NAME    [Toc]    [Back]

     quotacheck	- EFS filesystem quota consistency checker

SYNOPSIS    [Toc]    [Back]

     /usr/etc/quotacheck [ -v ]	[ -p ] filesystem ...
     /usr/etc/quotacheck [ -v ]	[ -p ] -a
     /usr/etc/quotacheck [ -v ]	-n nusers filesystem ...
     /usr/etc/quotacheck [ -v ]	-n nusers -a

DESCRIPTION    [Toc]    [Back]

     quotacheck	examines local EFS filesystems,	builds a table of current disk
     usage, and	compares this table against that stored	in the disk quota file
     for the filesystem.  If any inconsistencies are detected, both the	quotas
     file and the current system copy of the incorrect quotas are updated (the
     latter only occurs	if quotas has been enabled for the filesystem).	 The
     filesystem	has to be mounted for quotacheck to be able to operate on it.
     quotacheck	ignores	XFS filesystems	since the XFS quota system is
     journalled	and therefore inherently consistent.

     If	the -a flag is supplied	in place of any	filesystem names, quotacheck
     checks all	the local filesystems indicated	in /etc/fstab to be read-write
     with disk quotas.

     Normally quotacheck operates silently.  If	the -v option is supplied,
     quotacheck	indicates the disk quotas for each user	whose quota
     information was modified.

     If	the -p flag is supplied	then parallel passes are run on	the
     filesystems required, using the pass numbers in /etc/fstab	in an
     identical fashion to fsck(1M).

     quotacheck	expects	each filesystem	to be checked to have a	quota file
     with the name quotas in the root directory.  If none is present,
     quotacheck	ignores	the filesystem.

     The quotas	file has an index followed by the users' quota information.
     If	while adding users with	the help of the	edquota(1M) command, there is
     no	more space left	in the index, the superuser can	increase the index
     size with the -n option to	permit the addition of more users to the
     quotas file.  nusers is the new number of users for whom sufficient index
     size should be allocated.	The default index size allows quotas for 2048
     users.  It	is not possible	to shrink the index size.  It is advisable to
     remount the filesystem after using	this option.

     quotacheck	is normally run	at boot	time from the /etc/rc2.d directory,
     see rc2(1M).

     quotacheck	accesses the raw device	in calculating the actual disk usage
     for each user.  Thus, the filesystems checked should be quiescent while
     quotacheck	is running.

EXAMPLES    [Toc]    [Back]

	  quotacheck -v	-n 3000	/usr

     Increases the quotas file index size to support 3000 users	(up from the
     default of	2048) for the /usr filesystem.
