Seagate’s Shingled Magnetic Recording Friendly File System (SMRFFS) is a effort to enable SMR use in Linux systems by taking advantage of the new zoned block device interfaces standards. Current developmental work focuses on ext4, with xfs and others to follow as SMR drives begin to permeate the market. Changes in ext4 includes modifications that respect the primary rule introduced by SMR: forward-write preferred. We demonstrate taking the T10/13 specs and aligning them in the legacy File System. This reduces the time for market convergence and the continued use of legacy software on upgraded legacy filesystems with new SMR drives. By transforming ext4 into a Host Aware SMR Friendly File System, we leverage the reliability record and performance of ext4 with a new generation of hardware.
