DESCRIPTION

16       quotacheck  examines  each  mounted  ufs file system, builds a table of
17       current disk usage, and compares this  table  against  the  information
18       stored in the file system's disk quota file. If any inconsistencies are
19       detected, both the quota file and the current system copy of the incor‐
20       rect quotas are updated.
21
22
23       filesystem  is either a file system mount point or the block device  on
24       which the file system resides.
25
26
27       quotacheck expects each file system to be checked to have a quota  file
28       named quotas in the root directory. If none is present, quotacheck will
29       not check the file system.
30
31
32       quotacheck accesses the character special  device  in  calculating  the
33       actual  disk  usage  for  each  user.  Thus,  the file systems that are
34       checked should be quiescent while quotacheck is running.

OPTIONS

37       The following options are supported:
38
39       -a    Check the file systems which /etc/mnttab indicates are  ufs  file
40             systems.   These  file  systems  must be read-write mounted  with
41             disk quotas enabled, and have an rq entry in the mntopts field in
42             /etc/vfstab.
43
44
45       -f    Force check on file systems with logging enabled. Use in combina‐
46             tion with the -p option.
47
48
49       -p    Check quotas of file systems in parallel. For file  systems  with
50             logging  enabled,  no  check is performed unless the -f option is
51             also specified.
52
53
54       -v    Indicate the calculated disk quotas for each user on a particular
55             file  system. quotacheck normally reports only those quotas modi‐
56             fied.
