Evaluation of Filesystems for Shingled Drives - Hannes Reinecke, SUSE

Shingled drives impose some limitations on the I/O patterns. Especially the write path requires a strict sequential ordering. Normally filesystems or the block layer are not imposing any ordering requirements, so it'll depend on the filesystem implementation if the ordering can be guaranteed. In this presentation I'll evaluate current general-purpose filesystems (btrfs, ext4, and xfs) and a dedicated filesystem (nilfs) for this ordering guarantee and hence their suitability for shingled drives. Additionally I'll present strategies for deploying filesystems on shingled drives.
