There's sort of an experimental port to FUSE. Last I heard about it, it
isn't exactly stable and the ARC's missing too, or at least gimped.
There won't be in kernel ZFS due to license issues (CDDL vs. GPL).

Also if ZFS can be implemented completely outside of the Linux kernel
source tree as a plugin module then it falls into the same category of
modules as proprietary binary device drivers.
The Linux community has a strange attitude about proprietary drivers.
Otherwise I wouldn't have to put up

They're actually buying constant-sized chunks of virtual storage, which

Are there any updated guides/blogs on how to configure ZFS boot on a build 88
or later system?
If I already have an existing zpool, will I be able to just add a root/boot
dataset or does the root/boot dataset have to have it's own pool?
I have several working systems that have small UFS

Hi Max,
I re-ran the cp command and when it hanged I ran 'ps -el' looked up the cp
command, got it's PID and then ran:
# truss -p PID_of_cp
and it output nothing at all -- i.e. it hanged too -- just showing a flashing
cursor.
The system is still operational as I am typing into the browser.

Is your ZFS pool configured with redundancy (e.g mirrors, raidz) or is
it non-redundant? If non-redundant, then there is not much that ZFS
can really do if a device begins to fail.
It's RAID 10 (more info here:

Seems kind of old. I am using Generic_127112-11 here.
Probably many hundreds of nasty bugs have been eliminated since the
