QUOTACHECK(8) FreeBSD System Manager's Manual QUOTACHECK(8)
NAME
quotacheck - file system quota consistency checker
SYNOPSIS
quotacheck [-guv] [-c 32 | 64] [-l maxrun] -a
quotacheck [-guv] [-c 32 | 64] filesystem ...
DESCRIPTION
The quotacheck utility examines each file system, builds a table of
current disk usage, and compares this table against that recorded 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 latter only occurs if an active file
system is checked). By default both user and group quotas are checked.
The following options are available:
-a If supplied in place of any file system names, quotacheck will
check all the file systems indicated in /etc/fstab to be read-
write with disk quotas. By default only the types of quotas
listed in /etc/fstab are checked.
-c 32 | 64
Before performing its checks, quotacheck will convert the quota
file to the specified word size. A conversion size of 64 is
given to request conversion to the new 64-bit quota file format.
A conversion size of 32 is given to request conversion back to
the old 32-bit quota file format. The original quota file is
left unchanged and moved aside with an underscore and its format
size plus a .orig extension added to its name. Thus, the
original 32-bit quota.user quota file converted to the 64-bit
format quota file will be renamed to quota.user_32.orig.
-g Only group quotas listed in /etc/fstab are to be checked.
-l maxrun
Specifies the maximum number of concurrent file systems to check
in parallel. If this option is omitted, or if maxrun is zero,
parallel passes are run as per fsck(8). This option is
deprecated and parallel passes are always run as per fsck(8).
-u Only user quotas listed in /etc/fstab are to be checked.
-v Report discrepancies between the calculated and recorded disk
quotas and other additional diagnostic messages.
Specifying both -g and -u is equivalent to the default. Parallel passes
are run on the file systems required, using the pass numbers in
/etc/fstab in an identical fashion to fsck(8).
Normally, quotacheck operates silently.
The quotacheck utility expects each file system to be checked to have a
quota files named quota.user and quota.group which are located at the
root of the associated file system. These defaults may be overridden in
/etc/fstab. If a file is not present, quotacheck will create it. These
files should be edited with the edquota(8) utility.
The quotacheck utility accesses the raw device in calculating the actual
disk usage for each user. Thus, the file systems checked should be
quiescent while quotacheck is running.
FILES
quota.user at the file system root with user quotas
quota.group at the file system root with group quotas
/etc/fstab default file systems

HISTORY
The quotacheck utility appeared in 4.2BSD.
BUGS
The quota system will ignore UIDs or GIDs that would be negative when
evaluated as a signed value. Typically those types of ids can appear in
the file system from NFS mounts or archive files from other operating
systems. Extremely large UIDs or GIDs will cause quotacheck to run for
an unreasonable amount of time and also produce extremely large quota
data files.
