Just don't minimize the legal risk issue. Its very hard for a vendor to
ship/support this due to the potential risk. Its arguably hard for a
user to deploy zfs on linux due to the risk, unless they had a way to
argue that they are not violating licensing (can't intermix GPL and CDDL
and ship/support it) for commercial purposes.
Lots of folks can't claim the type of cover that a national lab can
claim (researching storage models). You have to decide if the risk is
If you were to do this, I'd suggest going the Illumos/OpenIndiana or BSD
route. Yeah, work still needs to be done to get Gluster to build there,
but the licensing is on firmer ground (hard to claim that an "open
source" license such as CDDL does not mean what it says).
Understand where you stand first. Speak to a lawyer type first. Make
sure you won't have issues.
And do remember, that while Oracle and Netapp have (for the moment)
de-escalated hostilities, Oracle did not provide indemnity to non-Oracle
customers. So Netapp (and others) *can* resume their actions. A
question was asked why not go after Nexenta versus others. Simple.
There are many others (e.g. more potential licensing/legal fees) as
compared to a single Nexenta. Its arguably less about rights as it is
revenue from legal action. But that stuff does happen ...
Oracle is probably the only one whom can ship ZFS anything safely. And,
I'd guess that they are perfectly happy with that situation.
