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".
