oVirt nVidia vGPU driver questions
by femi adegoke 17 Apr '19

17 Apr '19

I'm on oVirt 4.2.6. 1) If I have a Tesla P4 (Pascal) GPU (non-GRID), do I use nVidia vGPU driver for RHEL KVM 6.2 or the Linux KVM vGPU 6.2 driver? 2) If I have a Grid K1 or K2, I assume the correct driver would be GRID 4.7? 3) Must the vGPU driver be installed on the host & in the vm? 4) Must the vGPU driver be installed first before I can run "yum -y install vdsm-hook-vfio-mdev”

Gluster suggestions
by Magnus Isaksson 16 Apr '19

16 Apr '19

Hello I would like some suggestions on what type of solution with Gluster i should use. I have 4 hosts with 3 disks each, i want to user as much space as possible but also some redundancy, like raid5 or 6 The 4 hosts are running oVirt on CentOS 7 I have 2 clusters due to some licensing issues, so i cant use ovirts setup of gluster Today i have set it up as follows Type: Disperse Number of Bricks: 1 x (8 + 4) = 12 So i have 3 bricks per host (one brick per disk) But this setup is not working very well, as soon as i get some traffic on the volume this start to fail on the ovirt nodes, loosing connection etc. All hosts are connected via 10G interface So any suggestions on how i would set this up as best is much appreciated. Regards Magnus Isaksson

active directory: how to replace user@corp.mydomain.com with user@mydomain.com

Gluster arbiter volume storage domain - change
by Leo David 16 Apr '19

16 Apr '19

Hi Everyone, I have wrongly configured the main gluster volume ( 12 identical 1tb ssd disks, replica 3 distributed-replicated, across 6 nodes - 2 per node ) with arbiter one. Oviously I am wasting storage space in this scenario with the arbiter bricks, and I would like to convert the volume to non-arbitrated one, so having all the data evenly spreaded across all the disks. Considering the the storage is being used by about 40 vms in production, what would it be the steps, or is there any chance to change the volume type to non-arbitrated on the fly and then rebalance ? Thank you very much !

Even if you run gluster outside of oVirt, you are using the disperse volume as storage domain? For a supported config, you can create a distributed-replica+arbiter gluster volume. Since you have 12 disks, you can use a 5 x 3 (arbiter) setup, where a disk is partitioned to multiple arbiter bricks, something like this (c11,c12, a31, a32 are arbiter bricks) : a1 b1 c11 a2 b2 c12 b3 c13 d1 a31 c2 d2 a32 c3 d3 > > //Magnus > > > ________________________________ > From: Sahina Bose <sabose(a)redhat.com> > Sent: 16 April 2019 10:55 > To: Magnus Isaksson > Cc: users > Subject: Re: [ovirt-users] Gluster suggestions > > On Tue, Apr 16, 2019 at 1:42 PM <magnus(a)vmar.se> wrote: > > > > Hello > > > > I would like some suggestions on what type of solution with Gluster i should use. > > > > I have 4 hosts with 3 disks each, i want to user as much space as possible but also some redundancy, like raid5 or 6 > > The 4 hosts are running oVirt on CentOS 7 > > I have 2 clusters due to some licensing issues, so i cant use ovirts setup of gluster > > I did not quite get this - are you saying you can have only 2 nodes in > one cluster? > > > > > Today i have set it up as follows > > Type: Disperse > > Number of Bricks: 1 x (8 + 4) = 12 > > Disperse volumes are not supported with oVirt.
