Re: [Users] Is there a way to force remove a host?

Dominic - are you also using a cluster with gluster service enabled? Yes Gluster Service is enabled. And I can not remove hosts from that cluster.

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? Yes, it is. that's a very important piece of information... is there a more detailed exception in the log on the error? can you uncheck gluster and try to remove it again? 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. For example, your script does not handle permission clean-up as the SP does and therefore leaves garbage in the database. In addition, a failure in your script may leave database in inconsistent state while the SP is executed in one transaction and will leave DB consistent. So, in short I would prefer in this case that the relevant SP will do the clean-up since this is the one that is used by the code and that insures (at least I hope so) , that all related entities are removed as well. > > Thanks > > -- > Cheers > Douglas > > _________________________________________________ Users mailing list Users(a)ovirt.org <mailto:Users@ovirt.org> http://lists.ovirt.org/__mailman/listinfo/users <http://lists.ovirt.org/mailman/listinfo/users> _________________________________________________ Users mailing list Users(a)ovirt.org <mailto:Users@ovirt.org> http://lists.ovirt.org/__mailman/listinfo/users <http://lists.ovirt.org/mailman/listinfo/users> -- @jasonbrooks -- @jasonbrooks -- Dominic Kaiser Greater Boston Vineyard Director of Operations cell: 617-230-1412 fax: 617-252-0238 email: dominic(a)bostonvineyard.org <mailto:dominic@bostonvineyard.org>
