Purpose
Displays information from the volume header and VLDB entry for a volume.
Synopsis
vos examine -id <volume name or ID> [-extended] [-cell <cell name>]
[-noauth] [-localauth] [-verbose] [-help]
vos e -i <volume name or ID> [-e] [-c <cell name>] [-n] [-l] [-v] [-h]
vos volinfo -i <volume name or ID> [-e] [-c <cell name>]
[-n] [-l] [-v] [-h]
vos v -i <volume name or ID> [-e] [-c <cell name>] [-n] [-l] [-v] [-h]
Description
The vos examine command formats and displays information from the Volume Location Database (VLDB) entry and the volume header of the volume specified by the -id argument.
To display the volume header only, use the vos listvol command. To display information from the VLDB only, use the vos listvldb command.
Options
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.
When the -extended flag is included, two tables appear next:
If the following message appears instead of the previously listed information, it indicates that a volume is not accessible to Cache Managers or the vos command interpreter, for example because a clone is being created.
**** Volume volume_ID is busy ****
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 FileLog and VolserLog log files in the /usr/afs/logs directory on the file server machine possibly provide additional information; use the bos getlog command to display them.
**** Could not attach volume volume_ID ****
Following a blank line, information from the VLDB entry appears. Each item in this list corresponds to a separate line in the output:
For further discussion of the New release and Old release flags, see the reference page for the vos release command.
Examples
The following example shows output for the ABC Corporation volume called usr with two read-only replication sites (this volume is mounted at the /afs/abc.com/usr directory). For the sake of illustration, the output shows the volume as locked.

Volume is currently LOCKED
The following example shows the output for the volume user.terry using the -extended flag. The volume has no read-only replication sites.
% vos examine -id user.terry -extended
