nevermind.. found the answer myself thank goodness. had to rename the volume back to the value of the msdUUID. not the spUUID, which I already tried. If its fatal to rename that volume... would be nice to have it lockedout or something? ----- Original Message ----- From: "Philip Brown" <pbrown(a)medata.com&gt; To: "users" <users(a)ovirt.org&gt; Sent: Tuesday, June 16, 2020 10:21:12 AM Subject: help: renamed master volume Im pretty new to ovirt. Trying to upgrade an old install from 4.1 to 4.3 on the way, I browsed into the Storage area, in one of the nodes. Noticed under the "Volume groups", area that the volumes were named after some loong ID string. Saw there was a "rename" button. figured it would be just like renaming a VM. thigns would just get auto adjusted. but after I renamed to something in english, the cluster is freaking out, "cant find master domain: u'spUUID=xxxxxxx, msdUUID=xxxxxxx' " and under Storage: Storage DOmains, the Data(Master) is down. How can I recover from this ASAP? :-(

Okay, since you asked: (note: this is in node 4.3.10. but hosted-engine is 4.2 I'd LIKE to upgrade it. but the upgrade process is broken. thats a whole nuther story, aobut how postgresql10 doesnt show up even though its required for yum update 'ovirt*setup' :-/) 1. go to individual node UI. 2. Click on Storage 3. Look at the right-sdie aera for "Volume Groups". click on the one that is for your master data volume 4. Click on the Rename button on the top right. Pick something sensible 5. wait a while, and eventually your cluster logs will freak out. Happily for me, since our VMs are very lightly loaded, this did not immediately cause a crash. But the cluster freaked out.. engine log spewed those errors after a while.. and in the cluster(engine) UI, it eventually showed Storage->Domains as offline. (well it shows the master as offline, and it didnt even know about the other ones any more, until I renamed it back) ----- Original Message ----- From: "Nir Soffer" <nsoffer(a)redhat.com&gt; To: "Philip Brown" <pbrown(a)medata.com&gt; Cc: "users" <users(a)ovirt.org&gt; Sent: Tuesday, June 16, 2020 10:56:45 AM Subject: Re: [ovirt-users] Re: help: renamed master volume On Tue, Jun 16, 2020 at 8:31 PM Philip Brown <pbrown(a)medata.com&gt; wrote: Did you rename the volume from within oVirt UI?
