[ovirt-users] Re: [ANN] oVirt 4.3.5 Third Release Candidate is now available for testing

[Strahil]

I've mentioned it into the bug that tracks gluster6 integration with oVirt -> 
https://bugzilla.redhat.com/show_bug.cgi?id=1693998

At that time, oVirt was still not using gluster v6 , so I didn't open a 
separate bug.

As I'm currently on the go, I can open a bug with more details in Monday.

[ovirt-users] VM IPsec network performance

[TranceWorldLogic .]

Hi,

I have enable multi-queue feature on nic card and I am getting normal
throughput as 26 Gbps.
But when I am trying throughput test with IPsec I am getting only max
1.5Gbps. After looking at CPU usages, it is free more than 50%, I am not
getting why low throughput in ipsec case.

Below are my trial:
2nd, I tried to distribute multi-queue interrupt on mult-cpu but got same
result.
3rd, I tried nic passthrough and enable RSS, I got good throughput and CPU
usages.

Please help me to understand how to increase vnet performance for VM. And
also suggest me about ovirt setting.
I have also seen some presentation in google around virtio-crypto but as I
am using Guest and Host OS as centos 7.3, I can't use virtio-crypto device.

Thanks,
~Rohit

Ok,  the packages and versionlocks are not shown, because the were  disabled by 
default on a ovirt node.

The next command makes the possible to see the  locked but potential upgradable 
packages (up to 128).

# yum --enablerepo=base --enablerepo=updates --enablerep=extras 
--enablerepo=epel  versionlock status

Upgrade, or not upgrade? This is the question, Didi says wait for next release.
Another thing is the  „oVirt Node Master - Latest master, experimental“.

If it's so urgent for you, or if you need to test something before
production, you can always try latest jenkins build:

https://jenkins.ovirt.org/job/ovirt-node-ng-image_4.3_build-artifacts-el7-x86_64/

Anyway, since 4.3 is out for some months now, I'd definitely not
recommend master branch for 4.3 setups that hope for some stability
(even if trying jenkins builds). I am pretty certain that it already
diverted from 4.3 quite a lot.

Well, with 4.1 and 4.2 I just enabled the CentOS repos and did the upgrades, 
there was no versionlock.

btw, on my engine I see a few versionlocks too.

...snip
# yum versionlock list
Loaded plugins: fastestmirror, versionlock
ovirt-engine-webadmin-portal-4.3.4.3-1.el7.noarch
ovirt-engine-ui-extensions-1.0.5-1.el7.noarch

ovirt-engine-tools-4.3.4.3-1.el7.noarch
ovirt-engine-extension-aaa-jdbc-1.1.10-1.el7.noarch
versionlock list done
snap...

That makes me guess that there could be some important locks on ovirt node and 
makes me hesitate to unconditionally disable them. I wonder how 4.3 behaves 
when installed on top of CentOS (not ovirt node).

[ovirt-users] Re: Cannot inquire Lease

[suporte]

After empty the image file, the data center came up and I was able to remove 
the VM disk on oVirt Web GUI. 
What is the best practice to stop gluster to fill all the disk? 
When I had a new storage gluster domain in advanced parameters I usually 
configure it like this: 
Warning Low Space Indicator (%): 20 
Critical Space Action Blocker (GB): 5 
Warning Low Confirmed Space Indicator (%): 20 

is this the best way?

Hm ... Removing it from the gluster but not inside oVirt can cause a lot of 
headaches. 
Can you find that image in oVirt Storage -> Disks 

Sadly , you got no other option and the optimal approach would be to take the 
deletion from oVirt UI/API before the storage gets full. 


Ovirt has the option to notify you in advance.

[ovirt-users] Re: Cannot inquire Lease

[Strahil]

It looks OK to me , but I'm no expert in that.

In such case you will have  5 GB as a reserve, which you can reduce, just to be 
able to delete some data (in this case VM).
The question that comes to my mind is - did you receive any warning by oVirt 
that gluster is almost full ?

[ovirt-users] Re: Ovirt Hyperconverged Cluster

[Edward Berger]

You might be hitting a multipath config issue.

On a 4.3.4. node-ng cluster I had a similar problem.  spare disk was on
/dev/sda  (boot disk was /dev/sdb)

I found this link
https://stackoverflow.com/questions/45889799/pvcreate-failing-to-create-pv-device-not-found-dev-sdxy-or-ignored-by-filteri

which led me to lsblk /dev/sda and then add the "displayed wwid" to the
multipath.conf blacklist.
after restarting multipathd, I was able to use the cockpit wizard to
install gluster on /dev/sda.

I just notice a lots of messages about ". Cannot inquire Lease .." 
scrolling down. 
But scrolling down deeper I found this message "Critical, Low disk space.

But was to late 

It should stop at 5 GB of free space, according with "Critical Space Action

or not?

After empty the image file, the data center came up and I was able to remove 
the VM disk on oVirt Web GUI. 
What is the best practice to stop gluster to fill all the disk? 
When I had a new storage gluster domain in advanced parameters I usually 
configure it like this: 
Warning Low Space Indicator (%): 20 
Critical Space Action Blocker (GB): 5 
Warning Low Confirmed Space Indicator (%): 20 

is this the best way?

Hm ... Removing it from the gluster but not inside oVirt can cause a lot of 
headaches. 
Can you find that image in oVirt Storage -> Disks 

Sadly , you got no other option and the optimal approach would be to take the 
deletion from oVirt UI/API before the storage gets full. 


Ovirt has the option to notify you in advance.

I just empty a big image here 
/rhev/data-center/mnt/glusterSD/ node2.abc.pt 
:_data/0a19a375-77cb-47e5-af12-7b5451e6fa53/images

and everything looks like it's working again.

Assunto: [ovirt-users] Cannot inquire Lease 

Hi, 

The glusterfs domain disk data master is full and the volume is down. 
I have this error: 
VDSM NODE2 command SpmStatusVDS failed: Cannot inquire Lease(name='SDM', 
path=u'/rhev/data-center/mnt/glusterSD/ node2.abc.pt 
:_data/0a19a375-77cb-47e5-af12-7b5451e6fa53/dom_md/leases', offset=1048576): 
(2, 'Sanlock get hosts failure', 'No such file or directory') 

Cannot delete de domain because is the data master. 
Version 4.3.4.3 -1.el7 

What can I do? 


Thanks 

José

[ovirt-users] Re: disk description

[Dmitry Filonov]

Sorry, somehow your message went to spam and I missed it.
Disk is not encrypted. But I wanna change some disk details (as simple as
description) for the disk that is not attached to any VMs.
Just a disk under oVirt.
Exactly the the bug Gianluca was talking about.
