ovirt 4.1.2 sanlock issue with nfs data domain
by Moritz Baumann 19 Jun '17

19 Jun '17

Hi, I'm still strugling to get our ovirt 4.1.2 back to life. The data domain is nfs and the nfs mount works fine. However it appears that the sanlock does not work anymore. Is there a way to "reinitialize" the lockspace so one node can become SPM again and we can run VMS. Best, Mo

Hosted Engine Setup with the gluster bricks on the same disk as the OS
by Mike DePaulo 18 Jun '17

18 Jun '17

Hi. I am trying to follow this guide. Is it possible to use part of my OS disk /dev/sda for the bricks? https://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4-1-and-gluste… I am using oVirt Node 4.1.1.1. I am aware of the manual partitioning requirements. I am guessing I have to create an LV for the OS that does not take up the entire disk during install, manually create a pv like /dev/sda3 afterwards, and then run Hosted Engine Setup and specify /sda3 rather than sdb? Thanks, -Mike

It is a quite normal HDD/XFS/NFS stack that worked quit well with 4.0 in the past. Inside the VMs we use XFS too. To our surprise we observe abysmal high IO during mkfs.xfs and fstrim inside the VM. A simple example: Step 1: Create 100G Thin disk Result 1: Disk occupies ~10M on storage Step 2: Format disk inside VM with mkfs.xfs Result 2: Disk occupies 100G on storage Changing the discard flag on the disk does not have any effect. Am I missing something? Best regards.

Recognizing Subinterfaces on oVirt Host
by Adam Mills 18 Jun '17

18 Jun '17

Hey Team! We are trying to nest some of our existing technology into the oVirt host as to not have to reinvent tooling, etc. Our proposal is to have a sub-interface on the 10G nic and place the VMs in that network. The network will be advertised to the Top of Rack switch via BGP. My current issue is that the oVirt web interface does not recognize the existence of an em1:1 interface of network. Given the above parameters, is there another way to accomplish what we are trying to do? Thanks in advance! Please refer to MS Paint style Visio for a visual [image: Inline image 1]
