JBODs Aren't Actually Identical
- MIT's AI Lab shared JBOD horror stories showing identical models still varied in slot numbering and backplane layouts.
- Allan Jude and others found small manufacturing differences caused real operational surprises in their storage fleets.
AnyRaid Uses Tiles For Flexible VDEVs
- AnyRaid slices disks into small tiles and assembles stripes to use mixed drive sizes safely while avoiding co-locating stripe pieces on one disk.
- This design enables contracting and expanding VDEVs by moving tiles and includes a rebalance mode for near-full pools.
Rebalance After Adding Big Drives
- Use rebalance mode after adding a large drive to a nearly full AnyRaid pool to redistribute tiles and unlock usable space.
- Avoid filling tiles prematurely to preserve flexibility for future reflow and device removal.
