4: quotacheck \- file system quota consistency checker
5: .SH SYNOPSIS
6: .B /etc/quotacheck
7: [
8: .B \-v
9: ]
10: filesystem...
11: .br
12: .B /etc/quotacheck

16: .B \-a
17: .SH DESCRIPTION
18: .I Quotacheck
19: examines each file system,
20: builds a table of current disc usage,
21: and compares this table against that stored
22: in the disc quota file for the file system.
23: If any inconsistencies are detected, both the
24: quota file and the current system copy of the
25: incorrect quotas are updated (the latter only
26: occurs if an active file system is checked).
27: .PP
28: If the
29: .B \-a
30: flag is supplied in place of any file system
31: names,
32: .I quotacheck
33: will check all the file systems indicated in
34: .I /etc/fstab
35: to be read-write with disc quotas.
36: .PP
37: Normally
38: .I quotacheck
39: reports only those quotas modified. If the
40: .B \-v
41: option is supplied,
42: .I quotacheck
43: will indicate the calculated disc quotas for each
44: user on a particular file system.
45: .PP
46: .I Quotacheck
47: expects each file system to be checked to have a
48: quota file named
49: .I quotas
50: in the root directory. If none is present,
51: .I quotacheck
52: will ignore the file system.
53: .PP
54: .I Quotacheck
55: is normally run at boot time from the
56: .I /etc/rc.local
57: file, see
58: .IR rc (8),
59: before enabling disc quotas with
60: .IR quotaon (8).
61: .PP
62: .I Quotacheck
63: accesses the raw device in calculating the actual
64: disc usage for each user. Thus, the file systems
65: checked should be quiescent while
66: .I quotacheck
67: is running.
