Import Netapp snapshot volume into ovirt and start VM from volume snapshot
by Igor Zinovik 30 Jul '18

30 Jul '18

Hello. I'm trying to implement following backup scenario for my VMs: storage domain is a volume on netapp appliance connected to oVirt cluster via NFS3. Netapp produces its zero copy snapshots of this volume. I want to be able to restore VMs from these snapshots, e.g. Netapp can export snapshot to ovirt as another NFS volume after that I want to be able to import VM or attach VM disks from snapshot volume to VM and start it. As far as I understand it is basic backup|migration scenario when user wants to move VMs from one ovirt DC to another ovirt DC. Right now I cannot import snapshot volume which contains exactly same domain metadata (in dom_dm/ directory) as original volume (which I cannot detach since it hosts disks for running VMs). I tried to rename dom_md/, but with no success in domain import process. Maybe someone in this list uses same scenario for VM backup and can give some advice.

I've got one physical host in a 3 host CentOS7.5 cluster that reports the following error several times a day VDSM node3.example.com command Get Host Statistics failed: Internal JSON-RPC error: {'reason': '<Fault 1: "<type \'exceptions.AttributeError\'>:\'NoneType\' object has no attribute \'statistics\'">'} Any ideas what the problem might be?

Fwd: Re: up and running with ovirt 4.2 and gluster

---------- Forwarded message --------- From: Jayme <jaymef(a)gmail.com> Date: Sun, Jul 29, 2018, 10:09 PM Subject: Re: [ovirt-users] Re: up and running with ovirt 4.2 and gluster To: Mike <xenithorb(a)fedoraproject.org> On this same subject one thing I'm currently hung up on re: HCI setup is the next step in the cockpit config for glusterfs. I have three nodes setup with two drives each in jbod. On the brick config screen you have to specify the device location and size of each of the volumes you configure on the previous step i.e engine and data. It seems that I can only specify one of my drives for the data volume. So I'd have to pick /dev/SDA drive for engine and /dev/sdb for data, but I have 2x2tb drives what do I do with all the other space on the devocd I put the engine volume on? If I choose to use sdb for data and have it 1.8tb does that mean the data storage will only use one single drive in each of my three nodes? I want to make use of all six drives to increase I/o performance. I don't understand how the jbod config of gluster is suppose to work. What if I had even more drives in each node say 4 separate drives how would I make use of all drives when I can only specify one device for each volume? I'm thinking about creating a data and data2 volume and specifying SDA for data and sdb for data2. Am I completely misunderstanding the setup here. Its very confusion and there is next to no documentation on HCI available.

Hosted engine unaviable after storage rebuild
by sebastian.w＠gmx.ch 29 Jul '18

29 Jul '18

Hello all, My hosted engine does not start up anymore, because the node can't reach the storage. The hosted engine configuration has not been retrieved from shared storage. Please ensure that ovirt-ha-agent is running and the storage server is reachable. What happend is that my NAS crashed and I had to rebuild it from the backup. I'm quit sure that I called all the NFS shares the same way as they bevore the issue. How can I figure out whats the issue with the storage? The logs wheren't realy helpful for me (but may it's me and not the logs to blame) Regards and thanks Sebi

Changing Network Interfaces on host causes bond to go offline
by oBSD Nub 28 Jul '18

28 Jul '18

Everytime I try to change assigned Logical networks (add ip addresses, assign a logical network, etc) the bond0 interface winds up going down. I have to do a ifup bond0 from the console, and the engine reconnects. After a lot of digging, I think this is the offending command, but I don't know how to read it or next troubleshooting steps. Anyone want to point me in the right direction?
