sysid - Lists file server machine interface addresses registered in VLDB
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The sysid file records the network interface addresses that the
|
||
|
|
File Server (B<fileserver> process) registers in the Volume Location
|
||
|
|
Database (VLDB) for the local file server machine.
|
||
|
|
|
||
|
|
Each time the File Server restarts, it builds a list of interfaces on the
|
||
|
|
local machine by reading the B</usr/afs/local/NetInfo> file, if it
|
||
|
|
exists. If the file does not exist, the File Server uses the list of
|
||
|
|
network interfaces configured with the operating system. It then
|
||
|
|
removes from the list any addresses that appear in the
|
||
|
|
B</usr/afs/local/NetRestrict> file, if it exists. The File
|
||
|
|
Server records the resulting list in the binary-format B<sysid> file
|
||
|
|
and registers the interfaces in the VLDB.
|
||
|
|
|
||
|
|
When the Cache Manager requests volume location information, the Volume
|
||
|
|
Location (VL) Server provides all of the interfaces registered for each server
|
||
|
|
machine that houses the volume. This enables the Cache Manager to make
|
||
|
|
use of multiple addresses when accessing AFS data stored on a multihomed file
|
||
|
|
server machine.
|
||
|
|
|
||
|
|
=head1 CAVEATS
|
||
|
|
|
||
|
|
The sysid file is unique to each file server machine, and must
|
||
|
|
not be copied from one machine to another. If it is a common practice
|
||
|
|
in the cell to copy the contents of the B</usr/afs/local> directory
|
||
|
|
from an existing file server machine to a newly installed one, be sure to
|
||
|
|
remove the B<sysid> file from the new machine before starting the
|
||
|
|
B<fs> trio of processes, which includes the B<fileserver>
|
||
|
|
process.
|
||
|
|
|
||
|
|
Some versions of AFS limit how many of a file server machine's
|
||
|
|
interface addresses that can be registered. Consult the I<IBM AFS
|
||
|
|
Release Notes>.
