There's no way to expand/shrink Hammer volumes. Another way to
approach this - and it's not necessarily better or worse - is to use
Hammer's mirroring capability to move data to a larger disk and then
start using that one, or otherwise shift it around.
Well, there is a possibility to add and remove volumes other than the
root volume, but IMHO
it's still considered experimental. In combination with LVM you could
emulate expanding and
shrinking of a Hammer filesystem.

Im thinking about reloading my home file server with dragonflybsd. Mainly so
i can take advantage of the rather awesome looking HAMMER filesystem.
My home server has an Areca 1260 SAS raid card, which is reported as being
supported by the arcmsr man page.
Im looking for confirmation from other users that areca cards work well, and
that the admin tools are supported from freebsd or otherwise implemented
Also id like to get some feedback that HAMMER is up to the task of being
belted really hard over sustained periods.
Im also not able to see find a conclusive answer to if HAMMER can be
expanded (as im relatively frequently adding more disks, and expanding my
raid array - currently im using UFS tool growfs)
I have dabbled with ZFS on freebsd, but found it wanting. HAMMER seems much
more 'next generation' - rather than just collapsing some raid features in
to the filesystem.
