3 fs - Introduction to the C<fs> command suite
7 The commands in the C<fs> command suite constitute the main
8 administrative interface to the Cache Manager on an AFS client
9 machine, which is responsible for fetching AFS data from file server
10 machines on behalf of applications running on the client machine.
12 There are several categories of commands in the C<fs> command suite:
18 Commands to set and report how the Cache Manager interacts with
19 server machines: C<fs checkservers>, C<fs getcellstatus>, C<fs
20 getserverprefs>, C<fs listcells>, C<fs newcell>, C<fs setcell>,
21 C<fs setserverprefs>, C<fs sysname>, and C<fs wscell>
25 Commands to administer access control lists (ACLs): C<fs cleanacl>,
26 C<fs copyacl>, C<fs listacl>, and C<fs setacl>
30 Commands to administer server machines, volumes or partitions that
31 house a given file or directory: C<fs diskfree>, C<fs examine>, C<fs
32 listquota>, C<fs quota>, C<fs setquota>, C<fs setvol>,
33 C<fs whereis>, and C<fs whichcell>
37 Commands to administer the local client cache and related
38 information: C<fs checkvolumes>, C<fs flush>, C<fs flushvolume>, C<fs
39 getcacheparms>, and C<fs setcachesize>
43 Commands to administer volume mount points: C<fs lsmount>, C<fs
44 mkmount>, and C<fs rmmount>
48 Commands to control monitoring and tracing: C<fs debug>, and C<fs
53 A command to administer the Cache Manager's interaction with other
54 file systems: C<fs exportafs>
58 Commands to obtain help: C<fs apropos> and C<fs help>
62 The Cache Manager and the C<fs> commands use and maintain the following
69 The B</usr/vice/etc/CellServDB> file lists the database server
70 machines in the local cell and any foreign cell to which the
71 administrator wishes to enable AFS access for users working on the
72 machine. The database server machines run the Authentication,
73 Backup, Protection and Volume Location (VL) Server processes,
74 which maintain databases of administrative information. For users
75 to access a cell, its B<root.cell> volume must also be mounted in the
76 local cell's AFS file tree.
80 The B</usr/vice/etc/ThisCell> file defines the machine's cell
81 membership with respect to the AFS command suites and Cache
82 Manager access to AFS data.
86 The B</usr/vice/etc/cacheinfo> file defines configuration parameters
87 for the cache, including its size and whether it is in memory or
92 In addition, the Cache Manager automatically creates files on the
93 cache partition (by default, B</usr/vice/cache> for caching and tracking
94 files fetched from file server machines.
96 For more details, see the reference page for each file.
100 The following flag is available on every command in the C<fs> suite. The
101 reference page for each command also lists it, but it is described
102 here in greater detail.
108 Prints a command's online help message on the standard output
109 stream. Do not combine this flag with any of the command's
110 other options; when it is provided, the command interpreter
111 ignores all other options, and only prints the help message.
115 =head1 PRIVILEGE REQUIRED
117 The privileges required for C<fs> commands vary more than for other
118 command suites. Pay special attention to the C<PRIVILEGE REQUIRED>
119 section of each command description.
121 The various types of necessary privilege include:
127 Having permissions on a directory's ACL. For example, creating and
128 removing mount points requires B<a> (B<administer>), B<i> (B<insert>), and B<d>
129 (B<delete>) permissions on the ACL of the directory in which the
134 Being logged onto the machine as the local superuser B<root>. This is
135 necessary when issuing commands that affect Cache Manager
140 Belonging to the B<system:administrators> group in the Protection
145 No privilege. Many C<fs> commands simply list information.
