The SDM is on an nfs share on a local disk instead of iscsi luns. I could cre less which is the SDM as long as my vm disks are on thee iscsi luns. That's all I want to accomplish. Reading the documentation, I understood that the SDM would hold all disks, vm info, etc. That's why I wanted to change it. As for the gluster, still working on that part. Its there but no bricks until I add the third host. I'm in the process of doing that now. However, I have no mount points to specify which disks I want to gluster on. Still trying to figure that out. I am doing a reply all on the email since I started this on the user list page. Is that ok or do I need to email someone specifically? I'm an ovirt noob. 😊 Eric Evans Digital Data Services LLC. 304.660.9080 -----Original Message----- From: Darrell Budic <budic(a)onholyground.com&gt; Sent: Friday, February 14, 2020 4:58 PM To: eevans(a)digitaldatatechs.com Cc: users <users(a)ovirt.org&gt; Subject: [ovirt-users] Re: glusterfs Hi Eric- Glad you got thought that part. I don’t use iscsi backed volumes for my gluster storage, so I don’t much advice for you there. I’ve cc’d the ovirt users list back in, someone there may be able to help you futher. It’s good practice to reply to the list and specific people when conversing here, so you might want to watch to be sure you don’t drop the cc: in the future. Re: the storage master, it’s not related to where the VM disks are stored. Once you mange to get a new storage domain setup, you’ll be able to create disks on whichever domain you want, and that is how you determine what VM disk is hooked up to what. You can even have a VM with disks on multiple storage domains, can be good for high performance needs. The SDM may even move around if a domain become unavailable. You may want to check the list archives for discussion on this, I seem to recall some in the past. You also should confirm where the disks for your HA engine are located, they may be on your local raid disk instead of the iscsi disks if the SDM is on a local disk… Good luck, -Darrell > On Feb 14, 2020, at 3:03 PM, <eevans(a)digitaldatatechs.com&gt; <eevans(a)digitaldatatechs.com&gt; wrote: > > I enabled gluster and reinstalled and all went well.

Ovirt has a feature to migrate date between storage domains you can use to move an existing VM disk to a different storage facility. Note that “reinstall” is an option on the Installation menu for hosts, you do not need to remove the host first. It will pretty much just add the vdsm-gluster components in this case, safe to use. Just put it in maintenance first. > > You can certainly start fresh in the manner you describe if you want. > >> On Feb 14, 2020, at 11:56 AM, <eevans(a)digitaldatatechs.com&gt; <eevans(a)digitaldatatechs.com&gt; wrote: >> >> I have already imported a few vm's to see how the import process would go.

First you need to enable Gluster in at the cluster settings level for a new or existing cluster. Then either install/reinstall your nodes, or install gluster manually and add vdsm-gluster packages. You can create a stand alone gluster server set this way, you don’t need any vddm packages, but then you have to create volumes manually. Once you’ve got that done, you can create bricks and volumes in the GUI or by hand, and then add a new storage domain and start using it. There may be ansible for some of this, but I haven’t done it in a while and am not sure what’s available there. >> >> -Darrell >> >>> On Feb 14, 2020, at 8:22 AM, eevans(a)digitaldatatechs.com wrote: >>> >>> I currently have 3 nodes, one is the engine node and 2 Centos 7 hosts, and I plan to add another Centos 7 KVM host once I get all the vm's migrated.
