NAME

       volinfo - Produces detailed statistics about AFS volume headers

SYNOPSIS

       volinfo [-checkout] [-vnode] [-date] [-inode] [-itime]
           [-part <AFS partition name (default current partition)>+]
           [-volumeid <volume id>+] [-header] [-sizeonly]
           [-fixheader] [-saveinodes] [-orphaned] [-filenames] [-help]

DESCRIPTION

       The volinfo command displays detailed statistics about one or more volume headers and the
       partition that houses them. The command must be issued on a file server machine and by
       default produces output for every volume on every AFS server partition on the machine. To
       display output for the volumes on one partition only, include the -part argument. To
       display output for one volume only, include the -volumeid argument.

OPTIONS

       -checkout
           Checkout the specified volume from the running fileserver. This ensures that the
           fileserver or other processes will not be modifying volume metadata at the same time
           we are trying to read it, leading to invalid or incorrect results.

       -vnode
           Displays a table for each volume which lists the large (directory) and small (file)
           vnodes in it, in addition to the default output.

       -date
           When combined with the -vnode flag, adds the "ServerModTime" field to each vnode entry
           in the large vnode and small vnode tables, reporting its most recent modification
           time.

       -inode
           When combined with the -vnode flag, adds the "inode" field to each vnode entry in the
           large vnode and small vnode tables, reporting the associated inode number.

       -itime
           When combined with the -vnode flag, displays a change, modification, and access
           timestamp for each of the large vnode and small vnode tables.

       -part <partition name or id>+
           Specifies the partition that houses each volume for which to produce output. Use the
           format /vicepxx or xx, where xx is one or two lowercase letters. This argument can be
           omitted if the current working directory is the mount location for an AFS server
           partition. If it is not the mount location for an AFS server partition, the command
           produces output for every volume on all local AFS server partitions.

       -volumeid <volume id>+
           Specifies the ID number of one volume for which to produce output.  The -part argument
           must be provided along with this one unless the current working directory is the mount
           location for the AFS server partition that houses the volume.

       -header
           Displays statistics about the volume header of each volume, in addition to the default
           output.

       -sizeonly
           Displays a single line of output for each volume, reporting the size of various
           structures associated with it. The default output is suppressed and any flags that
           modify it (such as -vnode) are ignored.

       -fixheader
           Repairs damaged inodes in each volume if possible. If there are any, it reports the
           action it is taking to repair them. Otherwise, it produces no output in addition to
           the default output.

       -saveinodes
           Creates a file in the current working directory for each inode in each volume. Each
           file is called TmpInode.vnode_number and contains the inode's contents. The default
           output is suppressed and any flags that modify it (such as -vnode) are ignored.

       -orphaned
           Displays a large vnode and small vnode table for each volume, which lists only
           orphaned vnodes (vnodes that have no parent). If there are none, the tables are empty
           (only the headers appear).

       -filenames
           When combined with the -vnode flag, adds the full path and file name of the "namei"
           file which stores the vnode data to each vnode entry in the large vnode and small
           vnode tables. This option is only available on fileservers which use the "namei"
           storage format for storing data.

       -help
           Prints the online help for this command. All other valid options are ignored.

OUTPUT

       By default, the command produces several line of statistics for each volume. Adding other
       options produces or substitutes additional information as described in "OPTIONS".  The
       output is intended for debugging purposes and is meaningful to someone familiar with the
       internal structure of volume headers.

PRIVILEGE REQUIRED

       The issuer must be logged in as the local superuser "root".
