Can self-hosted engine setup v4.1 used in production environment

Latest response

Hi,

We are trying out installation of self-hosted engine setup RHV v4.1 in one of our lab servers and facing few stability issues listed below:
1) While adding an existing VM present on the other host to a self-hosted RHEV-M using RHV version 4.1 observed that manager crashed.
2) While doing a self-hosted engine setup, after configuring and running the manager the script is failing also sometimes services like ha-agent & ha-broker are not running.
3) In the RHEV-M GUI the data center is shown as "Uninitialized" and it is not automatically detecting its own host.

Please let us know if latest self-hosted engine setup is stabilized, in other words can it be reliably used in production environment.

FYI, packages that we are using are RHEL 7.3 and RHV 4.1

Hi,

We are running 4.1.1.8-0.1.el7 on RHEL7.3 and do not face these issues. We are validating our REST-api tooling to handle both RHEV3 and RHV4 and our environment is stable. We did have some issues importing RHEV3.6 templates requiring a hot-fix. I suggest you open a support case for your stability issues.

regards, Siem

I have Installed a RHVH 4.1 Host. After that deployed a self hosted VM for manager using the shared storage using iscsi. I have access to the manager console for the first time. And I was able add another host into the system but could not able to add the same host into the manager. I have also added the storage domain into the data center.

I have rebooted the Host on which the self hosted VM was created. Aftre that I am unable to start that VM. Please suggest me if there is any shut down procedure for the VM and also the host?

Now How can I recover from this situation. Please suggest if anyone have the solution.

Hi Kaushik,

You should be able to start HostedEngine by running the following on a HE capable hypervisor:

  hosted-engine --vm-start

Do you see any error from this command? Are there any more errors in the logs? (/var/log/vdsm/vdsm.log)

Also check to make sure that you can see HostedEngine storage, and that ovirt-ha-agent is running:

  iscsiadm -m session
  multipath -l
  systemctl status ovirt-ha-agent
Close
