3 fs - Introduction to the fs command suite
7 The commands in the B<fs> command suite constitute the main administrative
8 interface to the Cache Manager on an AFS client machine, which is
9 responsible for fetching AFS data from file server machines on behalf of
10 applications running on the client machine.
12 There are several categories of commands in the B<fs> command suite:
18 Commands to set and report how the Cache Manager interacts with server

28 L<B<fs setserverprefs>|fs_setserverprefs(1)>,
29 L<B<fs sysname>|fs_sysname(1)>,
30 L<B<fs uuid>|fs_uuid(1)>,
31 and L<B<fs wscell>|fs_wscell(1)>.
35 Commands to administer access control lists (ACLs):

39 L<B<fs listacl>|fs_listacl(1)>,
40 and L<B<fs setacl>|fs_setacl(1)>.
44 Commands to administer server machines, volumes or partitions that house a
45 given file or directory:
46 L<B<fs diskfree>|fs_diskfree(1)>,
47 L<B<fs examine>|fs_examine(1)>,
48 L<B<fs getfid>|fs_getfid(1)>,
49 L<B<fs listquota>|fs_listquota(1)>,
50 L<B<fs quota>|fs_quota(1)>,
51 L<B<fs setquota>|fs_setquota(1)>,
52 L<B<fs setvol>|fs_setvol(1)>,
53 L<B<fs whereis>|fs_whereis(1)>,
54 and L<B<fs whichcell>|fs_whichcell(1)>.
58 Commands to administer the local client cache and related information:
59 L<B<fs checkvolumes>|fs_checkvolumes(1)>,
60 L<B<fs cscpolicy>|fs_cscpolicy(1)>,
61 L<B<fs flush>|fs_flush(1)>,
62 L<B<fs flushall>|fs_flushall(1)>,
63 L<B<fs flushvolume>|fs_flushvolume(1)>,
64 L<B<fs getcacheparms>|fs_getcacheparms(1)>,
65 L<B<fs listaliases>|fs_listaliases(1)>,
66 L<B<fs newalias>|fs_newalias(1)>,
67 and L<B<fs setcachesize>|fs_setcachesize(1)>.
71 Commands to administer volume mount points:
72 L<B<fs lsmount>|fs_lsmount(1)>,
73 L<B<fs mkmount>|fs_mkmount(1)>,
74 and L<B<fs rmmount>|fs_rmmount(1)>.
78 Commands to control monitoring and tracing:
79 L<B<fs debug>|fs_debug(1)>,
80 L<B<fs memdump>|fs_memdump(1)>,
81 and L<B<fs messages>|fs_messages(1)>.
85 A command to administer the Cache Manager's interaction with other
87 L<B<fs exportafs>|fs_exportafs(1)>.
91 Commands to obtain help:
92 L<B<fs apropos>|fs_apropos(1)>
93 and L<B<fs help>|fs_help(1)>.
97 The Cache Manager and the fs commands use and maintain the following
102 =item F</usr/vice/etc/CellServDB>
104 Lists the database server machines in the local cell and any foreign cell
105 to which the administrator wishes to enable AFS access for users working
106 on the machine. The database server machines run the Authentication,
107 Backup, Protection and Volume Location (VL) Server processes, which
108 maintain databases of administrative information. For users to access a
109 cell, its C<root.cell> volume must also be mounted in the local cell's AFS
112 =item F</usr/vice/etc/ThisCell>
114 Defines the machine's cell membership with respect to the AFS command
115 suites and Cache Manager access to AFS data.
117 =item F</usr/vice/etc/cacheinfo>
119 Defines configuration parameters for the cache, including its size and
120 whether it is in memory or on disk.
124 In addition, the Cache Manager automatically creates files on the cache
125 partition (by default, F</usr/vice/cache> for caching and tracking files
126 fetched from file server machines.
128 For more details, see the reference page for each file.
132 The following flag is available on every command in the fs suite. The
133 reference page for each command also lists it, but it is described here in
140 Prints a command's online help message on the standard output stream. Do
141 not combine this flag with any of the command's other options; when it is
142 provided, the command interpreter ignores all other options, and only
143 prints the help message.
147 =head1 PRIVILEGE REQUIRED
149 The privileges required for fs commands vary more than for other command
150 suites. Pay special attention to the PRIVILEGE REQUIRED section of each
153 The various types of necessary privilege include:
159 Having permissions on a directory's ACL. For example, creating and
160 removing mount points requires C<a> (administer), C<i> (insert), and C<d>
161 (delete) permissions on the ACL of the directory in which the mount point
166 Being logged onto the machine as the local superuser C<root>. This is
167 necessary when issuing commands that affect Cache Manager configuration.
171 Belonging to the system:administrators group in the Protection Database.
175 No privilege. Many B<fs> commands simply list information.
