(Tue, 22 Jul 2008 01:48:18 +0000)
"Hurrah! 2.0 has been released!" said Matthew Dillon, announcing the eighth major release of DragonFly BSD. This release is the first to include HAMMER, a new clustering filesystem that already boasts an impressive list of features, including: "crash recovery on-mount, no fsck; fine-grained snapshots, snapshot management, snapshot-support for filesystem-wide data integrity checks; historically accessible by default; mirroring: queueless incremental mirroring, master to multi-slave; undo and rollback; reblocking; multi-volume, maximum storage capacity of 1-Exabyte." Other highlighted changes in this release include, "native fairq-queue implementation using ALTQ, for PF", and "native connection state recovery to PF, so router reboots do not drop active TCP connections."
The latest version of DragonFly BSD can be downloaded from a mirror. The download page explains:
"DragonFly CDs are 'live', which means that the CD will boot your system and let you log in as root (no password). You can use this feature to check for hardware compatibility and play with DragonFly a little before actually installing it on your hard drive."
