       fs - Introduction to the fs command suite


       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 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:

           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.

           Defines the machine’s cell membership with respect to the AFS
           command suites and Cache Manager access to AFS data.

           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.


       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.

           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.


       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

       ·   Belonging to the system:administrators group in the Protection

       ·   No privilege. Many fs commands simply list information.
