Linux in a Nutshell, 6th Edition

Name

quotacheck

Synopsis

quotacheck [options] [filesystems]

System administration command. Audit and correct quota information by building a table of current disk usage and comparing it to the recorded usage in both the kernel and the quota files. quotacheck will update quota information when possible and prompt the user if it requires input. Most systems that support quotas run this command at system startup. To prevent damage to filesystems or loss of quota data, turn off quotas with quotaoff and umount the system. quotacheck will attempt to remount any mounted filesystem as read-only before scanning.
