zfs discuss - Apr 2009 - Add WORM to OpenSolaris

Has anyone created a opensource plugin for WORM (Write Once, Read Many) for
OpenSolaris?
Any ideas how hard it would be to create this?

Wow... that''s seriously cool!

Throw in some of this... http://www.nexenta.com/demos/auto-cdp.html  and
now we''re really getting somewhere...


Nice to see this level of innovation here. Anyone try to employ these
types of techniques on s10? I haven''t used nexenta in the past, and
I''m
not clear in my mind (yet) how much of this is userland/script based vs.
deeper/kernel level stuff.

Thanks,

NexentaStor auto-cdp service is based on Sun StorageTek Availability
Suite and does not utilize ZFS.

So yes.
