Abstract:
Presented herein are methods, non-transitory computer readable media, and devices for selectively limiting the amount of data in a file system, which include: determining a reparity bit value for a write disk block range, wherein the reparity bit is configured to track a number of writes in progress to a stripe range; determining the reparity bit value; updating a threshold written disk block number as a highest disk block number of the reparity bit value; and initiating a RAID operation until it reaches the threshold written disk block number, wherein the threshold written disk block number comprises a maximum written disk block number representing the last disk block number written.
