quotacheck(8)
NAME
  quotacheck - Checks file system quota consistency

SYNOPSIS
  /usr/sbin/quotacheck [-guv] filesystem ...

  /usr/sbin/quotacheck -a [-guv] [-l number] [-t [no]type]

PARAMETERS
  filesystem
	    Specifies one or more file systems.	 Specify any file system by
	    entering its full path name.  The full path name is the file
	    system's mount point in the /etc/fstab file.  You can also
	    specify a UFS file system by entering the name of its device
	    special file.  For example:	 /dev/disk/dsk3c.
	    You can also specify an AdvFS fileset by entering the name of the
	    file domain, a pound sign (#), and the name of the fileset.	 For
	    example: root_domain#root.

FLAGS
  -a	    Checks all UFS and AdvFS file systems identified in the
	    /etc/fstab file as read/write with userquota and/or groupquota
	    options specified, and a pass number of 1 or greater.  If -t
	    option is specified, only the file systems of the specified type
	    will be checked.  Alternatively, if type is prefixed with no,
	    then the valid file systems in the /etc/fstab file that do not
	    have that type will be checked.

  -g	    Checks group quotas only.

  -l number Specifies the maximum number of parallel quotacheck processes to
	    run at one time.

  -t   [no]type
	    Specifies the file system type.  The supported file systems are
	    as follows

	    advfs
	      Advanced File System (AdvFS)

	    ufs
	      UNIX File System (UFS)
  See fstab(4) for a description of file system types.	If the no prefix is
  used, all of the above file types except the one specified are checked.
  Note that the -t flag is only valid when used with the -a flag.

  -u	    Checks user quotas only.

  -v	    Reports discrepancies between the calculated and recorded disk
	    quotas.

DESCRIPTION
  The  quotacheck command examines each of the specified file systems,
  building a table of current disk usage.  It then compares this table
  against the table stored in the disk quota file for the file system.	If
  any inconsistencies are detected, both the quota file and the current
  system copy of the incorrect quotas are updated.

  The quotacheck -a command runs parallel passes on file systems using the
  number specified in the /etc/fstab pass number field.	 The command only
  checks file systems with pass number 1 or higher in the fsck field.  A file
  system with no pass number is not checked.

  For both UFS file systems and AdvFS filesets, you should assign the root
  file system a pass number of 1, and a value of 2 or higher to other file
  systems.  See fstab(4) for more information.

  The quotacheck command checks only file systems that are mounted.  UFS file
  systems must also have  userquota and/or groupquota options specified in
  the /etc/fstab file.	The userquota and groupquota options are only needed
  for AdvFS file systems if quotas are actually going to be enforced or if
  they are to be selected with the -a option.

  The quotacheck command must be run by a user with superuser authority.

  By default, both user and group quotas listed in the /etc/fstab file are
  checked.  Use the -g flag to specify that only group quotas be checked; use
  the -u flag to specify that only user quotas be checked.

  The quotacheck command does not display activity information while checking
  file systems. Use the -v flag to report inconsistencies found or procedures
  performed by the quotacheck command.

  The file systems to be checked should be quiescent while the quotacheck
  command is running.

NOTES
  The term file system represents either a UFS file system or an AdvFS
  fileset.

RESTRICTION
  You must be the root user to use the quotacheck command.

FILES
  /usr/sbin/quotacheck
	    Specifies the command path

	    Contains user quotas for fileset

  [fileset_root]/quota.group
	    Contains group quotas for fileset

  /etc/fstab
