FS(1) AFS Command Reference FS(1)NAMEfs - Introduction to the fs command suite
DESCRIPTION
The commands in the fs command suite constitute the main administrative
interface to the Cache Manager on an AFS client machine, which is
responsible for fetching AFS data from file server machines on behalf
of applications running on the client machine.
There are several categories of commands in the fs command suite:
· Commands to set and report how the Cache Manager interacts with
server machines: fs checkservers, fs getcellstatus, fs getcrypt, fs
getserverprefs, fs listcells, fs newcell, fs setcbaddr, fs setcell,
fs setcrypt, fs setserverprefs, fs sysname, fs uuid, and fs wscell.
· Commands to administer access control lists (ACLs): fs cleanacl, fs
copyacl, fs getcalleraccess, fs listacl, and fs setacl.
· Commands to administer server machines, volumes or partitions that
house a given file or directory: fs diskfree, fs examine, fs
getfid, fs listquota, fs quota, fs setquota, fs setvol, fs whereis,
and fs whichcell.
· Commands to administer the local client cache and related
information: fs bypassthreshold, fs checkvolumes, fs cscpolicy, fs
flush, fs flushall, fs flushvolume, fs getcacheparms, fs
listaliases, fs newalias, and fs setcachesize.
· Commands to administer volume mount points: fs lsmount, fs mkmount,
and fs rmmount.
· Commands to control monitoring and tracing: fs debug, fs memdump,
fs messages, fs minidump, fs monitor, fs rxstatpeer, fs rxstatproc,
and fs trace.
· A command to administer the Cache Manager's interaction with other
file systems: fs exportafs.
· Commands to obtain help: fs apropos and fs help.
The Cache Manager and the fs commands use and maintain the following
configuration files:
/usr/vice/etc/CellServDB
Lists the database server machines in the local cell and any
foreign cell to which the administrator wishes to enable AFS access
for users working on the machine. The database server machines run
the Authentication, Backup, Protection and Volume Location (VL)
Server processes, which maintain databases of administrative
information. For users to access a cell, its "root.cell" volume
must also be mounted in the local cell's AFS file tree.
/usr/vice/etc/ThisCell
Defines the machine's cell membership with respect to the AFS
command suites and Cache Manager access to AFS data.
/usr/vice/etc/cacheinfo
Defines configuration parameters for the cache, including its size
and whether it is in memory or on disk.
In addition, the Cache Manager automatically creates files on the cache
partition (by default, /usr/vice/cache for caching and tracking files
fetched from file server machines.
For more details, see the reference page for each file.
OPTIONS
The following flag is available on every command in the fs suite. The
reference page for each command also lists it, but it is described here
in greater detail.
-help
Prints a command's online help message on the standard output
stream. Do not combine this flag with any of the command's other
options; when it is provided, the command interpreter ignores all
other options, and only prints the help message.
PRIVILEGE REQUIRED
The privileges required for fs commands vary more than for other
command suites. Pay special attention to the PRIVILEGE REQUIRED section
of each command description.
The various types of necessary privilege include:
· Having permissions on a directory's ACL. For example, creating and
removing mount points requires "a" (administer), "i" (insert), and
"d" (delete) permissions on the ACL of the directory in which the
mount point resides.
· Being logged onto the machine as the local superuser "root". This
is necessary when issuing commands that affect Cache Manager
configuration.
· Belonging to the system:administrators group in the Protection
Database.
· No privilege. Many fs commands simply list information.
