To display information from the VLDB only, use the \fBvos listvldb\fR command. .SH CAUTIONS .IX Header "CAUTIONS" Currently, the maximum quota for a volume is 2 terabytes (2^41 bytes). Note that this only affects the volume's quota; a volume may grow much larger if the volume quota is disabled. However, volumes over 2 terabytes in size may be impractical to move, and may have their size incorrectly reported by some tools, such as \fBfs_listquota\fR\|(1). .SH OPTIONS .IX Header "OPTIONS" .IP "\fB\-id\fR <\fIvolume name or ID\fR>" 4 .IX Item "-id " Specifies either the complete name or volume ID number of the volume, which can be read/write, read-only, or backup. .IP \fB\-extended\fR 4 .IX Item "-extended" Displays statistics about read and write operations on files and directories in the volume. .IP \fB\-format\fR 4 .IX Item "-format" Shows information in a format suitable for machine parsing. .IP "\fB\-cell\fR <\fIcell name\fR>" 4 .IX Item "-cell " Names the cell in which to run the command. Do not combine this argument with the \fB\-localauth\fR flag. For more details, see \fBvos\fR\|(1). .IP \fB\-noauth\fR 4 .IX Item "-noauth" Assigns the unprivileged identity \f(CW\*(C`anonymous\*(C'\fR to the issuer. Do not combine this flag with the \fB\-localauth\fR flag. For more details, see \&\fBvos\fR\|(1). .IP \fB\-localauth\fR 4 .IX Item "-localauth" Constructs a server ticket using a key from the local \&\fI/etc/openafs/server/KeyFile\fR file. The \fBvos\fR command interpreter presents it to the Volume Server and Volume Location Server during mutual authentication. Do not combine this flag with the \fB\-cell\fR argument or \&\fB\-noauth\fR flag. For more details, see \fBvos\fR\|(1). .IP \fB\-verbose\fR 4 .IX Item "-verbose" Produces on the standard output stream a detailed trace of the command's execution. If this argument is omitted, only warnings and error messages appear. .IP \fB\-encrypt\fR 4 .IX Item "-encrypt" Encrypts the command so that the operation's results are not transmitted across the network in clear text. This option is available in OpenAFS versions 1.4.11 or later and 1.5.60 or later. .IP \fB\-noresolve\fR 4 .IX Item "-noresolve" Shows all servers as IP addresses instead of the DNS name. This is very useful when the server address is registered as 127.0.0.1 or when dealing with multi-homed servers. This option is available in OpenAFS versions 1.4.8 or later and 1.5.35 or later. .IP "\fB\-config\fR <\fIconfiguration directory\fR>" 4 .IX Item "-config " Set the location of the configuration directory to be used. This defaults to \&\fI/etc/openafs\fR, except if \fB\-localauth\fR is specified, in which case the default is \fI/etc/openafs/server\fR. This option allows the use of alternative configuration locations for testing purposes. .IP \fB\-help\fR 4 .IX Item "-help" Prints the online help for this command. All other valid options are ignored. .SH OUTPUT .IX Header "OUTPUT" The first seven lines of the output show information from the volume header and the remaining lines come from the VLDB. Each item in the following list corresponds to a line of output derived from the volume header. .IP \(bu 4 Basic information about the specified volume (displayed on a single line): .RS 4 .IP \(bu 4 Name .IP \(bu 4 Volume ID number .IP \(bu 4 Type (the flag is \f(CW\*(C`RW\*(C'\fR for read/write, \f(CW\*(C`RO\*(C'\fR for read-only, \f(CW\*(C`BK\*(C'\fR for backup) .IP \(bu 4 Size in kilobytes (\f(CW1024\fR equals a megabyte) .IP \(bu 4 Number of files in the volume, if the \fB\-extended\fR flag is provided .IP \(bu 4 Status on the file server machine, which is one of the following: .RS 4 .IP On-line 4 .IX Item "On-line" The volume is completely accessible to Cache Managers. .IP Off-line 4 .IX Item "Off-line" The volume is not accessible to Cache Managers, but does not seem to be corrupted. This status appears while a volume is being dumped, for example. .IP "Off\-line**needs salvage**" 4 .IX Item "Off-line**needs salvage**" The volume is not accessible to Cache Managers, because it seems to be corrupted. Use the \fBbos salvage\fR or \fBsalvager\fR command to repair the corruption. .RE .RS 4 .RE .RE .RS 4 .RE .IP \(bu 4 The file server machine and partition that house the volume, as determined by the command interpreter as the command runs, rather than derived from the VLDB or the volume header. .IP \(bu 4 The volume ID numbers associated with the various versions of the volume: read/write (\f(CW\*(C`RWrite\*(C'\fR), read-only (\f(CW\*(C`ROnly\*(C'\fR), backup (\f(CW\*(C`Backup\*(C'\fR), and ReleaseClone (\f(CW\*(C`RClone\*(C'\fR). One of them matches the volume ID number that appears on the first line of the volume's output. If the value in the \&\f(CW\*(C`RWrite\*(C'\fR, \f(CW\*(C`ROnly\*(C'\fR, or \f(CW\*(C`Backup\*(C'\fR field is \f(CW0\fR (zero), there is no volume of that type. If there is currently no ReleaseClone, the \f(CW\*(C`RClone\*(C'\fR field does not appear at all. .IP \(bu 4 The maximum space quota allotted to the read/write copy of the volume, expressed in kilobyte blocks in the \f(CW\*(C`MaxQuota\*(C'\fR field. .IP \(bu 4 The date and time the volume was created, in the \f(CW\*(C`Creation\*(C'\fR field. If the volume has been restored with the \fBbackup diskrestore\fR, \fBbackup volrestore\fR, or \fBvos restore\fR command, this is the restore time. For a read-only volume, this is the last release time. .IP \(bu 4 The date and time this copy of this volume was created, in the \f(CW\*(C`Copy\*(C'\fR field. This is the time when the volume was created on this server and partition. For read-only volumes, it is not updated by a release (unlike the Creation date). The copy date is not stored in volume dumps. .IP \(bu 4 The date and time when the contents of the volume last changed, in the \&\f(CW\*(C`Last Update\*(C'\fR field. For read-only and backup volumes, it matches the timestamp in the \f(CW\*(C`Creation\*(C'\fR field. .IP \(bu 4 The number of times the volume has been accessed for a fetch or store operation since the later of the two following times: .RS 4 .IP \(bu 4 12:00 a.m. on the day the command is issued .IP \(bu 4 The last time the volume changed location .RE .RS 4 .RE .PP When the \fB\-extended\fR flag is included, two tables appear next: .IP \(bu 4 The table labeled \f(CW\*(C`Raw Read/Write Stats\*(C'\fR contains information on the number of reads (fetches) and writes (stores) made on the specified volume. .IP \(bu 4 The table labeled \f(CW\*(C`Writes Affecting Authorship\*(C'\fR contains information on writes made to files and directories in the specified volume. .PP If the following message appears instead of the previously listed information, it indicates that a volume is not accessible to Cache Managers or the \fBvos\fR command interpreter, for example because a clone is being created. .PP .Vb 1 \& **** Volume is busy **** .Ve .PP If the following message appears instead of the previously listed information, it indicates that the File Server is unable to attach the volume, perhaps because it is seriously corrupted. The \fIFileLog\fR and \&\fIVolserLog\fR log files in the \fI/var/log/openafs\fR directory on the file server machine possibly provide additional information; use the \fBbos getlog\fR command to display them. .PP .Vb 1 \& **** Could not attach volume **** .Ve .PP Following a blank line, information from the VLDB entry appears. Each item in this list corresponds to a separate line in the output: .IP \(bu 4 The base (read/write) volume name. The read-only and backup versions have the same name with a \f(CW\*(C`.readonly\*(C'\fR and \f(CW\*(C`.backup\*(C'\fR extension, respectively. .IP \(bu 4 The volume ID numbers allocated to the versions of the volume that actually exist, in fields labeled \f(CW\*(C`RWrite\*(C'\fR for the read/write, \f(CW\*(C`ROnly\*(C'\fR for the read-only, \f(CW\*(C`Backup\*(C'\fR for the backup, and \f(CW\*(C`RClone\*(C'\fR for the ReleaseClone. (If a field does not appear, the corresponding version of the volume does not exist.) The appearance of the \f(CW\*(C`RClone\*(C'\fR field normally indicates that a release operation did not complete successfully; the \&\f(CW\*(C`Old release\*(C'\fR and \f(CW\*(C`New release\*(C'\fR flags often also appear on one or more of the site definition lines described just following. .IP \(bu 4 The number of sites that house a read/write or read-only copy of the volume, following the string \f(CW\*(C`number of sites \->\*(C'\fR. .IP \(bu 4 A line for each site that houses a read/write or read-only copy of the volume, specifying the file server machine, partition, and type of volume (\f(CW\*(C`RW\*(C'\fR for read/write or \f(CW\*(C`RO\*(C'\fR for read-only). If a backup version exists, it is understood to share the read/write site. Several flags can appear with a site definition: .RS 4 .IP "Not released" 4 .IX Item "Not released" Indicates that the vos release command has not been issued since the \fBvos addsite\fR command was used to define the read-only site. .IP "Old release" 4 .IX Item "Old release" Indicates that a vos release command did not complete successfully, leaving the previous, obsolete version of the volume at this site. .IP "New release" 4 .IX Item "New release" Indicates that a vos release command did not complete successfully, but that this site did receive the correct new version of the volume. .RE .RS 4 .RE .IP \(bu 4 If the VLDB entry is locked, the string \f(CW\*(C`Volume is currently LOCKED\*(C'\fR, as well as (in OpenAFS 1.5.75 and later) one or more of the following strings: .RS 4 .IP "Volume is locked for a move operation" 4 .IX Item "Volume is locked for a move operation" Indicates that the volume was locked due to a \fBvos move\fR or a \fBvos convertROtoRW\fR command. .IP "Volume is locked for a release operation" 4 .IX Item "Volume is locked for a release operation" Indicates that the volume was locked due to a \fBvos release\fR command. .IP "Volume is locked for a backup operation" 4 .IX Item "Volume is locked for a backup operation" Indicates that the volume was locked due to a \fBvos backup\fR command. .IP "Volume is locked for a delete/misc operation" 4 .IX Item "Volume is locked for a delete/misc operation" Indicates that the volume was locked due to a \fBvos delentry\fR, \fBvos addsite\fR, \fBvos remsite\fR, \fBvos changeloc\fR, \fBvos syncvldb\fR, \fBvos syncserv\fR, \fBvos rename\fR, or \fBvos lock\fR command. .IP "Volume is locked for a dump/restore operation" 4 .IX Item "Volume is locked for a dump/restore operation" Indicates that the volume was locked due to a \fBvos dump\fR or \fBvos restore\fR command. .RE .RS 4 .RE .PP For further discussion of the \f(CW\*(C`New release\*(C'\fR and \f(CW\*(C`Old release\*(C'\fR flags, see \&\fBvos_release\fR\|(1). .SH EXAMPLES .IX Header "EXAMPLES" The following example shows output for the Example Corporation volume called \&\f(CW\*(C`usr\*(C'\fR with two read-only replication sites (this volume is mounted at the \&\fI/afs/example.com/usr\fR directory).
