QUOTACHECK(8) Maintenance Commands and Procedures QUOTACHECK(8)

NAME

quotacheck - ufs file system quota consistency checker

SYNOPSIS

quotacheck [-fp] [-v] filesystem...


quotacheck -a [-fpv]

DESCRIPTION

quotacheck examines each mounted ufs file system, builds a table of
current disk usage, and compares this table against the information
stored in the file system's disk quota file. If any inconsistencies
are detected, both the quota file and the current system copy of the
incorrect quotas are updated.


filesystem is either a file system mount point or the block device
on which the file system resides.


quotacheck expects each file system to be checked to have a quota
file named quotas in the root directory. If none is present,
quotacheck will not check the file system.


quotacheck accesses the character special device in calculating the
actual disk usage for each user. Thus, the file systems that are
checked should be quiescent while quotacheck is running.

OPTIONS

The following options are supported:

-a
Check the file systems which /etc/mnttab indicates are ufs file
systems. These file systems must be read-write mounted with
disk quotas enabled, and have an rq entry in the mntopts field
in /etc/vfstab.


-f
Force check on file systems with logging enabled. Use in
combination with the -p option.


-p
Check quotas of file systems in parallel. For file systems with
logging enabled, no check is performed unless the -f option is
also specified.


-v
Indicate the calculated disk quotas for each user on a
particular file system. quotacheck normally reports only those
quotas modified.

USAGE

See largefile(7) for the description of the behavior of quotacheck
when encountering files greater than or equal to 2 Gbyte ( 2^31
bytes).
