[Ovirt 4.0.6] Suggestion required for Network Throughput options
by TranceWorldLogic . 04 Jul '17

04 Jul '17

Hi, To increase network throughput we have changed txqueuelen of network device and bridge manually. And observed improved throughput. But in ovirt I not see any option to increase txqueuelen. Can someone suggest me what will be the right way to increase throughput ? Note: I am trying to increase throughput for ipsec packets. Thanks, ~Rohit

iSCSI multipathing setup troubles
by Matthias Leopold 03 Jul '17

03 Jul '17

hi, i'm trying to use iSCSI multipathing for a LUN shared by a Hitachi SAN. i can't figure out how this is supposed to work, maybe my setup isn't applicable at all... our storage admin shared the same LUN for me on two targets, which are located in two logical networks connected to different switches (i asked him to do so). on the oVirt hypervisor side there is only one bonded interface for storage traffic, so i configured two VLAN interfaces located in these networks on the bond interface. now i create the storage domain logging in to one of the targets connecting through its logical network. when i try to create a "second" storage domain for the same LUN logging in to the second target, oVirt tells me "LUN is already in use". i understand this, but now i can't configure an oVirt "iSCSI Bond" in any way. how is this supposed to work? right now the only working setup i can think of would be an iSCSI target that uses a redundant bond interface (with only one IP addresss) to which my hypervisors connect through different routed networks (using either dedicated network cards or vlan interfaces). is that correct? i feel like i'm missing something, but i couldn't find any examples for real world IP setups for iSCSI multipathing. thanks for explaining matthias

download/export a VM image
by aduckers 03 Jul '17

03 Jul '17

Running a 4.1 cluster with FC SAN storage. I’ve got a VM that I’ve customized, and would now like to pull that out of oVirt in order to share with folks outside the environment. What’s the easiest way to do that? I see that the export domain is being deprecated, though I can still set one up at this time. Even in the case of an NFS export domain though, it looks like I’d need to drill down into the exported file system and find the correct image based on VMID (I think..). Is there a simple way to grab a VM image? Thanks

add fourth full gluster node and remove arbiter: ovirt 4.1 with hosted engine
by yayo (j) 03 Jul '17

03 Jul '17

Hi at all, we have a 3 node cluster with this configuration: ovirtzz 4.1 with 3 node hyperconverged with gluster. 2 node are "full replicated" and 1 node is the arbiter. Now we have a new server to add to cluster then we want to add this new server and remove the arbiter (or, make this new server a "full replicated" gluster with arbiter role? I don't know) Can you please help me to know what is the right way to do this? Or, Can you give me any doc or link that explain the steps to do this? Thank you in advance!

Re: [ovirt-users] Recovering hosted-engine

Hi Didi Fair enough. If I'm in this situation..... I have 3 hosts with 6 production VMs. The hosted-engine VM is completely toast and not recoverable. However I have a backup of the hosted-engine database (do I need anything else). Is it possible to build a new VM, import the backup of the previous hosted-engine database and reconnect the storage domains and VMs in their running state without any VMs experiencing an outage? The URL http://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restorin… looks to be longer now. I'll review, test and see if this will give me what I'm looking for. The broken link still seems to be broken.

Virtual Machine looses connectivity with no clear explanation
by FERNANDO FREDIANI 03 Jul '17

This is a multi-part message in MIME format. --------------CA6FA101A23C7121C82BF9C5 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit I have a rather strange issue which is affecting one of my last deployed Hypervisors. It is a CentOS 7 (not a oVirt Node) which runs only 3 Virtual Machines. One of these VMs have a reasonable output traffic at peaks (500 - 700Mbps) and the hypervisor underneath is connected to the switch via a bonding (mode=2) which in turn creates bond0.XX interfaces which are connected to different bridges for each network. The VM in question is connected to bridge "ovirtmgmt". When the problem happens the VM stops passing traffic and cannot reach even the router or other VMs in the same Layer 2. Seems the bridge stop passing traffic for that particular VM. Other VMs work fine since they were created. When this problem happens I just need to go to its Console and run a reboot (Ctrl-Alt-Del), don't even need to Power Off and Power On again using oVirt Engine. I have even re-installed this VMs operating system from scratch but the problem persists. Have also changed the vNic mac address in the case (already check) of conflicted mac addresses somewhere in that Layer 2. Last, my hypervisor machine (due a mistake) has been running with SElinux disabled, not sure if it could have anything to do with this behavior. Anyway, anyone has ever seen any behavior like that ?

Gluster issue with /var/lib/glusterd/peers/<ip> file
by Mike DePaulo 03 Jul '17

03 Jul '17

Hi everyone, I have ovirt 4.1.1/4.1.2 running on 3 hosts with a gluster hosted engine. I was working on setting up a network for gluster storage and migration. The addresses for it will be 10.0.20.x, rather than 192.168.1.x for the management network. However, I switched gluster storage and migration back over to the management network. I updated and rebooted one of my hosts (death-star, 10.0.20.52) and on reboot, the glusterd service would start, but wouldn't seem to work. The engine webgui reported that its bricks were down, and commands like this would fail: [root@death-star glusterfs]# gluster pool list pool list: failed [root@death-star glusterfs]# gluster peer status peer status: failed Upon further investigation, I had under /var/lib/glusterd/peers/ the 2 existing UUID files, plus a new 3rd one: [root@death-star peers]# cat 10.0.20.53 uuid=00000000-0000-0000-0000-000000000000 state=0 hostname1=10.0.20.53 I moved that file out of there, restarted glusterd, and now gluster is working again. I am guessing that this is a bug. Let me know if I should attach other log files; I am not sure which ones. And yes, 10.0.20.53 is the IP of one of the other hosts. -Mike

Other portals work, user portal experiences console errors
by Sophia Valentine 03 Jul '17

03 Jul '17

Hi all! I installed the nightly from the repo on CentOS 7.0. I currently have an issue where visiting the user portal triggers the following errors in the browser console. I believe that I will need to compile the engine from source due to the current source being compacted, thus obscuring the stacktrace. If that is needed, can I generate an RPM with the debug build I create (might need some help with this, if that's okay)? I'm hoping it's a "known error" and that there's a simple fix. Would love to get to the bottom of this! Thanks.

Gluster storage network not being used for Gluster
by Mike DePaulo 03 Jul '17

03 Jul '17

Hi, I configured a "Gluster storage" network, but it doesn't look like it is being used for Gluster. Specifically, the switch's LEDs are not blinking, and the hosts' "Total Tx" and "Total Rx" counts are not changing (and they're tiny, under 1 MB.) The management network must still be being used. I have 3 hosts running oVirt Node 4.1.x. I set them up via the gluster hosted engine. The gluster storage network is 10.0.20.x. These are the contents of /var/lib/glusterd/peers: [root@centerpoint peers]# cat 8a83fddd-df7e-4e3b-9fc7-ca1c9bf9deaa uuid=8a83fddd-df7e-4e3b-9fc7-ca1c9bf9deaa state=3 hostname1=death-star.ad.depaulo.org hostname2=death-star hostname3=192.168.1.52 hostname4=10.0.20.52 [root@centerpoint peers]# cat b6b96427-a0dd-47ff-b3e0-038eb0967fb9 uuid=b6b96427-a0dd-47ff-b3e0-038eb0967fb9 state=3 hostname1=starkiller-base.ad.depaulo.org hostname2=starkiller-base hostname3=192.168.1.53 Thanks in advance, -Mike

vdsm changing disk scheduler when starting, configurable?
by Darrell Budic 03 Jul '17

03 Jul '17

It seems vdsmd under 4.1.x (or something under it’s control) changes the disk schedulers when it starts or a host node is activated, and I’d like to avoid this. Is it preventable? Or configurable anywhere? This was probably happening under earlier version, but I just noticed it while upgrading some converged boxes today. It likes to set deadline, which I understand is the RHEL default for centos 7 on non SATA disks. But I’d rather have NOOP on my SSDs because SSDs, and NOOP on my SATA spinning platters because ZFS does it’s own scheduling, and running anything other than NOOP can cause increased CPU utilization for no gain. It’s also fighting ZFS, which tires to set NOOP on whole disks it controls, and my kernel command line setting. Thanks, -Darrell

vdsm (4.1) restarts glusterd when activating a node, even if it's already running
by Darrell Budic 03 Jul '17

03 Jul '17

Upgrading some nodes today, and noticed that vdsmd restarts glusterd on a node when it activates it. This is causing a short break in healing when the shd gets disconnected, forcing some extra healing when the healing process reports “Transport Endpoint Disconnected” (N/A in the ovirt gui). This is on a converged cluster (3 nodes, gluster replica volume across all 3, ovirt-engine running elsewhere). Centos 7 install, just upgraded to Ovirt 4.1.2, running cluster 3.10 from the Centos SIG. The process I’m observing: Place a node into maintenance via GUI Update node from command line Reboot node (kernel update) Watch gluster heal itself after reboot Activate node in GUI gluster is completely stopped on this node gluster is started on this node healing begins again, but isn’t working “gluster vol heal XXXX info” reports this node’s information not available because “Transport endpoint not connected”. This clears up in 5-10 minutes, then volume heals normally Someone with a similar setup want to check this and see if it’s something specific to my nodes, or just a general problem with the way it’s restarting gluster? Looking for a little confirmation before I file a bug report on it. Or a dev want to comment on why it stops and starts gluster, instead of a restart which would presumably leave the brick processes and shd running and not causing this effect? Thanks, -Darrell

oVirt Node update not updating kernel, glibc, etc
by Mike DePaulo 02 Jul '17

02 Jul '17

Hi, I installed 3 ovirt 4.1.1 nodes in early May. Today used oVirt's webgui to update ("Upgrade") 2 of them. They are both reporting oVirt Node 4.1.2 & vdsm-4.19.15-1.el7.centos now. However, it appears that the kernel was not updated: [root@death-star peers]# uname -a Linux death-star 3.10.0-514.16.1.el7.x86_64 #1 SMP Wed Apr 12 15:04:24 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux And neither was glibc The installed version is still 2.17-157.el7_3.1 rather than 2.17-157.el7_3.4 . The following lines were appended to /var/log/yum.log: Jul 01 18:47:49 Installed: ovirt-node-ng-image-4.1.2-1.el7.centos.noarch Jul 01 18:50:27 Installed: ovirt-node-ng-image-update-4.1.2-1.el7.centos.noarch Jul 01 18:50:27 Erased: ovirt-node-ng-image-update-placeholder-4.1.1.1-1.el7.centos.noarch Thanks in advance, -Mike

Re: [ovirt-users] [ovirt-devel] problem about vm in ovirt node can ping node, but cannot ping gateway or the third host in LAN
by Edward Haas 01 Jul '17

01 Jul '17

If I understood correctly, you are using a nested solution where the node is itself a VM. If this is the case, you may have a security feature active on the physical host/node. In oVirt we have the default filter which allows only a single source mac to exit the vNIC, but you disabled it. I guess you should have something similar on the upper node. Please note that such topics fit the user list, not devel. Thanks, Edy.
