volinfo(8)
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".
