Re: Replace bad Host from a 9 Node hyperconverged setup 4.3.3
by Strahil 10 Jun '19

Hi Adrian, Did you fix the issue with the gluster and the missing brick? If yes, try to set the 'old' host in maintenance and then forcefully remove it from oVirt. If it succeeds (and it should), then you can add the server back and then check what happens.

oVirt survey - May 2019
by Sandro Bonazzola 10 Jun '19

10 Jun '19

As we continue to develop oVirt 4.3 and future releases, the Development and Integration teams at Red Hat would value insights on how you are deploying the oVirt environment. Please help us to hit the mark by completing this short survey. Survey will close on June 7th. If you're managing multiple oVirt deployments with very different use cases or very different deployments you can consider answering this survey multiple times. Please note the answers to this survey will be publicly accessible. This survey is under oVirt Privacy Policy available at https://www.ovirt.org/site/privacy-policy.html The survey is available here: https://forms.gle/8uzuVNmDWtoKruhm8 -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://red.ht/sig> <https://redhat.com/summit>

Re: Clusters run virtual machines or Red Hat Gluster Storage Servers
by Strahil 10 Jun '19

10 Jun '19

OVirt + Gluster is called 'Hyperconverged' setup and it supports only replica3 or a 'replica3 arbiter1' volumes. Vmware VSAN is another popular Hyperconverged Setup but requires a lot of licenses. The CPU and Disk resources are plenty on virtualization Hosts and this setup allows you to save space by removal of the iSCSI/NFS/SAN dedicated system. The setup is quite popular and it works quite well, but requires a 10G network (as load balancing smaller NICs is very hard ) - if performance is required, while even a 1 gbit/s NIC is possible to be used. Note: 1gbit/s will provide no more than 87 MB/s on gluster level for all your VMs , which is very poor. If you have 4 hosts -> one of them will not be in the gluster setup, or you will have 2 separate gluster volumes like this: oVirt1- Replica for volume A oVirt2- Replica for volume A , arbiter for volume B oVirt3 - Replica for volume B,arbiter for volume A oVirt4 - Replica for volume B Then you add them as hosts in your oVirt setup.

Clusters run virtual machines or Red Hat Gluster Storage Servers
by xilazz＠126.com 10 Jun '19

10 Jun '19

Hi, everybody. When I was looking at the administrator's manual, it prompted Clusters run virtual machines or Red Hat Gluster Storage Servers. These two purposes are mad exclusive: Virtualization and storage hosts together. When I configured the cluster, I said that the glusterfs and virt I saw were alternatives to the two checkboxes. I would like to ask what happens when glusterfs and virt are in the same cluster? How can I use hosted engine when I have four nodes? Thank you very much for your reply.

oVirt hosted engine lost superblocks, need to recover data - 4.1
by marcushershberger＠locl.net 07 Jun '19

07 Jun '19

I have been working on this a few days now, though no solution seems to have emerged. I have an oVirt 4.1 hosted engine that is now failing to boot except into emergency mode. When xfs_repair is run, it gives an error saying that the primary and secondary superblocks are bad. Earlier this week, I was trying to install engine-backup because there were problems with the root partition being full. I was working on resolving dependencies for engine-backup when the hosted engine became unresponsive with an output about gov0 (which I believe is related to gluster), and I have not been able to boot it correctly since then. I am able to mount /var, and I have access to it, but that is not true for the root partition. What are some suggestions for recovering the data on the root partition? Thanks!
