32 The B<vos listvol> command formats and displays the following information
33 from the volume header of each specified volume: volume name, volume ID,
34 volume type, size, and status at the server. The actual information
35 displayed depends on the combination of arguments supplied when the
36 command is issued. To display volume header information for various
37 numbers of volumes, combine the command's arguments as indicated:
43 For every volume on a file server machine, specify the machine's name with
44 the B<-server> argument.
48 For every volume at a particular site, combine the B<-server> argument
49 with the B<-partition> argument.
53 To display the Volume Location Database (VLDB) entry for one or more
54 volumes, use the B<vos listvldb> command. To display both the VLDB entry
55 and the volume header for a single volume, use the B<vos examine> command.
61 =item B<-server> <I<server name>>
63 Identifies the file server machine that houses volumes for which to
64 display the header. Provide the machine's IP address or its host name
65 (either fully qualified or using an unambiguous abbreviation). For
66 details, see L<vos(1)>.
68 This argument can be combined with the B<-partition> argument, as well as
69 the B<-fast>, B<-long>, or B<-extended> flag.
71 =item B<-partition> <I<partition name>>
73 Identifies the partition (on the file server machine specified by the
74 B<-server> argument) that houses volumes for which to display the
75 header. Provide the partition's complete name with preceding slash (for
76 example, F</vicepa>) or use one of the three acceptable abbreviated
77 forms. For details, see L<vos(1)>.
81 Displays only the volume ID numbers of volumes stored at the site
82 specified by the B<-server>, and optionally B<-partition>, argument. Do
83 not combine this flag with the B<-extended> flag.
87 Displays more detailed information about each volume stored at the site
88 specified by the B<-server>, and optionally B<-partition>, argument. The
89 information includes the volume IDs of all three volume types associated
90 with the volume, and the read/write volume's quota, creation date and
95 Suppresses the lines that summarize the number of volumes listed and their
96 status, which otherwise appear at the beginning and end of the output when
97 the output includes more than one volume.
101 Displays extensive statistics about access patterns for each volume stored
102 at the site specified by the B<-server>, and optionally B<-partition>,
103 argument. The statistics include the number of reads and writes to files
104 in the volume, and how recently files and directories have been updated by
105 their owners or other users. Do not combine this flag with the B<-fast>
110 Show information in a format suitable for machine parsing.
112 =include fragments/vos-common.pod
118 The output is ordered alphabetically by volume name and by default
119 provides the following information on a single line for each volume:
133 Type (the flag is C<RW> for read/write, C<RO> for read-only, C<BK> for
138 Size in kilobytes (C<1024> equals a megabyte)
142 Number of files in the volume, if the B<-extended> flag is provided
146 Status on the file server machine, which is one of the following:
152 The volume is completely accessible to Cache Managers.
156 The volume is not accessible to Cache Managers, but does not seem to be
157 corrupted. This status appears while a volume is being dumped, for
160 =item Off-line**needs salvage**
162 The volume is not accessible to Cache Managers, because it seems to be
163 corrupted. Use the B<bos salvage> or B<salvager> command to repair the
170 If the following message appears instead of the previously listed
171 information, it indicates that a volume is not accessible to Cache
172 Managers or the B<vos> command interpreter, for example because a clone is
175 **** Volume <volume_ID> is busy ****
177 If the following message appears instead of the previously listed
178 information, it indicates that the File Server is unable to attach the
179 volume, perhaps because it is seriously corrupted. The F<FileLog> and
180 F<VolserLog> log files in the F</usr/afs/logs> directory on the file
181 server machine possibly provide additional information; use the B<bos
182 getlog> command to display them.
184 **** Could not attach volume <volume_ID> ****
186 The information about individual volumes is bracketed by summary
187 lines. The first line of output specifies the number of volumes in the
188 listing. The last line of output summarizes the number of volumes that are
189 online, offline, and busy. These lines do not appear if the B<-quiet> flag
192 If the B<-fast> flag is added, the output displays only the volume ID
193 number of each volume, arranged in increasing numerical order. The final
194 line (which summarizes the number of online, offline, and busy volumes) is
197 If the B<-long> flag is included, the output for each volume includes all
198 of the information in the default listing plus the following. Each item in
199 this list corresponds to a separate line of output:
205 The file server machine and partition that house the volume, as determined
206 by the command interpreter as the command runs, rather than derived from the
207 VLDB or the volume header.
211 The volume ID numbers associated with the various versions of the volume:
212 read/write (C<RWrite>), read-only (C<ROnly>), backup (C<Backup>), and
213 ReleaseClone (C<RClone>). One of them matches the volume ID number that
214 appears on the first line of the volume's output. If the value in the
215 C<RWrite>, C<ROnly>, or C<Backup> field is C<0> (zero), there is no volume
216 of that type. If there is currently no ReleaseClone, the C<RClone> field
217 does not appear at all.
221 The maximum space quota allotted to the read/write copy of the volume,
222 expressed in kilobyte blocks in the C<MaxQuota> field.
226 The date and time the volume was created, in the C<Creation> field. If the
227 volume has been restored with the B<backup diskrestore>, B<backup
228 volrestore>, or B<vos restore> command, this is the restore time.
232 The date and time when the contents of the volume last changed, in the
233 C<Last Update> field. For read-only and backup volumes, it matches the
234 timestamp in the C<Creation> field.
238 The number of times the volume has been accessed for a fetch or store
239 operation since the later of the two following times:
245 12:00 a.m. on the day the command is issued
249 The last time the volume changed location
255 If the B<-extended> flag is included, the output for each volume includes
256 all of the information reported with the B<-long> flag, plus two tables of
263 The table labeled C<Raw Read/Write Stats> table summarizes the number of
264 times the volume has been accessed for reading or writing.
268 The table labeled C<Writes Affecting Authorship> table contains
269 information on writes made to files and directories in the specified
276 The following example shows the output for the F</vicepb> partition on the
277 file server machine C<fs2.example.com> when no flags are provided:
