Nevada Build 128 BFU's Ready

24 Nov '09 - 20:34 by benr

Nevada Build 128b (snv_128) is now closed and available as BFU or source tarball. This means that those who want to play with ZFS Dedup but don't want to build from source can give it a go.

It should be said that there have been a lot of exciting enhancements to Nevada over the last couple of builds. Here are some of the changes in the last couple builds:

ZFS Dedup
zpool recovery support
More ZFS fixes and improvements than you can shake a stick at
Solaris now has bridging, and RBridges (IETF TRILL)
Crossbow now provides link-protection (IP Anti-Spoof); this was a Joyent request we're glad to see incorporated
Flowadm now implements remote_port attribute (was in the man page since the beginning but only added in 126)
ksh93 update 2
Solaris Hotplug Framework
Smartcard support was ripped out
ILB: Integrated L3/L4 Load balancer ... yes, thats right, a L3/L4 Load Balancer integrated INTO the Solaris kernel! This is my play toy atm.
iSCSI Boot
Piles and piles of COMSTAR and FCOE enhancements
FMA for Nehalem_EX
Solaris 10 zones
Fast Crash Dump
Lots of Audio improvements
Clearview IP Tunneling (ie: create IP tunnels via dladm and associate resource controls like any other link)
Datalink Administration from Non-Global Zones
Solaris Packet Capture
Marvell Yukon Gigabit Ethernet Driver
... and on and on and on.

If your not running at least Build 121 your really behind the times, and I highly recommend that if you have the time to install SX:CE 127 and BFU up to 128... or, if your busy with the holidays, make sure you set aside some time in December to really dig into the new hotness when SX:CE 128 releases.

UPDATE: It was announced that there shall be No SXCE 128 Release due to CR 6903705. So if you were waiting to avoid a BFU or full compile you should bother waiting unless you can hold out till mid December for 129.

Also, do remember, the clock is ticking on SX:CE. I still have hopes for a reprieve from the powers that be to keep SX:CE alive, but you never know. If that happens either be prepared to get really comfortable with BFU or code building, or get ready to embrace Indiana with both arms. Solaris 10 proper is of course an option, but not a great one.

UPDATE 2: Changed link to the re-spin snv_128b.

Just a heads up: [zfs-discuss] heads-up: dedup=fletcher4,verify was broken

A respin of b128 is supposed to be done – I’m not sure when that will hit the streets…

“If your not running at least Build 121”

Just curious, what does Joyent run in production?

Karl (Email) - 24 November '09 - 21:58

128 SXCE won’t be released, so next opportunity looks like 129 –

I look forward to your comments about the ILB…

Che (URL) - 25 November '09 - 00:10

@karl: A lot of our infrastructure is still on snv_89, which has proven to be an exceptionally stable platform; builds 90-120 weren’t suitable for us. snv_121 was put through extensive trials and we’re preparing to re-standardize on snv_127 after discovering some obscure production issues with 121 which are specific to our use cases. Due to dedups integration I’m leary of putting it in full production so soon, so I’m hoping to vet all the 127 issues (there are a couple internal workarounds for things we’ve found) and proceed with that.

For anyone interested in the subject, the reason for going from snv_89 to snv_127 is really to give us,as a provider, additional functionality (Crossbow, ZFS improvements, better resource controls, etc.) The user experience stays essentially unchanged, with some minor exceptions. We’ve also been adopting Nehalem based systems, which combined with Solaris power management provides way more performance with a lot of eco-savings, for folks who are into that sorta thing.

What makes ILB different from LVS which has been integrated for eons? Once you get some experience with it PLEASE write a post about it.

Reading about “What does Joyent use” made me wonder what version of zpool and zfs do you use?
I assume when dedup comes out we would need to upgrade pool/zfs to take advantage.

opensolaris.org states, SX:CE is discontinued :(
[[http://hub.opensolaris.org/bin/view/Ma..]]

Solaris Express Community Edition is no longer a recommended download and builds will not be available past October 2009 (see email announcement). SXCE has been superseded by the OpenSolaris OS and represents the older generation developer build of the Solaris OS. Also known as Nevada, it is updated every two weeks and available as a free download. It is usually updated every other Friday and its release is announced on the OpenSolaris announce forum. Note that CD media is no longer available for SXCE but Build 98 images are for those interested: CD.

If you have any Linux NFSv4 clients you really want to be on snv_126 or later, because of bug #6854659. I’m looking at upgrading our servers because we have users being bit by this one while doing Subversion checkouts.

David (Email) - 25 November '09 - 23:29

SXCE b125+ has a bug in the gnome desktop where you can’t right click and pop open a new window is your default shell is /bin/sh or /bin/ksh. I think this is terrible, but the OSOL developer who responded to the bug said ‘CLOSED:WONT FIX’ because SXCE b130 (?) is end of the road for Nevada (SXCE). I think this is a crock of poo-poo, because ksh is king around these parts and bash is only preferred by them linux wankers.

source: [[http://defect.opensolaris.org/bz/show_..]]

workaround: learn to love /bin/ksh93 as your default shell, even for root.

brb, busy downloading b128 as the golden final release…

“Also, do remember, the clock is ticking on SX:CE. I still have hopes for a reprieve from the powers that be to keep SX:CE alive, but you never know.”

Although I hate sounding like “me too”, so do I, so do I. Killing SX:CE is a huge blow to system engineers like myself, because the ground is going to be pulled from under our feet, and we’re expected to make do with the OpenSolaris distribution, a product highly unstable, geared towards a casual GNU/Linux user, and inferior to what would have been Solaris 11 in just about every resoect, with every technical decision being wrong or awkward (GNU utils and bash as the default being the most obvious).

If they expect us to use OpenSolaris to do STABLE development and TESTING on, they’re simply insane. There is no way we can have software ready for the future for an operating system that has been so bastardized, that it’s hardly recognizable as a Solaris variant.

“If that happens either be prepared to get really comfortable with BFU or code building, or get ready to embrace Indiana with both arms. Solaris 10 proper is of course an option, but not a great one.”

Considering the alternatives, my company and I will take our chances with Solaris 10 any day of the week.

It’s good to see at least a few people who feel like I do about the switch from Nevada to OpenSolaris. I was starting to think it was just me, that I’d reached that age where you get mired in the past, stuck with what you’re comfortable with. I keep trying OpenSolaris, keep giving it another chance, but it’s not still not fit for what I do for a living. What happened to Sun’s much vaunted backward compatibility? I’ve had SHELL SCRIPTS that don’t work on OpenSolaris. Well written ones too, that work flawlessly on everything from 2.6 to nv-b127.

It seems stupid trying to turn a server O/S into a desktop O/S, especially now so many people have already switched to Macs, and MS have finally got Windows to a point where it’s more than useable. (That comes from a man who’s used a Solaris x86 desktop every day since Solaris 7!) And a server O/S that doesn’t have an automated installer and can’t do upgrade installs? PLEASE!

I honestly don’t know whether to force myself to move to OpenSolaris, so I HAVE to learn it. Maybe I’ll learn to love it. But it feels like such a fundamentally flawed concept that I can’t see anyone using it, then I’d have wasted my time.

Hi all.

First of all, seems that SXCE:129 is out, at least this download link works now:

https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_SMI-Site/en_US/-/USD/ViewProductDetail-Start?ProductRef=Sol-Express_b129-FULL-x86-SP-G-B@CDS-CDS_SMI

I have no idea if it’s a complete or working build; the links from OpenSolaris hub site lead to build 127 at the moment.

(What’s with your antispam? I’m too determined to post my comment to support SXCE, otherwise I wouldn’t have tried for so many times!)

Second, also count me in as a Solaris user sad to see the legacy-compatible system go, which includes compatibility with older software and its users’ knowledge as well. I did try OpenSolaris builds once in a while (not to much to be honest) and they seemed somewhat usable. I did not make up my mind that they seem like what I “wannahave” on each of my servers, and it did not seem like it knew much of my laptop’s hardware.

I did not encounter the issues stated above, like incompatibility with “old” scripts or the installer problems. Then again, I did not yet test it even that much ;)

//Jim

Jim Klimov (Email) - 10 December '09 - 08:29

But indeed, having to (being forced to have to) learn the whole new system and concept of IPS is uncool. From what I hear and see, there’s a major problem of even getting a local repository of the current build working as to save traffic and have upgradability for truly private networks – something that a simple installation DVD/ISO solves.

When we are upgrading SXCE servers, it is because we are moving to a superior version of what we already have, and we know how to use it and what to expect. Even if there are bugs, there’s a fallback strategy like reverting to an older build and try a different upgrade path, or use some (often) easy-to-guess workarounds.

//Jim

Jim Klimov (Email) - 10 December '09 - 08:32

I won’t go as far as others to state that Indiana is in principle a worse choice and will always be. I just don’t want that choice to be made for me. And if there are issues like breaking a legacy and like those problems described by other posters, I certainly don’t want this choice to be made for me so soon. If it is the new Solaris, may be it should be QA’d for stability and compatibility, ripened and hardened, and released as “Solaris 12”, not “Solaris 11”? It may be a leap forward, but stability-concerned customers walk in steps, not leaps.

Hope this counts as a +1,
//Jim

Jim Klimov (Email) - 10 December '09 - 08:40

Even if the major change has to be done eventually, it has got to be for the better. And really “better”, in all aspects at that moment.

I don’t want to receive a pretty desktop instead of a stable efficient server (maybe alongside, but not as replacement). We already have Windows for that kind of choice ;) and they are evolving…

I won’t even see this desktop over a server’s serial console ;(

Hey BenR, why don’t you write up a quick perl script that gets rid of all these annoying spam posts from “Christian Louboutin Shoes” and “Cheap UGG Boots” and then write about your script in an upcoming blog entry. UNIX was built for scripting and automation, and scripting and automation is a great way to delete any and all posts from a blog that mention UGG Boots or whatever other crap these losers are peddling.
