fs_newcell - Changes the kernel-resident list of a cell’s database
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]
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
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
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. Refer to the IBM AFS/DFS
Migration Toolkit Administration Guide and Reference for more
information on linking AFS clients to DCE cells using this command or
by editing the /etc/openafs/CellServDB file.
Some commands, such as the klog command, work correctly only when the
information is accurate for a cell in both the CellServDB file and the
-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
-linkedcell <linked cell name>
Specifies the name of the AFS cell to link to a DCE cell for the
purpose of DFS fileset location.
Prints the online help for this command. All other valid options
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 \
The issuer must be logged in as the local superuser root.
