Yes, it is.

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? > >> >> >>> >>>> >>>> Dominic >>>> >>>> On Sep 22, 2012 4:19 PM, "Eli Mesika" <emesika(a)redhat.com >>>> <mailto:emesika@redhat.com>> wrote: >>>> >>>> >>>> >>>> ----- Original Message ----- >>>> > From: "Douglas Landgraf" <dougsland(a)redhat.com >>>> <mailto:dougsland@redhat.com>> >>>> > To: "Dominic Kaiser" <dominic(a)bostonvineyard.org >>>> <mailto:dominic@bostonvineyard.org>> >>>> > Cc: "Eli Mesika" <emesika(a)redhat.com >>>> <mailto:emesika@redhat.com>>, users(a)ovirt.org >>>> <mailto:users@ovirt.org>, "Robert Middleswarth" >>>> <robert(a)middleswarth.net <mailto:robert@middleswarth.net>> >>>> > Sent: Friday, September 21, 2012 8:12:27 PM >>>> > Subject: Re: [Users] Is there a way to force remove a host? >>>> > >>>> > Hi Dominic, >>>> > >>>> > On 09/20/2012 12:11 PM, Dominic Kaiser wrote: >>>> > > Sorry I did not explain. >>>> > > >>>> > > I had tried to remove the host and had not luck >>>> troubleshooting it. >>>> > > I >>>> > > then had removed it and used it for a storage unit >>>> reinstalling >>>> > > fedora >>>> > > 17.
