quotacheck - Checks file system quota consistency
/usr/sbin/quotacheck [-guv] filesystem...
/usr/sbin/quotacheck -a [-guv] [-l number] [-t [no]type]
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. Checks group quotas only. Specifies the maximum
number of parallel quotacheck processes to run at one
time. Specifies the file system type. The supported file
systems are as follows: Advanced File System (AdvFS) 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. Checks user quotas only.
Reports discrepancies between the calculated and
recorded disk quotas.
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.
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.
The term file system represents either a UFS file system
or an AdvFS fileset.
You must be the root user to run the quotacheck command.
Specifies the command path Contains user quotas for fileset
Contains group quotas for fileset Contains file system
names and locations
