How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1
Note: Upgrading from 4.4.2 GA or later 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 4.4.7 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 4.4.7 (redeploy in case of already being on 4.4.7).
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.

Expected behavior when link of required VM networks down
by Gianluca Cecchi
Hello,
suppose I have a cluster with required VM logical network setup.
Suppose on hosts I have configured a bonding device with this logical
network mapped on it.
Suppose an active host for any reason loses the physical connectivity on
this bond (both links down or problems with new network config impacting
the bond, ecc)
So from the VMs point of view, those having a vnic on this logical network
will lose the connectivity, but I think they will not detect link down,
correct?
Is there any expected default action oVirt will take in respect of this
scenario or not?
Of course I expect to see events with messages about link down. But any
automatic action such as live migration of impacted VMs for example?
Any configurable one at oVirt level?
Thanks,
Gianluca

oVirt 4.2 how to upgrade
by Fedele Stabile
I have a 3 node oVirt 4.2.1 cluster,
i'm using a self-hosted engine architecture and
storage-engine is on a glusterfs replica 3
of the cluster.
The oldest CPU is SandyBridge family (E5-2609)
and incidentally it has connectivity problems with IPMI NIC,
but Hosted Engine HA is enabled and working.
May I reduce the glusterfs replica to 2 and use one of the 3 nodes to begin the installation of ovirt 4.4 on that node?

oVirt 4.4.5 - Windows Server 2003 VM Reboot problems
by simon＠justconnect.ie
Hi All,
I've had to migrate a Windows Server 2003 R2 VM from VMWare to oVirt which I have successfully managed to get running.
The problem I have is if I try to reboot from the OS I receive the following message after the VM shuts down but doesn't reboot:
"Exit message: Lost connection with qemu process."
Also any attempt to either shutdown or reboot from oVirt Manager has no effect.
I realize that this OS is not supported in the current oVirt version, but is there something I am missing to get it working 'unsupported' please?
Regards
Simon...

Disk (brick) failure on my stack
by Dominique D
yesterday I had a disk failure on my stack of 3 Ovirt 4.4.1 node
on each server I have 3 Bricks (engine, data, vmstore)
brick data 4X600Gig raid0. /dev/gluster_vg_sdb/gluster_lv_data mount /gluster_bricks/data
brick engine 2X1TB raid1 /dev/gluster_vg_sdc/gluster_lv_engine mount /gluster_bricks/engine
brick vmstore 2X1TB raid1 /dev/gluster_vg_sdc/gluster_lv_vmstore mount /gluster_bricks/vmstore
Everything was configured by the gui (hyperconverge and hosted-engine)
It is the raid0 of the 2nd server who broke.
all VMs were automatically moved to the other two servers, I haven't lost any data.
the host2 is now in maintenance mode.
I am going to buy 4 new SSD disks to replace the 4 disks of the defective raid0.
When I'm going to erase the faulty raid0 and create the new raid with the new disks on the raid controler, how do I add in ovirt so that they resynchronize with the other bricks data?

Is there a slack channel for oVirt project?
by Jesse Hu
Hi folks, Is there a slack channel for oVirt project? and is the #ovirt channel on irc.oftc.net server still active? I'd like to learn how oVirt project can be used for building IaaS platform, and whether oVirt community is active to provide support for questions. Thanks a lot.
