both are okay, in case of a host in "up" status, it will go down during
the playbook execution, but vms will continue to run without any
downtime. Host will recover and go up once certificates will be
successfully renewed.
This is an emergency procedure, the best solution to renew a certificate
on a running host is to put the host into maintenance and renew certs
via UI.

After attaching the Storage domain, the VMs are disappeared from the VM import
by aminur.rahman＠iongroup.com
Hi,
We're noticing some weird issue while re-attaching the storage domain. After re-attach the storage domain, some VMs are completely missing from the VM Import. Before detaching the storage domain, all the VMs were shutdown gracefully.
I also noticed some disks are exists with no Alias under the disk import on the storage domain and I can't import those disks. Its failed to register the disk with <UNKONOWN> error.
We're using Ovirt 4.2 with multiple Dell hosts in the cluster and Compellent SAN with iSCSI volumes.
Please kindly advise if I am missing anything before detach the storage domain.
Thanks

Installing oVirt is not so easy as stated, i am struck up in FQDN resolution , i have this FQDN (vmanager.headache.com) resolve to ip 10.1.1.6 in DNS within the network,additionally i also input this entries into /etc/hosts file. while installing ( may be 8 times ) ,i am struck up with error " he_fqdn proposed for the engine VM resolves on this host " . The network is using vlan ip, the host is already installed bare metal into cisco c240-m5 with RH virtualization ver 4.4 ,its installed on IP :10.1.1.5. the problem is with installing the self hosted engine (ovirt).
the vlan are like eno2.vlan7 and eno2.vlan7.1
/etc/hosts

Re: oVirt 4.4.x step-by-step procedure to renew expired oVirt certificates
by Nathanaël Blanchet
Hello,
If you refer to:
1. engine apache certificate expiration ("PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException:) to
access to ovirt console.
=> engine-setup --offline
2. hosts certificate expiration?
=> https://access.redhat.com/solutions/3532921
I also wrote a playbook to do so there:
https://galaxy.ansible.com/natman/ovirt_renew_certs
In this case, don't forget to renew certificate with UI (into
maintenance) when host is reponding, otherwise you may enconter
issues with console or live migration or other SSL related stuff.
tested and approved.

Cant fix network
by David Johnson
Good afternoon all,
Welcome to the third part of my trilogy of disaster recovery woes. Much of
my woe is self inflicted, but I have learned enough from this that I now
know how to ask the right question about the original problem that got me
here.
After reinstalling the engine from the ground up, ovirt immediately
recognized the first host (yay) whose network configuration I had manually
fixed on the host console.
I removed the host from the engine, stripped its system down to the bare
OS, then attempted to reinstall ovirt.
Apparently the original network configuration is still saved on the host,
because reinstall kicks the host off of the management network, replacing
the good configuration that I just made on the host with the bad one that
was the original cause of my heartache.
What is wrong with this configuration is that the storage network is on a
10 gbit sfp+ physical network, isolated from the 1 gbit ovirtmgt network
with RJ12 connectors. There is no way to bridge the two networks
Here is the original (bad) configuration:
[image: image.png]
Here is the corrected configuration. Note that it wont let me connect to
the network. it's frustrating because I know that the engine is not
communicating with the host, and I can map out the fix here, but I can't
save it.
[image: image.png]
It will not allow me to remove the host or switch the host to inoperable or
maintenance mode.
Please advise.

1 Unsynced Entry
by Abe E
I am having an issue on 1 single node where it is reporting 1 unsynced entry and it is not healing by itself or by force.
In the glustershd.log it is reporting the following:
W [MSGID: 114031] [client-rpc-fops_v2.c:2620:client4_0_lookup_cbk] 0-data-client-2: remote operation failed. [{path=<gfid:a8769008-3658-400f-b3ba-c0df40e648a7>}, {gfid=a8769008-3658-400f-b3ba-c0df40e648a7}, {errno=2}, {error=No such file or directory}]
I assume if it was missing it would look to other nodes for it but I understand from this that even other nodes do not have it?

OVIRT Package Upgrade Interrupted
by Abe E
It seems I haven't learned my lesson with upgrading via GUI.
For some reason my server crashed during use of the GUI Upgrade method and it looks like maybe it did not complete or the like.
3NodeGluster
I then noticed that I had actually upgrading a single node to the 4.5.1 Testing Version, that being said my glusterfs for this node is on 10.2 while other nodes are on 10.1.
Is there a "cleaner" way of reverting the upgrade?
I assume there are other packages that may have been upgraded that should be reverted.

Dead agent
by Valerio Luccio
Hello all,
I have an ovirt 4.4 installation whit self-hosted engine where the agent
seems to have died. The VMs are still running, so I assume that the
engine itself is still running (is this a wrong assumption ?). Can I
restart the agent without affecting the running VMs, that is how will
restarting the agent affect the running VMs ? If I can restart the
agent, what's the correct way of doing it ?
Thanks,
