[ovirt-users] Official Hyperconverged Gluster oVirt upgrade procedure?
Hi Guys, Just wondering if we have an updated manual or whats the current procedure for upgrading the nodes in a hyperconverged ovirt gluster pool? Ie Nodes run 4.0 oVirt, as well as GlusterFS, and hosted-engine running in a gluster storage domain. Put node in maintenance mode and disable glusterfs from ovirt gui, run yum update?

[ovirt-users] Upgrade hosts/nodes from engine
Hi Guys, Quick question, I have my nodes on a bond-bridge-privateVlan setup, and my engine on a bond-bridge-publicVlan setup for remote monitoring. Understandably, the nodes are complaining that they are failing updates. (They're on a private vlan, and only configured with IP's in that vlan, the public vlan doesn't have IP's set on the hosts so they can pass it to VMs). Is there a way to have the engine do the updates on the node using its internet connection, like a proxy? For security reasons I like to have the nodes not publicly accessible, as we see hundreds if not thousands of ssh attempts, and root would probably be the most attacked account.

[ovirt-users] HostedEngine NIC setup files
Hi Guys, I have edited /etc/sysconfig/network-scripts/ifcfg-eth0 &1 for the various subnets we needed. Somewhere along the line, when the hosted-engine boots, eth1 comes up but eth0 does not. If I login using the upped interface and do an ifup eth0 it comes up. it is set to ONBOOT=yes in the config. I know with the nodes, that these files are overwritten on boot. Where should I be editing for the hosted-engine? Thanks, Hanson ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

[ovirt-users] How to manually restore backup
Hi Guys, Just wondering what the proper way to restore a backup to a hosted-engine? I've tried doing the deploy, then cleanup, and backup --mode=restore, but then engine-setup needs internet access. (which it doesn't have) Is there a way to restore the backup over the current data of a currently deployed new host? ie like a --mode=restore --option=force ? or is there another way to restore?

[ovirt-users] BSD Guests + oVirt
Hi Guys, Is there any optimizations for using FreeBSD 10.3 with ovirt? The guest OS works fine, however, the engine frequently lists the wrong status for the VM, like rebooting, booting etc. ovirt-guest-tools doesn't support freebsd from what I can find.

[ovirt-users] oVirt Gluster Hyperconverged problem
Hi Guys, I encountered an unfortunate circumstance today. Possibly an achillies heel. I have three hypervisors, HV1, HV2, HV3, all running gluster for hosted engine support. Individually they all pointed to HV1:/hosted_engine with backupvol=HV2,HV3... HV1 lost its bootsector, which was discovered upon a reboot. This had zero impact, as designed, on the VM's. However, now that HV1 is down, how does one go about replacing the original HV? The backup servers point to HV1, and you cannot readd the HV through the GUI, and the CLI will not readd it as it's already there... you cannot remove it as it is down in the GUI... Pointing the other HV's to their own storage may make sense for multiple instances of the hosted_engine, however it's nice that the gluster volumes are replicated and that one VM can be relaunched when a HV error is detected. It's also consuming less resources. What's the procedure to replace the original VM? ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[ovirt-users] hosted-engine and GlusterFS on Vlan help
Hi Guys,
I've converted my lab from using 802.3ad with bonding>bridged vlans to
one link with two vlan bridges and am now having traffic jumping to the
gateway when moving VM's/ISO/etc.
802.3ad = node1>switch1>node2
801.1q = node1>switch1>gateway>switch1>node2
I assume I've setup the same vlan style, though this time I used the gui
on the initial host install... setting up the vlans with their parent
being eth0.
Hosted-engine on deploy then creates ovirtmgmt on top of eth0.11 ...
Switch is tagged for vlans 10 & 11. Including a PVID of 11 for good
measure. (Gluster is vlan 11)
I'd expect the traffic from node to node to be going from port to port
like it did in 802.3ad, what have I done wrong or is it using the gui
initially?

Running iperf3 between node1 & node2, I can achieve almost 10gbps

So switching between port to port on the switch is working properly on

This must be a problem in the gluster settings? Where do I start

Tying yum update on node/hosts fails on gluster, and I'm leary on update
the repo to pull the newer gluster packages because of potential issues
of the other two hosts being on older glusters.

[ovirt-users] Adding host to hosted-engine /w gluster cluster. (On ovirt Node 4.2.1.1)
Hi Guys, I've a 3 machine pool running gluster with replica 3 and want to add two more machines. This would change to a replica 5... In ovirt 4.0, I'd done everything manually. No problem there. In ovirt 4.2, I'd used the wizard for the hosted-engine. It looks like the fourth node has been added to the pool but will not go active. It complains gluster isn't running (which I've not manually configured /dev/sdb for gluster). Host install+deploy fails. Host can go into maintenance w/o issue. (Meaning the host has been added to the cluster, but isn't operational) What do I need to do to get the node up and running proper with gluster syncing properly? Manually restarting gluster, tells me there's no peers and no volumes. Do we have a wizard for this too? Or do I need to go find the setup scripts and configure hosts 4 + 5 manually and run the deploy again?

Re: [ovirt-users] Adding host to hosted-engine /w gluster cluster. (On ovirt Node 4.2.1.1)
Hi Sahina, On the fourth node, I've found /var/log/glusterfs/rhev-data-center-mnt-glusterSD-ovirtnode1.core\:_engine.log ... is this the engine.log you're referring to or do you want one from the hosted engine? I actually do want to go replica 5. Most VM's it runs are small(1 Core,1gb Ram,8gb HDD) and HA is needed. I'd like a bigger critical margin than one node failing. As far as the repos, it's a straight the ovirtnode iso install, I think it's Node 4.2.0... which is yum updated to 4.2.1.1 When I installed 4.0 I'd installed on top of centos. This round I went straight with the node os because of simplicity in updating. I can manually restart gluster from cli, the peer and volume status show no peers or volumes. One thing of note, the networking is still as setup from the node install. I cannot change the networking info from the ovirt gui/dashboard. The host goes unresponsive and then another host power cycles it.

Re: [ovirt-users] HostedEngine with HA
Hi Carlos, If you're using shared storage across the nodes/hypervisors, the HostedEngine VM should already be HA. Sometimes this allows the engine to drop while restarting it on another node. Usually when this happens the rest of the nodes running VMs stay up, and things resync when the downed node comes back. IE the only one to lose pings is the Hosted-Engine. Unless ofcourse there were VM's on the same node, in which case, if they were HA VMs they will be restarted/resumed depending on your settings.

[ovirt-users] Grubx64.efi missing from boot partition
Hi Guys, We went to physically move a node and have found the node will not boot successfully anymore. The error coming up is :failed to open/ file not found: \EFI\BOOT\grubx64.efi This file is found in \EFI\centos\grubx64.efi. I have copied it to \EFI\BOOT\ and got the machine to boot, however, it has no working networking. Modifying /etc/sysconfig/ifcfg-xyzabz123 appropriately restored networking, however, the node is not able to be resumed/activated. This is probably because the blade reports the following interfaces: eno1, eno2, eno3, eno4 When originally deployed, they were eno1,eno2, eth0, eth1. The engine still sees the host as having the eno+eth combo. Any ideas guys?

[ovirt-users] Re: Gluster not synicng changes between nodes for engine
Ok,
So removing one downed node cleared all the non syncing issues.
In the mean time, when that one node was coming back, it seems to have
corrupted the hosted-engine vm.
Remote-Viewer nodeip:5900, the console shows:
Probing EDD (edd=off to disable)... ok
Doesn't matter which of the three remaining nodes try to launch the
engine, the engine comes up the same.
Had to set cluster to global maintenance, as the engine will keep trying
to start off different nodes.
I do have backups run nightly so I can restore engine vm, however, I
don't see a straight forward method of restoring the engine vm in a
hosted-engine gluster setup.
Can any of the redhat boys help?

[ovirt-users] Ovirt + Gluster : How do I gain access to the file systems of the VMs
Hi Guys, My engine has corrupted, and while waiting for help, I'd like to see if I can pull some data off the VM's to re purpose back onto dedicated hardware. Our setup is/was a gluster based storage system for VM's. The gluster data storage I'm assuming is okay, I think the hosted engine is hosed, and needs restored, but that's another thread. I can copy the raw disk file off of the gluster data domain. What's the best way to mount it short of importing it into another gluster domain? With vmware, we can grab the disk file and move it from server to server without issue. You can mount and explore contents with workstation. What do we have available to us for ovirt?

[ovirt-users] Re: Ovirt + Gluster : How do I gain access to the file systems of the VMs
Hi Guys, I've an answer... Here's how I did it... First, I needed kpartx ... so #apt-get install kpartx Then setup a loopback device for the raw hdd image #losetup /dev/loop4 [IMAGE FILE] #kpartx -a /dev/loop4 This allowed me to mount the various partitions included in the VM. There you can modify the configs, make backups etc. Thanks, Hanson On 06/19/2018 09:31 AM, Hanson Turner wrote: Hi Sahina, Thanks for your reply, I can copy the files off without issue.

[ovirt-users] HE + Gluster : Engine corrupted?

My when I VNC into my HE, All I get is:
Probing EDD (edd=off to disable)... ok
So, that's why it's failing the liveliness check... I cannot get the
screen on HE to change short of ctl-alt-del which will reboot the HE.
I do have backups for the HE that are/were run on a nightly basis.
If the cluster was left alone, the HE vm would bounce from machine to
machine trying to boot. This is why the cluster is in maintenance mode.
One of the nodes was down for a period of time and brought back,
sometime through the night, which is when the automated backup kicks,
the HE started bouncing around. Got nearly 1000 emails.
This seems to be the same error (but may not be the same cause) as
listed here:
https://bugzilla.redhat.com/show_bug.cgi?id=1569827
Thanks,
Hanson
