48: .SH DESCRIPTION
49: .I Quotacheck
50: examines each filesystem,
51: builds a table of current disk usage,
52: and compares this table against that recorded
53: in the disk quota file for the filesystem.
54: If any inconsistencies are detected, both the
55: quota file and the current system copy of the
56: incorrect quotas are updated (the latter only
57: occurs if an active filesystem is checked).
58: By default both user and group quotas are checked.
59: The optional \fI-g\fP flag specifies that only group quotas should be checked.
60: The optional \fI-u\fP flag specifies that only user quotas should be checked.
61: Specifying both \fI-g\fP and \fI-u\fP is equivalent to the default.
62: .PP
63: If the
64: .B \-a
65: flag is supplied in place of any filesystem names,
66: .I quotacheck
67: will check all the filesystems indicated in
68: .I /etc/fstab
69: to be read-write with disk quotas.
70: By default only the types of quotas listed in
71: .I /etc/fstab
72: are checked.
73: The optional \fI-g\fP flag specifies that only group quotas listed in
74: .I /etc/fstab
75: should be checked.
76: The optional \fI-u\fP flag specifies that only user quotas listed in
77: .I /etc/fstab
78: should be checked.
79: Specifying both \fI-g\fP and \fI-u\fP is equivalent to the default.
80: Parallel passes are run on the filesystems required,
81: using the pass numbers in
82: .I /etc/fstab
83: in an identical fashion to
84: .IR fsck (8).
85: .PP
86: Normally
87: .I quotacheck
88: operates silently.
89: If the
90: .B \-v
91: option is supplied,
92: .I quotacheck
93: will report discrepancies between the
94: calculated and recorded disk quotas.
95: .PP
96: .I Quotacheck
97: expects each filesystem to be checked to have a
98: quota files named
99: .I quota.user
100: and
101: .I quota.group
102: which are located at the root of the associated file system.
103: These defaults may be overridden in
104: .I /etc/fstab .
105: If a file is not present,
106: .I quotacheck
107: will create it.
108: .PP
109: .I Quotacheck
110: is normally run at boot time from the
111: .I /etc/rc.local
112: file, see
113: .IR rc (8),
114: before enabling disk quotas with
115: .IR quotaon (8).
116: .PP
117: .I Quotacheck
118: accesses the raw device in calculating the actual
119: disk usage for each user.
120: Thus, the filesystems
121: checked should be quiescent while
122: .I quotacheck
123: is running.
