Yes, libvirt does not support multiple hosts for gluster disk yet.

A workaround may be using DNS address that expose all hosts.

[ovirt-users] Changing the system resources of the pool VM

2018-11-08 Thread Hyung-Keun Kim 
Hi.

What I want to ask is simple.
System resource changes in the Pool VM do not seem to be supported by ovirt.
So let me ask you two questions.

1. Can you tell what the reason is? Are you related to the ovf file?

2. Is there any other way to use sub-templates? (Manual work is also fine)
 Is it possible to modify DB value only? If not, what else should I touch?

Waiting for experts to answer.
Thank you.

No, libgfapi access is disabled by default due to lack of HA

At this moment, for version mentioned below, this bug is actual?

more than a year has passed since that, versions updated
now qemu-kvm-ev-2.10.0-21.el7_5.7.1.x86_64
vdsm-4.20.43-1.el7.x86_64
glusterfs-server-3.12.15-1.el7.x86_64

I cannot reproduce it on my test install because I not configured 
storage fully (see my "set up ovirt 4.2 hyperconverged with glusterfs 
"storage network" over infiniband" post here)

But if it needs I may try.

hosted engine on that "engine" volume.

In cluster I want to use libgfapi gluster storage access method, but
when I import storages, created by installer at first step, VDSM mount
it on hosts with FUSE.

For Example
ovirtstor1.miac:/engine on
/rhev/data-center/mnt/glusterSD/ovirtstor1.miac:_engine type
fuse.glusterfs
(rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)

ovirtnode1.miac:/data on

fuse.glusterfs
(rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)

I see in config, And it is disabled (false)
[root@ovirtengine ~]# engine-config -a | grep -i libgf
LibgfApiSupported: false version: 3.6
LibgfApiSupported: false version: 4.0
LibgfApiSupported: false version: 4.1
LibgfApiSupported: false version: 4.2

Why? Its is needed to enable it by hand?

You can move to GlusterFS 4.1/5.0 with oVirt 4.3 as there's a
dependency change (gluster-gnfs that's removed) needed in spec to get
this working.

You can convert the 3 servers to run both gluster and compute by enabling
gluster service on cluster and reinstalling the hosts one at a time (to
ensure the gluster packages are installed and gluster is peer probed)
However, I don't know if there's a way to move the external engine to
hosted engine in this setup.

Can you provide output of gluster volume heal cps-vms-gfs info, and
the logs from  /var/log/glusterfs/glfsheal-cps-vms-gfs.log and the
brick logs from /var/log/glusterfs/bricks for this volume.

[ovirt-users] ovirt 4.2.7 nested not importing she domain

2018-11-08 Thread Gianluca Cecchi 
Hello,
I'm configuring a nested self hosted engine environment with 4.2.7 and
CentOS 7.5.
Domain type is NFS.
I deployed with

hosted-engine --deploy --noansible

All went apparently good but after creating the master storage domain I see
that the hosted engine domain is not automatically imported
At the moment I have only one host.

ovirt-ha-agent status gives every 10 seconds:
Nov 09 00:36:30 ovirtdemo01.localdomain.local ovirt-ha-agent[18407]:
ovirt-ha-agent
ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config.vm ERROR
Unable to identify the OVF_STORE volume, falling back to initial vm.conf.
Please ensure you already added your first data domain for regular VMs

In engine.log I see  every 15 seconds a dumpxml output ad the message:

2018-11-09 00:31:52,822+01 WARN

[ovirt-users] storage healing question

2018-11-08 Thread Dev Ops 
The switches above our environment had some VPC issues and the port channels 
went offline. The ports that had issues belonged to 2 of the gfs nodes in our 
environment. We have 3 storage nodes total with the 3rd being the arbiter. I 
wound up rebooting the first 2 nodes and everything came back happy. After a 
few hours I noticed that the storage was up but complaining about being out of 
sync and needing healing. Within the hour I noticed a VM had paused itself due 
to storage issues. This is a small environment, for now, with only 30 VM's. I 
am new to Ovirt so this is uncharted territory for me. I am tailing some logs 
and things look sort of normal and google is sending me down a wormhole. 

If I run "gluster volume heal cps-vms-gfs info" this number seems to be 
changing pretty regularly. Logs are showing lots of entries like this:

[2018-11-08 21:55:05.996675] I [MSGID: 114047] 
[client-handshake.c:1242:client_setvolume_cbk] 0-cps-vms-gfs-client-1: Server 
and Client lk-version numbers are not same, reopening the fds
[2018-11-08 21:55:05.997693] I [MSGID: 108002] [afr-common.c:5312:afr_notify] 
0-cps-vms-gfs-replicate-0: Client-quorum is met
[2018-11-08 21:55:05.997717] I [MSGID: 114035] 
[client-handshake.c:202:client_set_lk_version_cbk] 0-cps-vms-gfs-client-1: 
Server lk version = 1 

I guess I am curious what else should I be looking for? Is this just taking 
forever to heal? Is there something else I can run or I should do to verify 
things are actually getting better? I ran an actual heal command and it cleared 
everything for a few seconds and then the entries started to populate again 
when I did the info command.

We have more powerful and reliable mechanism, using host power management.

When power management is not available or fail, we have similar mechanism
using
sanlock, which like sanlock is using the host watchdog and communicating
with
other hosts via shared storage.

You can add a storage lease to HA VM. If the VM loose access to storage on
a host,
the system will start the VM on another host safely, even if the original
host is not
accessible or lost power.

Leases are also used to recover storage jobs (like copying volumes) when
the host
performing the copy became non-responsive. We can fence the storage job and
start
it safely on another host, without waiting for the original host to become
available again.

Can you explain what are the advantages of SBD fencing?

Hello,

did you evaluated shutting down vms via ansible or ovirt sdk?

[ovirt-users] Q: Guest shutdown from UPS power off signal with "virsh"

2018-11-08 Thread Andrei Verovski 
Hi !

I have a shell script running on all servers which intercepts power off signal 
(in case of power failure).

Is it safe to use direct KVM “virsh” commands to force guest shutdown on oVirt 
nodes, bypassing oVirt engine ?

“shutdown now” directly on oVirt nodes v4.2.6 takes an enormous amount of time 
because for whatever reason guests can’t be suspended. My nodes installed on 
CentOS 7.5, I’m not using pre-packaged version because each consecutive upgrade 
simply wipes out all my mods.

Thanks in advance.
Andrei


PS. I found this script to shutdown KVM guests:
***
#!/bin/bash

# 
https://ask.fedoraproject.org/en/question/8796/make-libvirt-to-shutdown-my-guests-not-suspend/

LIST_VM=`virsh list | grep running | awk '{print $2}'`
TIMEOUT=90
DATE=`date -R`
LOGFILE="/var/log/shutdownkvm.log"

if [ "x$activevm" =  "x" ]
then
exit 0
fi

for activevm in $LIST_VM
do
PIDNO=`ps ax | grep $activevm | grep kvm | cut -c 1-6 | head -n1`
echo "$DATE : Shutdown : $activevm : $PIDNO" >> $LOGFILE
virsh shutdown $activevm > /dev/null
COUNT=0

while [ "$COUNT" -lt "$TIMEOUT" ]
do
ps --pid $PIDNO > /dev/null
if [ "$?" -eq "1" ]
then
COUNT=110
else
sleep 5
COUNT=$(($COUNT+5))
fi
done

if [ $COUNT -lt 110 ]
then
echo "$DATE : $activevm not successful force shutdown" >> 
$LOGFILE
virsh destroy $activevm > /dev/null

[ovirt-users] Re: Network/Storage design

2018-11-08 Thread Josep Manel Andrés Moscardó 

Thanks for the tips,
I have set up one NIC on VLAN 1 for storage,  one NIC on VLAN 1 for 
Migration , 1 NIC on VLAN 1 for MGMT and one NIV on multiples VLANs for 
VM's.


Does it make sense or I will have routing issues for having multiple 
interfaces on the same VLAN with different IP's?


Thanks.

Hi,
thanks for the info.
So management network is used to deploy new images, but if I deploy the
VM's from PXE server, I guess this is not needed, right?

The storage network is clear.

And then the entworks for the VM's I guess that are the networks with
VLAN's, in my case, that will be used by the VM's. But, Which is the
network for migrating VM's from one host to the other? Does it need to
be non usable by the the VM's?

Thanks.

AFAIK it should be enabled by default in hyper-converged deployments.

Can you please grep your deployment logs for ENABLE_LIBGFAPI?

[ovirt-users] wrong vm disk size after uploading and attaching to VM

2018-11-08 Thread Jarosław Prokopowski 
Hi,

After uploading virutal machine disk to storage domain and attaching it to
virtual machine the disk size is shown in properties as 0 and the VM boots
to dracut complaining about the disk size.
The disk is "thin provision"

Device /dev/sda2 has size of 22528 sectors which is smaller than
corresponding PV size of 166746122 <16%20674%2061%2022>

Is there a way to fix that?

Thanks

hosted engine on that "engine" volume.


In cluster I want to use libgfapi gluster storage access method, but 
when I import storages, created by installer at first step, VDSM mount 
it on hosts with FUSE.


For Example
ovirtstor1.miac:/engine on 
/rhev/data-center/mnt/glusterSD/ovirtstor1.miac:_engine type 
fuse.glusterfs 
(rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)


ovirtnode1.miac:/data on 
/rhev/data-center/mnt/glusterSD/ovirtnode1.miac:_data type 
fuse.glusterfs 
(rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,max_read=131072)


I see in config, And it is disabled (false)
[root@ovirtengine ~]# engine-config -a | grep -i libgf
LibgfApiSupported: false version: 3.6
LibgfApiSupported: false version: 4.0
LibgfApiSupported: false version: 4.1
LibgfApiSupported: false version: 4.2

Why? Its is needed to enable it by hand?

Like as in this presentation?

[ovirt-users] Re: set up ovirt 4.2 hyperconverged with glusterfs "storage network" over infiniband

2018-11-08 Thread Mike Lykov

4. Gluster volumes are in strange state:




  When i try to create volume (storage->volumes->new), press "add 
bricks" - there is a similar drop-down box "Bricks Host" contains only 
"ovirtnode" names, not "ovirtstor" ib interfaces..
If I try to use it - It cannot finished with error like "This host not 
in trusted pool", its true - in trusted tool there is other interface.


What the right way to configure this?


Update:

I create network "storage", uncheck "required" and check "migrate" and 
"gluster" role.
Then i attach this network in "setup host networks" to hosts, interface 
ib0 (but it state is out-of-sync because different MTU in DC config and 
real host, see previous post)


But in engine.log I see this message:

2018-11-08 17:19:23,406+04 WARN 
[org.ovirt.engine.core.vdsbroker.gluster.GlusterVolumesListReturn] 
(DefaultQuartzScheduler7) [70a2eb8a] Could not associate brick 
'ovirtstor1.miac:/gluster_bricks/engine/engine' of volume 
'77d6bcb1-244d-4319-b3f0-e4eb73a9206c' with correct network as no 
gluster network found in cluster 'ea3c5a62-de76-11e8-9238-00163e062063'


Why "no gluster network found in cluster" ?
It is because it out-of-sync?
Network is UP in webui ...

[ovirt-users] Any plans for oVirt and SBD fencing (a.k.a. poison pill)

2018-11-08 Thread hunter86_bg 
Hello Community,

Do you  have any idea if SBD fencing mechanism  will be implemented in the 
nearest future?
It will be nice to be able to resset a host just like corosync/pacemaker 
cluster implementation.

[ovirt-users] Re: updating Spacewalk registered Enterprise hosts to 4.2.7

2018-11-08 Thread Matthias Leopold 

i think this is related to https://github.com/ansible/ansible/issues/46603
my colleague had similar problems with ansible 2.7.0 and yum, he told me 
his issue went away with ansible 2.7.1

would be nice if oVirt ansible could be updated to 2.7.1

thx

Hi,

just for the records:
I couldn't update my Spacewalk (2.6) registered Enterprise (CentOS)

Since this is only a test environment and i could easily switch the 
hosts to upstream repo mirrors I didn't do any further debugging. Maybe 
the Spacewalk server is too old...
