sysid - Lists file server machine interface addresses registered in VLDB

|
|
|
The F<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
|
2005-12-14 01:30:20 +00:00
|
|
|
local machine by reading the F</usr/afs/local/NetInfo> file, if it
|
2005-12-08 12:14:33 +00:00
|
|
|
exists. If the file does not exist, the File Server uses the list of
|
2005-12-14 01:30:20 +00:00
|
|
|
network interfaces configured with the operating system. It then removes
|
|
|
|
from the list any addresses that appear in the
|
|
|
|
F</usr/afs/local/NetRestrict> file, if it exists. The File Server records
|
|
|
|
the resulting list in the binary-format F<sysid> file and registers the
|
|
|
|
interfaces in the VLDB.

|
When the Cache Manager requests volume location information, the Volume
|
2005-12-14 01:30:20 +00:00
|
|
|
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.

|
The F<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 F</usr/afs/local> directory from an existing
|
|
|
|
file server machine to a newly installed one, be sure to remove the
|
|
|
|
F<sysid> file from the new machine before starting the C<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>.
