Re: [Users] Node Stateless

Is there a working iso to test ? What needs to be done ? And also, what would you need to move forward on this task ? Hi Olivier, This is currently still a work in progress. I updated the wiki page a couple weeks ago with the latest status (and haven't managed to do any work on it since then). A basic summary: stateless works, but with some limitations. Limitations: 1. No swap or overcommit. We do not touch any disk at all, so there is no swap available, and thus no overcommit possible with a stateless node. 2. No local storage domain -- not a big deal since most deployments want shared storage of some sort, but same reasoning as #1 3. Limited support from engine/vdsm. This one is a bigger deal than #1 and #2. engine doesn't understand the concept of a stateless node, so it treats a stateless node the same as a stateful one. This results in the admin having to remove/re-add/re-approve the node on each reboot. All ISOs starting with 2.3.0 should have this support already. You simply need to add stateless (without quotes) to the kernel command line at boot, along with other auto-install parameters to configure the node and the host will be up and running. As for steps forward, we're currently focused almost entirely on getting a node based on F17 working right now. Once that is done and out the door, we'll re-visit this feature. If you're looking to get involved, some of the functionality for solving #1 and #2 is already available in the code. Basically, what needs to be done is add support in the TUI for AppVG and add some additional handling around AppVG in auto-install. As for #3, there isn't much left to do on the node itself, but we need a decision from the engine and vdsm teams on how they want to handle this long term. There are a few ways to do it, all of which have their own pros and cons. Mike Thank you !

Re: [Users] Windows install / activation issues.

I am slowly doing my stage two testing now. I have been finding very few issues that is pretty good since 3.1 is just going into feature freeze but I did find one that is kinda a show stopper and weird for me. I installed windows 2003 using my Dell CD on my Dell Hardware. On both ESXi and Xen Server windows authorization fine because the installer sees the Dell bias in some way but under oVirt it doesn't. From my research it looks like the feature is called SLP. Is there anyway to pass the Dell SLP info to the installer like it is done under both Xen and Vmware ESXi? I assume it would be a libVirt option of some kind I just can't find it. Some specific SMBIOS strings are being passed to identify the hypervisor. There isn't a feature that enabled passing select host bios strings in oVirt yet (patches welcome) but you can do this with a hook, see here http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=tree;f=vdsm_hooks/smbios;h=c61ce8e73dc66791eb0390be3e764541b34c1137;hb=HEAD Thanks Robert ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] Anyone started working on the documentation for GlusterFS and Ovirt 3.1 yet?

That is why I asked is anyone has started working on the doc's Here is the feature page: http://ovirt.org/wiki/Features/Gluster_Support We intend to add more documentation soon, though nothing else is available right now. I would start by browsing tohttp://www.gluster.org/ and read about the underlying technology (glusterFS, admin guide is good place to start). Read though there doc's but wasn't sure how much needed to be done using native glusterfs tools and how much is done using ovirt engine because of the fact it was recently integrated means there are still likely holes in the process. Most of the features mentioned in the feature page, except async tasks (rebalance volume, migrate brick) and bootstrapping changes are currently available from UI and REST api. You should run engine with the option InstallVds set to false and SSL disabled (on both engine and vdsm). When creating clusters, make sure you select the checkbox to enable gluster services, and always add hosts to such clusters from UI only. as for tips and hints, I will describe what you need in general (very high-level): - cluster and data-center - edit cluster and set the gluster check box - host side (vds): * install vdsm-gluster package * install all gluster-related packages * make sure all gluster related services are fully operational Didn't see vdsm-gluster when I built the nodes but when I looked for the package it was there. Already had all the glusterfs services running. - create new volume (volume is a collection of bricks which represent a collection of export domains): * allocate storage space on your host * make sure this space is exposed via export (NFS) directory * create new volume\bricks This is where I am confused. glusterfs supports 3 methods of exposing the cluster. Is ovirt using the NFS or the native(fs) method? If it is NFS why the interface for bricks? Wouldn't you just create a giant nfs share? This is the area I am most confused with and looking for hints on. To be more precise, glusterfs supports 3 methods of exposing a *volume*, and not cluster. A cluster can contain a number of volumes. In Gluster terminology, Bricks (server:directory) are building blocks of a volume. Volumes can be exported using native (GLUSTER), NFS or CIFS protocols, though only GLUSTER and NFS are available from the UI for now. A volume need not necessarily have bricks on all servers of the cluster. If you want one giant NFS share spread over all servers of the cluster, you'll have to use one brick from each of the servers when creating the volume, and then export the Volume via NFS. Feel free to ask glusterfs specific questions on the #gluster IRC channel on FreeNode.
