If the 102.Dq Dv dqb_btime 103or 104.Dq Dv dbq_itime 105fields are non-zero, they are used to indicate the grace period on 106that file system for users who have exceeded their soft limit. 107These times can be set by 108.Xr edquota 8 109with the 110.Fl t 111flag. 112If no explicit grace period has been set with 113.Xr edquota 8 , 114then the default value of 7 days will be used. 115The default values are defined by 116.Dv MAX_DQ_TIME 117and 118.Dv MAX_IQ_TIME 119in 120.In ufs/ufs/quota.h . 121.Sh SEE ALSO 122.Xr quota 1 , 123.Xr quotactl 2 , 124.Xr fstab 5 , 125.Xr edquota 8 , 126.Xr quotacheck 8 , 127.Xr quotaoff 8 , 128.Xr quotaon 8 , 129.Xr repquota 8 130
