NAME

       volinfo - Produces detailed statistics about AFS volume headers

SYNOPSIS

       volinfo [-online] [-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

       -online
           Is nonoperational.

       -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".
