Fencing with oVirt 4.4 apc master switch
by Jeremey Wise
I use to have hand built CentOS+KVM + Gluster.
Moved to HCI oVirt controlled system and so far, been very happy with
stability and quality.
One feature that was working in old "hand build" version was fencing.
I have an old APC master switch AP9606. I use to have and use it for
master switch functions of nodes but sense replacement with oVirt it has
not worked. Here are setup notes and symptoms
IP: 172.16.100.2
Username: apc
Password: <blah>
Port 8 (it is an eight port unit)
Slot: <empty as I have no idea what is expects here I also input values
here but no change>
Error:
Test failed: WARNING:root:Parse error: Ignoring option 'agent' because it
does not have value ERROR:root:Unable to connect/login to fencing device
2020-10-11 11:28:50,885 ERROR: Unable to connect/login to fencing device
Questions:
1) Has anyone setup this with oVirt such that it uses apc master switch
2) Where is oVirt putting these logs / running this service. I assumed
oVirt engine running the services and so tried to find details and logs
here.

too many glitches while moving storage domain
by Jiří Sléžka
Hi,
today I started one not so common operation and I would like to share my
(not so good) experience.
I have 4 old Opteron G3 hosts which creates 1 DC with 1 cluster with 4.2
compatibility. Then I got 2 newer Intel based hosts which creates
separate DC and cluster. I use one shared FC storage with few LUNs for
all the stuff. Intel cluster is selfhosted with oVirt 4.4.2 where I
migrated original standalone oVirt 4.3.10 manager.
So I have 2 DCs, one with 4.2 and one with 4.4 compatibility.
Now the funny part... I had 2 LUNs connected to old 4.2 DC. My intention
was detach one of them and attach it to the new DC.
first pain was that some of vms had ther disks on both LUNs. It is
indicated late in the process and without hint which vms they are. So I
had to activate LUN in old DC and tried to find that vms (search string
in vms tab "Storage = one and Storage = two" seems not working). Ok, it
took two or three rounds... then, also late in the process there was
problem that one vm had previewed snapshot so another round with
activation of LUN in old DC... Then I was able detach and import LUN to
new DC. Nice, but with warning that LUN has 4.2 compatibility which will
be converted to 4.4 and there is no way back to connect it to old DC...
It is logical but very scary if something went wrong... but it did not
in my case :-)
LUN is connected in new DC. Now I had to import vms. Most vms were
imported ok but two of them were based on template wich resides on other
LUN. It was not indicated during detaching! It looks like I cannot move
template from storage to storage other way than through Export storage
(which I don't have at this moment) or through OVA export for which I
have not enough free storage space on hosts. Its a trap! :-) Btw. there
is no check for free space while starting export to OVA (template uses
preallocated disk). Exporting task still runs but there is no free space
at the host... and probably no way to cancel it from manager :-(
Ok, I had most of the vms imported. Last really strange thing is that I
lost one vm during import. It is not listed in VirtualMachines nor in VM
import tab on starage nor in Disk tab... that vm was an Aruba migration
tool and was imported from OVN image.
In fact there are two disks in Disk import tab, one of them has no
Alias/description and was created today around time I started work on
this migration. The second one has alias "vmdisk1" and is few months
older but I have no idea if it is the lost vm...
Sorry for long story, TL;DR version could be: There are glitches in some
(not so common) workflows...
Cheers,
Jiri

Nodes with a version and others with anothers

Re: Gluster volume not responding

Hi Simon,
I doubt the system needs tuning from network perspective.
I guess you can run some 'screen'-s which a pinging another system and logging everything to a file.

Thanks Strahil.
I have found between 1 & 4 Gluster peer rpc-clnt-ping timer expired messages in the rhev-data-center-mnt-glusterSD-hostname-strg:_pltfm_data01.log on the storage network IP. Of the 6 Hosts only 1 does not have these timeouts.
Fencing has been disabled but can you identify which logs are key to identifying the cause please.
It's a bonded (bond1) 10GB ovirt-mgmt logical network and Prod VM VLAN interface AND a bonded (bond2) 10GB Gluster storage network.
Dropped packets are seen incrementing in the vdsm.log but neither ethtool -S or kernel logs are showing dropped packets. I am wondering if they are being dropped due to the ring buffers being small.
Kind Regards
Shimme

Based on this one I make the following conclusions:
1. Issue is reoccuring
2. You most probably have a network issue
Have you checked the following:
- are there any ping timeouts between fuse clients and gluster nodes
- Have you tried to disable fencing and check the logs after the issue reoccurs
- Are you sharing Blackup and Prod networks ? Is it possible some backup/other production load in your environment to "black-out" your oVirt ?
- Have you check the gluster cluster's logs for anything meaningful ?

Moving VM disks from one storage domain to another. Automate?
by Green, Jacob Allen /C
I am looking for an automated way, via Ansible to move a VM disk from one storage domain to another. I found the following, https://docs.ansible.com/ansible/latest/modules/ovirt_disk_module.html and while it mentions copying a VM disk image from one domain to another it does not mention a live storage migration. Which is what I am looking to do. I want to take roughly 100 VMs and move their disk images from one domain to another that is available to the datacenter in some automated/scripted fashion. I am just curious if anyone out there has had to do this and how they tackled it. Or perhaps I am missing some easy obvious way, other than clicking all the disks and clicking move. However from the looks of it, if I did click all the disk and selected move, it appears RHV tries to do them all at once, which is probably not ideal, I would like it to move the disks in a serial One after another fashion, to conserve throughput and IO.
I also did not see anything on Ansible galaxy or the ovirt github that would do this.
Thank you.

Current Version: 4.3.4.3-1.el7 - Although we are keen to upgrade, we need stability for this production environment before doing so.
This Data Center has 2 x 3 Node clusters (Admin & Platform) which each have a 3 Replica Gluster configuration which is not managed by the self hosted ovirt engine.
Any assistance is appreciated.

Hi all,
For a group of users added to ovirt through AD, which role should one add to an ISO for the group to be able to select an ISO when creating VM's in the VM portal?
Thanks.

[ANN] oVirt 4.4.3 Fourth Release Candidate is now available for testing
by Lev Veyde
oVirt 4.4.3 Fourth Release Candidate is now available for testing
The oVirt Project is pleased to announce the availability of oVirt 4.4.3
Fourth Release Candidate for testing, as of October 8th, 2020.
This update is the third in a series of stabilization updates to the 4.4
series.
How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1
Note: Upgrading from 4.4.2 GA should not require re-doing these steps, if
already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only
required to be done once.
Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> -
Host enter emergency mode after upgrading to latest build
If you have your root file system on a multipath device on your hosts you
should be aware that after upgrading from 4.4.1 to 4.4.3 you may get your
host entering emergency mode.
In order to prevent this be sure to upgrade oVirt Engine first, then on
your hosts:
1.
Remove the current lvm filter while still on 4.4.1, or in emergency mode
(if rebooted).
2.
Reboot.
3.
Upgrade to 4.4.3 (redeploy in case of already being on 4.4.3).
4.
Run vdsm-tool config-lvm-filter to confirm there is a new filter in
place.
5.
Only if not using oVirt Node:
- run "dracut --force --add multipath” to rebuild initramfs with the
correct filter configuration
6.
Reboot.
