NAME
quotacheck - filesystem quota consistency checker SYNOPSIS
quotacheck [ -v ] filesystem ... quotacheck [ -v ] -a DESCRIPTION
Quotacheck examines each filesystem, builds a table of current disk usage, and compares this table against that recorded in the disk quota file for the filesystem. If any inconsistencies are detected, both the quota file and the current system copy of the incorrect quotas are updated (the latter only occurs if an active filesystem is checked). Available options: -a If the -a flag is supplied in place of any filesystem names, quotacheck will check all the filesystems indicated in /etc/fstab to be read-write with disk quotas. -v quotacheck reports discrepancies between the calculated and recorded disk quotas. Parallel passes are run on the filesystems required, using the pass numbers in /etc/fstab in an identical fashion to fsck(8). Normally quotacheck operates silently. Quotacheck expects each filesystem to be checked to have a quota files named quotas located at the root of the associated file system. These defaults may be overridden in /etc/fstab. If a file is not present, quotacheck will create it. Quotacheck is normally run at boot time from the /etc/rc.local file, see rc(8), before enabling disk quotas with quotaon(8). Quotacheck accesses the raw device in calculating the actual disk usage for each user. Thus, the filesystems checked should be quiescent while quotacheck is running. FILES
quotas at the filesystem root /etc/fstab default filesystems BUGS
The quotas file may be named arbitrarily but must reside in the filesystem for which it contains quota information. Quotacheck will give the error: %s dev (0x%x) mismatch %s (0x%x) if the quotas file is not in the filesystem being checked. This restriction is enforced by the kernel but may be lifted in the future.

NAME
quotacheck -- filesystem quota consistency checker SYNOPSIS
quotacheck [-g] [-u] [-v] filesystem ... quotacheck [-g] [-u] [-v] -a DESCRIPTION
Quotacheck examines each filesystem, builds a table of current disk usage, and compares this table against that recorded in the disk quota file for the filesystem. If any inconsistencies are detected, both the quota file and the current system copy of the incorrect quotas are updated (the latter only occurs if an active filesystem is checked). By default both user and group quotas are checked. Available options: -a If the -a flag is supplied in place of any filesystem names, quotacheck will check all the read-write filesystems with an existing mount option file at its root. The mount option file specifies the types of quotas that are to be checked. -g Only group quotas are checked. The mount option file, .quota.ops.group, must exist at the root of the filesystem. -u Only user quotas are checked. The mount option file, .quota.ops.user, must exist at the root of the filesystem. -v quotacheck reports discrepancies between the calculated and recorded disk quotas. Specifying both -g and -u is equivalent to the default. Parallel passes are run on the filesystems required, in an identical fashion to fsck(8). Normally quotacheck operates silently. Quotacheck expects each filesystem being checked to have quota data files named .quota.user and/or .quota.group located at the filesystem root. If a binary data file is not present, quotacheck will create it. The default filename and root location cannot be overridden. Quotacheck is normally run at fsck time. Quotacheck accesses the raw device in calculating the actual disk usage for each user. Thus, the filesystems checked should be quiescent while quotacheck is running. FILES
Each of the following quota files is located at the root of the mounted filesystem. The mount option files are empty files whose existence indicates that quotas are to be enabled for that filesystem. The binary data files will be created by quotacheck, if they don't already exist. .quota.user data file containing user quotas .quota.group data file containing group quotas .quota.ops.user mount option file used to enable user quotas .quota.ops.group mount option file used to enable group quotas SEE ALSO
