NAME

  quotacheck - Checks file system quota	consistency

SYNOPSIS

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

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

OPTIONS

  -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 fol-
      lows:

      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 option is	only valid
	      when used	with the -a option.

  -u  Checks user quotas only.

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

OPERANDS

  filesystem
      Specifies	one or more file systems.  Specify any file system by enter-
      ing 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.


DESCRIPTION

  The quotacheck command examines each of the specified	file systems, build-
  ing 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 option to	specify	that only group	quotas be checked;
  use the -u option to specify that only user quotas be	checked.

  The quotacheck command does not display activity information while checking
  file systems.	Use the	-v option to report inconsistencies found or pro-
  cedures 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.
