NAME

fs_newcell - Changes the kernel-resident list of a cell's database servers

SYNOPSIS

fs newcell -name <cell name> -servers <primary servers>+
[-linkedcell <linked cell name>] [-help]

fs n -n <cell name> -s <primary servers>+
[-l <linked cell name>] [-h]

DESCRIPTION

The fs newcell command removes the Cache Manager's kernel-resident list of database server
machines for the cell specified by the -name argument and replaces it with the database
server machines named by the -servers argument.

Each time the machine reboots, the Cache Manager constructs the kernel list of cells and
database server machines by reading the local /etc/openafs/CellServDB file. This command
does not change the CellServDB file, so any changes made with it persist only until the
next reboot, unless the issuer also edits the file. The output of the fs listcells command
reflects changes made with this command, because that command consults the kernel-resident
list rather than the CellServDB file.

This command can introduce a completely new cell into the kernel-resident list, but cannot
make a cell inaccessible (it is not possible to remove a cell's entry from the kernel-
resident list by providing no values for the -server argument). To make a cell
inaccessible, remove its entry from the CellServDB file and reboot the machine.

If the -name argument names a DCE cell, then the -servers argument names DFS Fileset
Location (FL) Server machines. The -linkedcell argument specifies the name of the AFS cell
to link to a DCE cell for the purpose of DFS fileset location.

CAUTIONS

Some commands, such as the aklog or klog.krb5 commands, work correctly only when the
information is accurate for a cell in both the CellServDB file and the kernel-resident
list.

OPTIONS

-name <cell name>
Specifies the fully-qualified cell name of the AFS or DCE cell.

-servers <primary servers>+
Specifies the fully-qualified hostnames of all AFS database server machines or DFS
Fileset Location (FL) Server machines for the cell named by the -name argument. If FL
Server machines are specified, the local machine must be running the AFS/DFS Migration
Toolkit Protocol Translator.

-linkedcell <linked cell name>
Specifies the name of the AFS cell to link to a DCE cell for the purpose of DFS
fileset location.

-help
Prints the online help for this command. All other valid options are ignored.

WINDOWS

The fs newcell command on Windows differs from the Unix version in a few ways.

fs newcell with no arguments discards the existing cell information. The Windows client
will reload a cell's information the next time it needs the server list for a cell.

Secondly, in addition to accepting the Unix options, fs newcell on Windows accepts the
following options:

-dns
Adds the new cell to the cache manager, and obtains the VLDB server information from
DNS.

-registry
Adds the new cell to the cache manager, and also saves the cell configuration data in
the registry for use the next time the service restarts.

-vlport <cell VLDB server port>
Specifies an alternate port number at which the cell's volume location database
servers are listening.

-fsport <cell fileserver port>
Specifies an alternate port number at which the cell's file servers are listening.

EXAMPLES

The following example changes the machine's kernel-resident list of database server
machines for the ABC Corporation cell to include the machines "db1.abc.com" and
"db2.abc.com":

% fs newcell -name abc.com -servers db1.abc.com db2.abc.com

The following example links the DCE cell "dce.abc.com" to the AFS cell "abc.com". The AFS
client contacts the Fileset Location (FL) servers "db1.dce.abc.com" and "db2.dce.abc.com"
for fileset location information as it interprets a DFS pathname.

% fs newcell -name dce.abc.com \
-servers db1.dce.abc.com db2.dce.abc.com \
-linkedcell abc.com

PRIVILEGE REQUIRED

The issuer must be logged in as the local superuser root.
