DragonFly's HAMMER2 File-System Receiving Christmas Improvements

Written by Michael Larabel in BSD on 15 December 2018 at 05:32 AM EST. Add A Comment

With DragonFlyBSD 5.4 having been recently released, development is back onto full-swing in Git master. DragonFlyBSD/HAMMER2 lead developer Matthew Dillon has been landing HAMMER2 file-system improvements that he hopes to back-port to stable in the coming weeks.

This latest round of HAMMER2 work for DragonFlyBSD includes meta-consistency protection for snapshots and crashes, guarantee of buffer cache consistency, clearing up front-end stalls during a file-system sync, improved snapshot operation, and more. This work is also moving towards HAMMER2 clustering work that is still among their plans for this next-gen BSD file-system.

More details on these December updates to HAMMER2 can be found via the DragonFly mailing list.
