exports and run
-a
on the server.
root@sp21n09 / > cd auto/one
root@sp21n09 /auto/one > ls -l
