+{{site.data.alerts.tip}}In GPFS there is a concept called <b>GraceTime</b>. Filesystems have a block (amount of data) and file (number of files) quota. 
+This quota contains a soft and hard limits. Once the soft limit is reached, users can keep writing up to their hard limit quota during the <b>grace period</b>.
+Once <b>GraceTime</b> or hard limit are reached, users will be unable to write and will need remove data below the soft limit (or ask for a quota increase
+when this is possible, see below table).
