Re: [zones-discuss] Can a non-global zone mount an NFS file system from its own global zone?
Hi John, to clarify, I don't want to mount a root-zone exported filesystem, but, from within the zone, I want to simply leverage the root-zone's automount tree to provide access to each non-global zone to our (seperate) NFS fileservers. I think the technical discussion above gets into the details of this scenario. Hi Niko, I'm glad you feel the same and also want to speak up about about it! (I started a thread in the brandz forum, it's now on the topic of 64bit lx, there are more details there of our environment) Here are the details of my goals: (2 flavors) I would like to build a display-server with 100 users, each with their own personal brandz-Linux zone. Their /pkg or /app space would be a (replicated to the display server) zfs filesystem in the root zone. (lofs this, the simple part). Their /prj or /project space would be the same auto.projects map which all other solaris and linux boxes have. (the heart of this discussion.. I don't want 100 autofs5 daemons running)) the other flavor goes like this: in our LSF farm we generally have 2 kinds of queues (or Job Profiles): large mem (32-64GB) single-core, and multi-core ( =4 core) small-memory 4GB. with a 16 thread, 144GB Nehalem server, we need to have job-slots for both kinds of these; currently with LSF it is impossible for us to have a single machine in both kinds of queues. To go further with my idea, I want to use Solaris resource-controls to help buffer the load, in addition to LSF or Sun Grid Engine to buffer and schedule the jobs before dispatch. You spread those two flavors over a bunch of new modern hardware, and you have a new model which (IMHO) implements virtualization done right.

Hi Niko, this thread had 150 hits in the last three weeks, the topic is in the FAQ since 2005, and the question comes about every 9 months or so. So it seems it would be a desired feature! I expect it would be most utilized in shops who have thousands of automount map entries, and hundreds or thousands of boxes they would like to put in branded-zones. People would otherwise ask why not just run (solaris: automountd) or linux: autofs4? well, autofs4 crashes, autofs5 does not seem to work with the brandz fake-kernel, and well, it's just plain silly to run 100 seperate autofs daemons under containers, when lofs and some idmapd like thing would satisfy the problem. [...on with the advocacy hat...] Resource-controls on a brand-z container, minimal OS overhead, and 64 bit support someday. I think those are the keys needed win a bakeoff with an outcome of linux containers under Solaris is 200% more efficient than any other virtualization when consolidating 100 vm's to one physical machine. To demonstrate this, imagine a Linux (or Solaris) image with a 5000 entry automount map, and 100 VM's kicking the automount daemon every 15 minutes to scan for new mounts, running 100 Kernels and name service daemons under vmware or xen Think of the I/O and CPU overhead for an otherwise idle system. I would pay for Subscriptions Support for Opensolaris 2009.6 if it had it today. Regards, Rob -- This message posted from opensolaris.org ___ zones-discuss mailing list zones-discuss@opensolaris.org

The answer is no. 5065254 NFS/UFS deadlock when system is both NFS server and client Use LOFS.

Re: [zones-discuss] Can a non-global zone mount an NFS file system from its own global zone?
You should give exact version. It's unsupported on S10. And any attempt to obtain a fix (even with some automagic automounter feature which would transform mount into a lofs) is returned as a NO WAY !. It would be fun to have some sort of survey to see how many people would be interested in such feature. Nico ___ zones-discuss mailing list zones-discuss@opensolaris.org
