My last-night's posted question on mirroring suggested ZFS as easiest way.

So, how to get ZFS.

Right now, I have 9. (Have been negligent not going to 10.)

Also, I hear people here (c.u.s) being so haappy with "open"
solaris "(to be s11) -- probably bug-free enough for me,
for simple programming and browsing (firefox, but SLOW it is)
but no NFS no networking (except plugging into household
net, for fast internet access). Simple stuff indeed.

Questions:

1: should I go to 10, or straight to "11"?

2: the suggested ZFS, suggested not quite ready yet, what about that?



3: with ZFS, is letting someone login to one of its padded-cells
100% (99.99%) safe, in that he can't access anything
you don't want him to?


4: If ZFS isn't fully out yet, when might it be?


THANKS!


David


PS: any decent s10 books yet coming out? (I will
periodically be asking this same question.)

Heck, why doesn't Sun PAY some people, like from
this group, to do it -- or at least one on the
new features in 10, in "11", etc!

The first release of Solaris to include ZFS was 06/06 (S10u2??). Of
course, it's highly recommended to get the latest release.

OpenSolaris has proved quite stable for me and has all the latest
features. Sun offers support for SolarisExpress (falls somewhere in
between OpenSolaris and Solaris10) and of course any Solaris 10
release.

The only caveat to ZFS is that the root file system must still be on
UFS.

Not sure I understand the question. ZFS is a file system and has user/
group permissions on files like any other file system. Are you
referring to ZFS snapshots?? Those are point-in-time read-only copies
of the file system.

It's fully out. Get the latest Solaris 10 or OpenSolaris release.

Oh? Last I heard, Sun had not yet released a means of backing up a ZFS
file sytem to tape. There is ufsbackup but no zfsbackup! You can make
a "snapshot" to a direct access device (disk) but not, AFAIK to tape.
That seems like a pretty big caveat to me!

What do people using ZFS do in lieu of sending tapes off site for
disaster recovery purposes? Ufsbackup of the snapshot?

Time to mothball that ancient stuff! :-)

Get the latest version of Nevada (build 85 as I type). I've used
nothing but various builds of Nevada on my desktop for about 2 years.
Ditto for my (non-technical) wife.

ZFS is very much ready for production use!

I think you might be confusing ZFS the file system with Zones the
virtulaisiation/compartmentalisation technology. Something running
in a zone is indeed 100% safe in the sense you mention.

It is already, though of course features are still being added (e.g.,
on disk encryption).

True, although that caveat will be going away with b87 or b88 of
Nevada. At least, that's the current plan. Roll on ZFS root!
