In Progress

The Zettabyte File System (ZFS) is a combined file system and logical volume manager designed to protect against data corruption and support high storage capacities.

The Foundation is sponsoring Matthew Ahrens to develop a “RAID-Z Expansion” feature. This will allow adding an extra disk to an existing RAID-Z group, allowing the expansion from a 4-wide RAID-Z1 group into a 5-wide RAID-Z1 group.
