Re: [osol-discuss] solaris 32bit broken - so when will it get discontinued ?
What makes you think a company would necessarily _have_ a policy on something like that they make it available and i don`t read from sun something like please don`t use, we don`t support it as good as 64bit if i would readmade just for your convenience, use at your own risk somewhere that would be something different. it`s just that i like to know it solaris 32bit is a dead child for sun or not and if it`s having really severe issues or if this is just FUD from single individuals... If it were me, I'd say ok for an older desktop or laptop, but I'd prefer the best I could afford for any kind of server. Besides, zfs on a file or media server would probably be happier with more RAM than most 32-bit only systems can handle. So...still useful? Depending on the use, sure. As good as 64-bit? Maybe not, even outside of any reliability concerns. In the long run, I suspect 32-bit of any OS will only be on embedded devices, phones, GPS receivers, and so on. Maybe on SCs for larger systems, too. :-) -- This message posted from opensolaris.org ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

Posted: Aug 6, 2008 10:59 PM in response to: Thomas Garner To: Communities » zfs » discuss In the most recent code base (both OpenSolaris/Nevada and S10Ux with patches) all the known marvell88sx problems have long ago been dealt with. However, I've said this before. Solaris on 32-bit platforms has problems and is not to be trusted. There are far, far too many places in the source code where a 64-bit object is either loaded or stored without any atomic locking occurring which could result in any number of wrong and bad behaviors. ZFS has some problems of this sort, but so does some of the low level 32-bit x86 code. The problem was reported long ago, but to the best of my knowledge the issues have not been addressed. Looking below it appears that nothing has been done for about 9 months. - furthermore, i have read several times, that 64bit solaris should preferred under all circumstances. that is a user`s opinion, but how does SUN think about that ? -- This message posted from opensolaris.org ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

[...] furthermore, i have read several times, that 64bit solaris should preferred under all circumstances. that is a user`s opinion, but how does SUN think about that ? What makes you think a company would necessarily _have_ a policy on something like that? Absent such a policy, why should any employee risk their job by presuming to speak for anyone but themselves? If the policy exists, the _most_ you can hope for is that one of them will know it, and repeat it. Plenty of folks aren't employees, either. I don't _think_ Sun currently sells any non-64-bit-capable systems on which they support Solaris, although I'm not positive. I don't know whether or not they sell support contracts for running current Solaris on non-64-bit-capable systems they don't sell, or don't sell anymore. If they don't do either of those things, I would expect patches to make Solaris more reliable on non-64-bit-capable systems to mostly come from outside of Sun, except insofar as very very specific problems are fixed when they're identified (like specific instances of non-atomic operations). So even if I didn't want to submit _patches_, if I wanted Solaris on such systems to be improved, I'd try to identify as many such specific instances of problems myself, and submit those as bugs, so that somebody else could perhaps do the code more quickly. OTOH, since a 32-bit version of Solaris is offered, it _would_ be nice if it were as reliable as the 64-bit version (on otherwise comparable hardware). But the mere fact it's offered doesn't imply that the resources exist to perfect it (without outside help). So I'm not sure whether or not there's an unreasonable inconsistency there. Then again, since all my hardware that can run current 32-bit [Open]Solaris is capable of running 64-bit as well, I don't really have a reason to feel strongly one way or the other. ( 2 UltraSPARC = II systems, one 64-bit-capable Intel Mac) Just my opinion. I don't work for Sun either. -- This message posted from opensolaris.org ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

This message is a broadcast of the previously mentioned bug, 6634371, by the person who filed it. What additional concerns does it raise from the original post? The ZFS specific version of this bug is: http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6735425 The description should ease concerns about the safety of ZFS under 32 bit kernels. If anyone believes something was missed, point me to the code and I will add it to the public description. ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org

[osol-discuss] solaris 32bit broken - so when will it get discontinued ?
Hello, i always wondered about the details why using 32bit solaris is not adviced - i now came across this one: http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6634371 Solaris ON is broken w.r.t. 64-bit operations on 32-bit processors as this bugreport is nearly 2 yrs old and in status dispatched, i`d wonder if issues like this will ever be fixed. so, what about the support status of 32bit solaris then and when is it going to be discontinued? i always thought the problems are theoretical or rare, but looking at issues like this, i won`t spend any minute on trying solaris on 32bit anymore. what i´m wondering a little bit is why it`s still running fine here on two systems. no zfs errors/problems or crashes or whatever -- This message posted from opensolaris.org ___ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
