Hey everyone, This is just a quick announcement to say that the ZFS on OS X port is now posted for your viewing fun at: http://zfs.macosforge.org/ The page is also linked off of the ZFS Open Solaris page under "ZFS Ports": http://opensolaris.org/os/community/zfs/porting/ This page holds the status for the ZFS on OSX port and includes a small FAQ, some known bugs, announcements, and will include more as time goes on. It also holds the latest source code and binaries that you can download to your hearts content. So if you have a Mac, are running Leopard, and are feeling bleeding edge please try it out. Comments, questions, suggestions and feedback are all very welcome. I also want to point out this is BETA. We''re still working on getting some features going, as well as fleshing out issues with Finder, Disk Util, iTunes, and other parts of the system. So when I say bleeding, I''m not kidding :) However I''m excited to say that I''m happily running ZFS as my home directory on my MacBook Pro which is what I work off of every day, and am running weekly snapshots which I ''zfs send'' to my external drive. Oh happy day. thanks! Noel Dellofano

Just curious as ZFS and DTrace are the only things in Leopard that are of interest to me and I just can''t bring myself to pay (again) to upgrade MacOS X for two features that were developed for Solaris and are open source :-) Thanks. -- Darren J Moffat

Heh, good point :) However, ZFS is only available on Leopard, since it requires some changes and symbols that are only part of the Leopard kernel. On the plus side ZFS and Dtrace are really freakin cool so maybe that will help mitigate the ouch factor on the upgrade; just think of all the glorious hours of engineering you''re getting for one upgrade :) Noel On Jan 9, 2008, at 2:19 AM, Darren J Moffat wrote:> No?l Dellofano wrote: >> Hey everyone, >> This is just a quick announcement to say that the ZFS on OS X port >> is now posted for your viewing fun at: >> http://zfs.macosforge.org/ >> The page is also linked off of the ZFS Open Solaris page under >> "ZFS Ports": >> http://opensolaris.org/os/community/zfs/porting/ >> This page holds the status for the ZFS on OSX port and includes a >> small FAQ, some known bugs, announcements, and will include more >> as time goes on.

No?l, To try and get regular use out of ZFS on OS X I moved all of my Music directory a mirrored pool implemented as a slice of my internal disk and a FW enclosure. There are a few issues I see in using ZFS for end user applications at the moment. 1) Trash doesn''t work You adding files to the trash seems to work but you can''t empty it without manually going to the .Trashes directory and manually removing files 2) You can''t download new iTunes Store music through iTunes iTunes can download podcasts and add new music from local files even using the consolidate music option 3) It was somewhat prone to causing panics mainly bringing devices back online or rudely disconnecting them 4) once the kext is loaded it appears that any user can perform any action e.g. anybody can create or delete a snapshot or a pool Shawn On Jan 9, 2008, at 2:26 PM, No?l Dellofano wrote:>> As soon as I get in to work and can backup my sparsebundle to a spare >> MBP, I''m going to start banging on it. > > Sweet deal :) > >> So, do you have all of /Users on zfs, just one account, have you >> tried >> a FileVaulted account too?

As I mentioned, ZFS is still BETA, so there are (and likely will be) some issues turn up with compatibility with the upper layers of the system if that''s what you''re referring to. But we''re working hard on fixing these as they come up. So end goal is there shouldn''t be any weird compatibility issues with the rest system.

Yep, these issues are known and I''ve listed them with explanations on on our website under "The State of the ZFS on OS X World": http://zfs.macosforge.org/ We''re working on them. The Trash and iTunes bugs should be fixed soon. The "your non-replicated drive just went MIA" panic will take a little longer as it requires a more complex fix that will need to involve diskutil and friends while also preserving the integrity of your pool and all the data therin. This is also a problem the Solaris ZFS team is working on as well, it''s just not as common that people rip out live drives from a Thumper :) Noel On Jan 9, 2008, at 2:45 PM, Shawn Ferry wrote:> No?l, > > To try and get regular use out of ZFS on OS X I moved all of my > Music directory a mirrored pool implemented as a slice of my internal > disk and a FW enclosure. > > There are a few issues I see in using ZFS for end user applications > at the moment. > > 1) Trash doesn''t work > You adding files to the trash seems to work but you > can''t empty it without manually going to the .Trashes > directory and manually removing files > 2) You can''t download new iTunes Store music through iTunes > iTunes can download podcasts and add new music from > local files even using the consolidate music option > 3) It was somewhat prone to causing panics > mainly bringing devices back online or rudely disconnecting > them > 4) once the kext is loaded it appears that any user can perform any > action e.g. anybody can create or delete a snapshot or a pool > > Shawn > > On Jan 9, 2008, at 2:26 PM, No?l Dellofano wrote: > >>> As soon as I get in to work and can backup my sparsebundle to a >>> spare >>> MBP, I''m going to start banging on it. >> >> Sweet deal :) >> >>> So, do you have all of /Users on zfs, just one account, have you >>> tried >>> a FileVaulted account too?

Okay, great. I''ve been enjoying ZFS on my home OpenSolaris box, and I have a new multi-drive Mac in my near future, and I''d love to have ZFS as an option at some point.

I never ran an OS X system on UFS myself, but it''s not surprising that some parts of the system/applications chafed at a case sensitive, data fork fs, although Apple does support it. --Toby> But we''re working hard on > fixing these as they come up.

The panics when brining devices online were always for mirrors. I realize that I wasn''t clear before. Since the by request only 101 and continuing with the 102A release, I have been able to do rude things to the external portion of my mirrors without experiencing a panic.> This is also a problem the Solaris > ZFS team is working on as well, it''s just not as common that people > rip out live drives from a Thumper :)That was almost the first thing I did when we got one to play with :)> > > Noel > > On Jan 9, 2008, at 2:45 PM, Shawn Ferry wrote: > >> No?l, >> >> To try and get regular use out of ZFS on OS X I moved all of my >> Music directory a mirrored pool implemented as a slice of my internal >> disk and a FW enclosure. >> >> There are a few issues I see in using ZFS for end user applications >> at the moment. >> >> 1) Trash doesn''t work >> You adding files to the trash seems to work but you >> can''t empty it without manually going to the .Trashes >> directory and manually removing files >> 2) You can''t download new iTunes Store music through iTunes >> iTunes can download podcasts and add new music from >> local files even using the consolidate music option >> 3) It was somewhat prone to causing panics >> mainly bringing devices back online or rudely disconnecting >> them >> 4) once the kext is loaded it appears that any user can perform any >> action e.g. anybody can create or delete a snapshot or a pool >> >> Shawn >> >> On Jan 9, 2008, at 2:26 PM, No?l Dellofano wrote: >> >>>> As soon as I get in to work and can backup my sparsebundle to a >>>> spare >>>> MBP, I''m going to start banging on it. >>> >>> Sweet deal :) >>> >>>> So, do you have all of /Users on zfs, just one account, have you >>>> tried >>>> a FileVaulted account too?

As for the resource fork, ZFS supports named streams/EAs natively so this won''t be a problem. Even with our old implementation of UFS, resource fork support and functionally was still 100% present, though admittedly 2nd class via Apple Double or those "turd" files we''re all fond of. Chris
