40 <P><STRONG>Description</STRONG>
41 <P>The <B>vos listvol</B> command formats and displays the following
42 information from the volume header of each specified volume: volume
43 name, volume ID, volume type, size, and status at the server. The
44 actual information displayed depends on the combination of arguments supplied
45 when the command is issued. To display volume header information for
46 various numbers of volumes, combine the command's arguments as
49 <P><LI>For every volume on a file server machine, specify the machine's name
50 with the <B>-server</B> argument.
51 <P><LI>For every volume at a particular site, combine the <B>-server</B>
52 argument with the <B>-partition</B> argument.
54 <P>To display the Volume Location Database (VLDB) entry for one or more
55 volumes, use the <B>vos listvldb</B> command. To display both the
56 VLDB entry and the volume header for a single volume, use the <B>vos
58 <P><STRONG>Options</STRONG>
61 </B><DD>Identifies the file server machine that houses volumes for which to
62 display the header. Provide the machine's IP address or its host
63 name (either fully qualified or using an unambiguous abbreviation). For
64 details, see the introductory reference page for the <B>vos</B> command
66 <P>This argument can be combined with the <B>-partition</B> argument, as
67 well as the <B>-fast</B>, <B>-long</B>, or <B>-extended</B>
70 </B><DD>Identifies the partition (on the file server machine specified by the
71 <B>-server</B> argument) that houses volumes for which to display the
72 header. Provide the partition's complete name with preceding slash
73 (for example, <B>/vicepa</B>) or use one of the three acceptable
74 abbreviated forms. For details, see the introductory reference page for
75 the <B>vos</B> command suite.
77 </B><DD>Displays only the volume ID numbers of volumes stored at the site
78 specified by the <B>-server</B>, and optionally <B>-partition</B>,
79 argument. Do not combine this flag with the <B>-extended</B>
82 </B><DD>Displays more detailed information about each volume stored at the site
83 specified by the <B>-server</B>, and optionally <B>-partition</B>,
84 argument. The information includes the volume IDs of all three volume
85 types associated with the volume, and the read/write volume's quota,
86 creation date and update date.
88 </B><DD>Suppresses the lines that summarize the number of volumes listed and their
89 status, which otherwise appear at the beginning and end of the output when the
90 output includes more than one volume.
92 </B><DD>Displays extensive statistics about access patterns for each volume stored
93 at the site specified by the <B>-server</B>, and optionally
94 <B>-partition</B>, argument. The statistics include the number of
95 reads and writes to files in the volume, and how recently files and
96 directories have been updated by their owners or other users. Do not
97 combine this flag with the <B>-fast</B> flag.
99 </B><DD>Names the cell in which to run the command. Do not combine this
100 argument with the <B>-localauth</B> flag. For more details, see the
101 introductory <B>vos</B> reference page.
103 </B><DD>Assigns the unprivileged identity <B>anonymous</B> to the
104 issuer. Do not combine this flag with the <B>-localauth</B>
105 flag. For more details, see the introductory <B>vos</B> reference
108 </B><DD>Constructs a server ticket using a key from the local
109 <B>/usr/afs/etc/KeyFile</B> file. The <B>vos</B> command
110 interpreter presents it to the Volume Server and Volume Location Server during
111 mutual authentication. Do not combine this flag with the
112 <B>-cell</B> argument or <B>-noauth</B> flag. For more details,
113 see the introductory <B>vos</B> reference page.
115 </B><DD>Produces on the standard output stream a detailed trace of the
116 command's execution. If this argument is omitted, only warnings
117 and error messages appear.
119 </B><DD>Prints the online help for this command. All other valid options
122 <P><STRONG>Output</STRONG>
123 <P>The output is ordered alphabetically by volume name and by default provides
124 the following information on a single line for each volume:
127 <P><LI>Volume ID number
128 <A NAME="IDX5740"></A>
129 <P><LI>Type (the flag is <TT>RW</TT> for read/write, <TT>RO</TT> for
130 read-only, <TT>BK</TT> for backup)
131 <P><LI>Size in kilobytes (<TT>1024</TT> equals a megabyte)
132 <P><LI>Number of files in the volume, if the <B>-extended</B> flag is
134 <A NAME="IDX5741"></A>
135 <P><LI>Status on the file server machine, which is one of the following:
137 <A NAME="IDX5742"></A>
138 <P><DT><B><TT>On-line</TT>
139 </B><DD>The volume is completely accessible to Cache Managers.
140 <A NAME="IDX5743"></A>
141 <P><DT><B><TT>Off-line</TT>
142 </B><DD>The volume is not accessible to Cache Managers, but does not seem to be
143 corrupted. This status appears while a volume is being dumped, for
145 <A NAME="IDX5744"></A>
146 <P><DT><B><TT>Off-line**needs salvage**</TT>
147 </B><DD>The volume is not accessible to Cache Managers, because it seems to be
148 corrupted. Use the <B>bos salvage</B> or <B>salvager</B>
149 command to repair the corruption.
152 <P>If the following message appears instead of the previously listed
153 information, it indicates that a volume is not accessible to Cache Managers or
154 the <B>vos</B> command interpreter, for example because a clone is being
156 <PRE> **** Volume <VAR>volume_ID</VAR> is busy ****
158 <P>If the following message appears instead of the previously listed
159 information, it indicates that the File Server is unable to attach the volume,
160 perhaps because it is seriously corrupted. The <B>FileLog</B> and
161 <B>VolserLog</B> log files in the <B>/usr/afs/logs</B> directory on
162 the file server machine possibly provide additional information; use the
163 <B>bos getlog</B> command to display them.
164 <PRE> **** Could not attach volume <VAR>volume_ID</VAR> ****
166 <P>The information about individual volumes is bracketed by summary
167 lines. The first line of output specifies the number of volumes in the
168 listing. The last line of output summarizes the number of volumes that
169 are online, offline, and busy. These lines do not appear if the
170 <B>-quiet</B> flag is used.
171 <P>If the <B>-fast</B> flag is added, the output displays only the volume
172 ID number of each volume, arranged in increasing numerical order. The
173 final line (which summarizes the number of online, offline, and busy volumes)
175 <P>If the <B>-long</B> flag is included, the output for each volume
176 includes all of the information in the default listing plus the
177 following. Each item in this list corresponds to a separate line of
180 <P><LI>The file server machine and partition that house the volume, as determined
181 by the command interpreter as the command runs, rather than derived from the
182 VLDB or the volume header.

194 of them matches the volume ID number that appears on the first line of the
195 volume's output. If the value in the <TT>RWrite</TT>,
196 <TT>ROnly</TT>, or <TT>Backup</TT> field is <TT>0</TT> (zero), there is
197 no volume of that type. If there is currently no ReleaseClone, the

208 command, this is the restore time.

223 <P>If the <B>-extended</B> flag is included, the output for each volume
224 includes all of the information reported with the <B>-long</B> flag, plus
225 two tables of statistics:
227 <P><LI>The table labeled <TT>Raw Read/Write Stats</TT> table summarizes the
228 number of times the volume has been accessed for reading or writing.
