[ovirt-users] Re: RHEL 7.5 as an oVirt host - missing packages

2018-06-16 Thread jasonmicron
Sorry, I hate to be "that guy", but does no one here seem to care that both the 
repositories and documentation are wrong for installing oVirt on RHEL 7.5?  
Either the documentation is wrong, or the RHEL repos require updating.  

One or the other is true, and I don't know enough about the oVirt support 
structure to know where to submit the appropriate bug report.  I'm happy to do 
so, but I need input from the community here.

I went ahead and installed the Satellite repo, but there is also an install 
problem with the gluster-server package - it never installs.  I had to manually 
install it and manually launch the daemon and enable it (glusterd).

To see this yourself:

1) Have an existing functional oVirt environment
2) Install RHEL 7.5 onto a new host from an ISO and subscribe it to Red Hat's 
repos
3) Configure the rhel-7-server-rpms, rhel-7-server-optional-rpms and 
rhel-7-server-extras-rpms repos
4) Try to add the new host to the oVirt cluster
5) See the failure
6) Configure the rhel-7-server-satellite-tools-6.3-rpms repo on the RHEL host
7) Try to add the host again
8) See it fail again
9) Install the gluster-server package onto the RHEL 7.5 host
10) Enable the glusterd service and start it
11) Try YET AGAIN to add the RHEL 7.5 host to the cluster
12) Success

So I say again - either the documentation is wrong, or Red Hat's repos require 
an update (specifically the Extras repo).

[ovirt-users] ovirt upgrade 4.1 -> 4.2: host bricks down

2018-06-16 Thread Alex K
Hi all,

I have a ovirt 2 node cluster for testing with self hosted engine on top
gluster.

The cluster was running on 4.1. After the upgrade to 4.2, which generally
went smoothly, I am seeing that the bricks of one of the hosts (v1) are
detected as down, while the gluster is ok when checked with command lines
and all volumes mounted.

Below is the error that the engine logs:

2018-06-17 00:21:26,309+03 ERROR

Apart from this everything else is operating normally and VMs are running
on both hosts.

Any idea to isolate this issue?

Thanx,
Alex

[ovirt-users] Gluster not synicng changes between nodes for engine

2018-06-16 Thread Hanson Turner

Hi Guys,

I've got 60 some odd files for each of the nodes in the cluster, they 
don't seem to be syncing.


Running a volume heal engine full, reports successful. Running volume 
heal engine info reports the same files, and doesn't seem to be syncing.


Running a volume heal engine info split-brain, there's nothing listed in 
split-brain.


Peers show as connected. Gluster volumes are started/up.

Hosted-engine --vm-status reports :
The hosted engine configuration has not been retrieved from shared 
storage. Please ensure that ovirt-ha-agent is running and the storage 
server is reachable.


This is leaving the cluster in an engine down with all vm's down state...

Thanks,

[ovirt-users] ovirt 4.2 and hugepages

2018-06-16 Thread Gianluca Cecchi
A part from configuring high performance vm, that gives me no high
availability.
Can I allocate huge pages
using vdsm-hook-hugepages-4.19.31-1.el7.centos.noarch

it seems that after updating an environment to 4.2 I'm not able to start a
VM configured with the custom property

I get

Th ehost x did not satisfy internal filter HugePages because there are
not enough free huge pages to run the VM

But on host I have

# cat /proc/meminfo | grep -i huge
AnonHugePages: 0 kB
HugePages_Total:   6
HugePages_Free:6
HugePages_Rsvd:0
HugePages_Surp:0
Hugepagesize:   2048 kB
#

and the custom property is configured to allocate 8200 huge pages to the
guest

The gropu configured in sysctl.d/10-hugepages.conf is

vm.hugetlb_shm_group = 36

Do I have to set anything in /etc/securily/limits.d/ for qemu user?

Thanks In advance,

Gainluca
