FS_NEWCELL(1) AFS Command Reference FS_NEWCELL(1)NAMEfs_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
/usr/vice/etc/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.
