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]

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
      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 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
      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.

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.

  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
  procedures performed by the quotacheck command.

  The file systems to be checked should be quiescent while the quotacheck
  command is running, and no files should be open on the mount point. It is
  recommended that system filesets /, /usr, /var be checked in single-user
  mode, due to possible system background activity on these filesets in
  multi-user mode.

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

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