HAMMER/HAMMER2 File-System Updates For DragonFlyBSD

Written by Michael Larabel in BSD on 27 March 2017 at 07:21 AM EDT. 5 Comments

Matthew Dillon has implemented HAMMER version 7 support in DragonFlyBSD as well as work on the still-experimental HAMMER2 file-system.

HAMMER Version 7 changes the CRC mechanic from an older, slow code-path to faster ISCSI CRC code. This new CRC code path is six times faster than the older code. HAMMER v7 was implemented with this code commit from a few hours ago.

Then for the HAMMER2 file-system there has been work on stabilizing cluster operations, some bug fixes, API changes, a HAMMER2 mount can now specify @LABEL, and other changes. Details on the HAMMER2 changes via this commit.
