[zones-discuss] Centralized Zone Management Tool
Hello World, I started to think about a centralized zone management utility / system. I know exactly one tool that does this, which is proprietary, expensive, complicated and has too much half baked features. xVM ops center doesn't do what I need either and is closed source too. It's time to scratch an itch. To further illustrate what I'm thinking about here some use cases: crud (create, read, update, delete) on zone configurations state changes of zones (boot, halt, restart, ...) migrate a zone from one host to another to build ha / desaster tolerant solutions administration of the underlying storage of a zone (san luns, isci, nfs, zfs, - you get the idea) is propably the toughest part, I guess keeping this out of scope in the first phase is a good idea ;) I'm eager to hear what you the opensolaris zone community thinks about such a tool, who would like to help me do a little initial design work in the inception phase. Thanks for your time and input. Regards Robert -- This message posted from opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org

Regards Robert Puppet manages zones, ZFS, NFS, and you could write providers to do the rest. Puppet is free, well-written, and has a great dev team. It's also being incorporated into many other management projects (like Cobbler), so you could say it's either already or on its way to becoming an industry standard. The DR stuff would probably be non-trivial, though in my shop I just move the zone class to another host, boot it, it mounts the data via NFS or what have you, and I'm done. -- bda cyberpunk is dead. long live cyberpunk. ___ zones-discuss mailing list zones-discuss@opensolaris.org
Re: [zones-discuss] Centralized Zone Management Tool
I'm already using puppet at home and at work - and I love it (planning the migration to 0.25 right now ;). I've not used the zone resource type yet but will give it a shot asap. However, I need some time to get used to the idea that we might migrate our zones through editing a puppet manifest. It's either scary or sexy as hell - have to spend some time with the zone resource type and the code... ;) Regards Robert -- This message posted from opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org
Re: [zones-discuss] exclusive-ip
Have any GLD drivers for qfe on sparc been released? I'm looking for developments on this. What's the likelihood, that, drivers for sparc-opensolaris, will, on, Solaris 10 sparc, work?

What's the likelihood, that, drivers for sparc-opensolaris, will, on, Solaris 10 sparc, work? Kartik Vashishta The Nevada (OpenSolaris) qfe drivers are GLDv3 based. These drivers however will not directly work on Solaris 10. The GLDv3 qfe driver depends on the GLDv3 hme driver so first you would need to backport the hme driver to Solaris 10 and then the qfe driver. There are only a few code changes necessary to do this but this will still not be done because there are several interface changes which will break compatibility (e.g. when using the ndd command on /dev/qfe and instance vs. /dev/qfeinstance). So most likely there will not be any GLDv3 based qfe driver for Solaris 10. See RFE 6590092 (qfe) and 6568532 (hme) which both have the request for Solaris 10 backports (not done though).

[zones-discuss] Zone Stuck in down state - nfs share
I needed to share out a non-global zones folder via nfs so I did it from the global zone like so: # share /slabzone1/zonepath/root/home Later I rebooted the zone: # zoneadm -z slabzone1 reboot The reboot command hung and the zone became stuck in the down status. I assume this is because of the nfs share, I tried unsharing it, but that didn't help: # unshare /slabzone1/zonepath/root/home nfs unshare: /slabzone1/zonepath/root/home: not shared My attempts to get the zone to transistion to installed state have all failed. I assume this is a known issue, is there anyway to recover without a reboot? Thanks, Alex ___ zones-discuss mailing list zones-discuss@opensolaris.org
Re: [zones-discuss] Zone Stuck in down state - nfs share
You can look at the following thread where I had a similar problem with a zone stuck in a shutting down state: http://opensolaris.org/jive/thread.jspa?threadID=101438tstart=30 The other thing to look for is processing that might be accessing the ngz from the gz using fuser. You can also use pwdx /proc/* | grep slabzone1to find process. If you find any you can see what they are doing and kill them, then try shutting down the zone again. Otherwise I haven't found a way to kill the short of rebooting the box. As an aside, I was under the impression that it was not advisable to access ngz filesystems from the gz. A quick search only seems to point to the gz possibly doing something nefarious to the ngz but I can't find any technical reason it shouldn't be done.

[zones-discuss] prebuilt solaris 10 container pkgs
I've uploaded prebuilt SVr4 pkgs onto the project page for the solaris10 brand that we're building. http://opensolaris.org/os/project/s10brand/ I'll do this from now on as we sync to each nevada build. The current pkgs are meant to be used with b118. The OpenSolaris dev repository should be hosting that soon (next week I think). This might make it easier for people who want to play around with the brand. Since these are development bits, not everything is going to work properly inside the zone but overall it is pretty usable at this point, although we only work with shared stack right now and delegated ZFS datasets don't work yet. Feel free to send us feedback if you try this out and let me know if there are any questions. Thanks, Jerry ___ zones-discuss mailing list zones-discuss@opensolaris.org

It's either scary or sexy as hell - have to spend some time with the zone resource type and the code... ;) Migrating in my context is ensuring the zone is stopped on the original host, and then including the zone manifest (which includes the zone resource, and the zone's node resource) in the new host. My stuff is not smart enough to copy required data, etc. I was not referring to the Sun concept of zone migration, which includes the above (and might actually work now, with upgrade on attach), but which in my shop would be a lot of tedious overhead (I like zfs send as much as the next guy, but... :) I'd be happy to share manifests, but they're still first-run (though over a year old) and sort of ghetto, in terms of current Puppet BCP. -- bda cyberpunk is dead. long live cyberpunk. ___ zones-discuss mailing list zones-discuss@opensolaris.org
