Hi, I''m looking at using SolExp to test a possible Sun deployment when sol10u2 is available (supposedly with ZFS support). I''d like to run my root FS as ZFS, on two drives (mirroring.) SW mirroring would be fine. Is this functionality there yet? Everywhere I''ve looked refers to: http://blogs.sun.com/tabriz but this has not been updated in months. It looked like he had it (semi) booting in August of last year, I would have expected a few more updates. ;) So basically, just curious where support for ZFS as the root FS stands, and if it''s going to make it into u2, and if I can use ZFS''s functionality to do any kind of mirroring. Looking at high availability, so this is a necessary evil for me. :) Cheers, David This message posted from opensolaris.org

I expect either Tabriz or Lori will update their blogs when they''ve got a spare cycle :) I don''t think it''ll be in s10u2. I do expect that when we have rootable zfs that you''d be able to mirror your root fs with it. Don''t quote me :) best regards, James C.

What filesystems are safe to put into zfs today? So if we can not yet do /, can we do /usr, /opt, /var? I tried /opt and it sure works but how will this affect liveupgrade? David J.

But in the context of your question, I think only / and /usr are "special", so they''d be the problematic ones. ZFS will be great, because it means that we can claim back a lot of wasted disk space. Historically I''ve preferred to keep the OS on it''s own disk(s) and data and apps on others, but with 36 GB and 72 GB disks becoming the norm, this isn''t necessarily the best use of resources. -- Rich Teer, SCNA, SCSA, OpenSolaris CAB member President, Rite Online Inc.

Current plan for supporting root on zfs has it available at Update 4 of S10. Tabriz will update her blog one of these days soon to discuss the current state of the work. Lori David J.

Also, yes, mirroring will be supported. It will be different from SVM mirroring though. With SVM, you mirror individual file systems. With zfs, you will mirror a pool and then all file systems within that pool, including bootable file systems (of which there can be many), are automatically mirrored. Lori James C.

The install software can''t handle zfs file systems yet, so system software directories (/usr, /opt, /var, etc) should not be zfs file systems. Some will work, but you won''t be able to upgrade the system, either by liveupgrade or standard upgrade. I believe you would have problems with patching, too.

Reply to McPherson comment "I don''t think it''ll be in s10u2" - Do you have a realistic date when it will be in Solaris 10? It has been pushed back for at least three quarters now. There are a number of us who are beginning to loose credibility with the management types because Sun hasn''t delivered on this product. I''ve been a fan of Sun products since 1983, but lately it''s been hard to convince management. As of this writing, I''m proposing alternate solutions just to save face.

ZFS root support will not - it''s not done, and adapting admin/install to support selection of ZFS root will take some time as well. Are you experimenting with ZFS using Solaris Express? - Bart -- Bart Smaalders Solaris Kernel Performance barts at cyber.eng.sun.com http://blogs.sun.com/barts
ZFS (as you''ve tested in opensolaris) will release with Solaris 10 6/06. The ability to use ZFS for the root file system will show up in a later release of opensolaris and then followed by a Solaris 10 update release.

> Reply to McPherson comment "I don''t think it''ll be in s10u2"That''s referring to ZFS as the root FS, not ZFS in general. ZFS will be in s10u2. The support necessary to make it bootable (and hence usable as the root fs) will be in u4. Jeff
Hi, I''ve read the blog on how to config ZFS as root manually. That''s cool. Given that this is targeted for U4 though, and U3 should be released anytime now, I''m wondering when we might see even more up to date support in Nevada? Will more changes be put back soon? - Or have they already been putback and I just missed it?? -Kyle This message posted from opensolaris.org
Latest plan is to release zfs boot with U5. It definitely isn''t going to make U4. We have new prototype bits, but they haven''t been putback yet. There are a number of design decisions that have hinged on syncing up our strategy with other projects, or allowing some other projects to "gel". Main dependencies: Xen, some sparc boot changes, and zones upgrade. It''s coming together and I hope we can have some new bits putback shortly after the first of the year. Lori Alt Kyle J.

For some of us the most interesting part of this is the bits in ON not the installer bits - particularly those people interested in building their own distros of OpenSolaris. -- Darren J Moffat

We''ll work on making the ON bits available ASAP. The soonest we could putback is build 56, which should become available to the OpenSolaris community in late January. (Note that I''m not saying that we WILL putback into build 56 because I won''t know that until I have approval to do so, but that''s the soonest we could do it, given restrictions on the earlier builds.)
