Dominic - are you also using a cluster with gluster service enabled? what is the status of the host after you confirm shutdown? any error on log on this specific command? I have two hosts I want to remove -- one, a failed add that never completed, and the other, an F17 machine that I subsequently updated to F18. So neither of those hosts are actually connected to my engine. Their status is either non-responsive or maintenance, if I activate, it's the former, if I set it to maintenance, it's the latter. I can only attempt to remove in maintenance mode, so that's where I have them. There don't appear to be any errors confirming manual reboot. shireesh - not sure if relevant to this flow, but need to make sure removing a host from the engine isn't blocked on gluster needing to remove it from the gluster cluster if the host is not available any more, or last host in gluster cluster?

In addition, I do not like the execution of the SQL statements in the script. There is a SP called DeleteVds(v_vds_id UUID) and you should use that since it encapsulates all details.

I upgraded from oVirt 3.1.16 to 3.1.19 under CentOS 6.3 (yum update). The thing is now oVirt is not starting. The web interfaces says: Service Temporarily Unavailable, the VMs don't starts (the box is configured as all-in-one) I have 2 VMs on production. What I can do ?

First, thanks all for the replies. As I didn't know hoy to convert an storage domain to export, what I did is to reinstall the all-in-one, create the 2 VMs and then make a dd from the old image to the new one created. Just in case, how can I convert an storage domain to an export ? hacking its metadata, and it wouldn't have saved you copying the data. (not sure why you dd'd instead of mv'd in your case) Thanks.

The nodes are no longer available I want to get rid of them ovirt does not let me. I can delete from database but why not from the GUI? I am sure others may run into this problem as well. what happens to the status of the host when you right click on the host and specify you confirm it was shutdown? I'm having this same issue. Confirming the host is shut down doesn't make a difference. I'm seeing lots of Failed to GlusterHostRemoveVDS, error = Unexpected exception errors in my engine log that seem to correspond w/ the failed remove host attempts. is cluster defined as gluster as well? what is the status of the host after you confirm shutdown? any error on log on this specific command? shireesh - not sure if relevant to this flow, but need to make sure removing a host from the engine isn't blocked on gluster needing to remove it from the gluster cluster if the host is not available any more, or last host in gluster cluster? Yes, currently the system tries the 'gluster peer detach hostname' command when trying to remove a server, which fails if the server is unavailable. This can be enhanced to show the error to user and then allow 'force remove' which can use the 'gluster peer detach hostname *force*' command that forcefully removes the server from the cluster, even if it is not available or has bricks on it. what if it is the last server in the cluster? what if there is another server in the cluster but no communication to it as well? A quick look at code tells me that in case of virt, we don't allow removing a host if it has VM(s) in it (even if the host is currently not available) i.e. vdsDynamic.getvm_count() 0. Please correct me if I'm wrong. If that's correct, and if we want to keep it consistent for gluster as well, then we should not allow removing a host if it has gluster volume(s) in it. This is how it behaves in case of 'last server in cluster' today. true, but user can fence the host or confirm shutdown manually, which will release all resources on it, then it can be removed. I see. In that case, we can just remove the validation and allow removing the host irrespective of whether it contains volume(s) or not. Since it's the only host in the cluster, this won't cause any harm. In case of no up server available in the cluster, we can show the error and provide a 'force' option that will just remove it from the engine DB and will not attempt gluster peer detach. something like that. i assume the gluster storage will handle this somehow? What would you expect gluster storage to do in such a case? If all servers are not accessible to a gluster client, the client can't read/write from/to volumes of the cluster. Cluster management operations in gluster (like removing a server from the cluster) are always done from one of the servers of the cluster. So if no servers are available, nothing can be done. Vijay can shed more light on this if required. Assuming that some of the servers come up at a later point in time, they would continue to consider this (removed from engine) server as one of the peers. This would create an inconsistency between actual gluster configuration and the engine DB. This, however can be handled once we have a feature to sync configuration with gluster (this is WIP). This feature will automatically identify such servers, and allow the user to either import them to engine, or remove (peer detach) from the gluster cluster.

[Users] I can't figure out how to add a user?
First off, oVirt noob alert. That said, I have been able to figure out and over come most of my issues getting oVirt running on CentOS 6.3 the various documentation that is available, including this list's archives for the last few months. (Side question: I haven't found a good way to search the archives short of using site: within google search, but that does not seem to work so well, so I have been relying on gmail's collection of the messages since I subscribed a few months ago. Is there a better way?) Anyway, this one seems like it should be so simple that I feel like I must be missing some thing painfully obvious. That is, I don't seem to be able to create a user. The GUI's add button on the user tab just lets me search existing users, but does not provide anywhere to enter new user info. I have successfully added the admin@internal user several times while bumbling around with that interface, but this is not terribly helpful since it has always been there. To what I have added it, I am am not entirely clear. I don't see anything in the getting started guide, and the administrator guide just walks me through the same useless steps I mentioned above in the user tab. Any nudge in the right direction would be greatly appreciated. I'll even accept dope slaps at this point if warranted. =) Thanks in advance for your time and consideration. ___ Alan Johnson a...@datdec.com ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
