NAME¶
sysid - Lists file server machine interface addresses registered in VLDB
DESCRIPTION¶
The
sysid file records the network interface addresses that the File
Server (
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
/var/lib/openafs/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
/var/lib/openafs/local/NetRestrict
file, if it exists. The File Server records the resulting list in the
binary-format
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.
CAUTIONS¶
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
/var/lib/openafs/local directory from an
existing file server machine to a newly installed one, be sure to remove the
sysid file from the new machine before starting the "fs" trio
of processes, which includes the
fileserver process.
A maximum of 15 file server interface addresses can be registered in the VLDB.
