Post Installation Health-Check

After the installation and configuration of TrilioVault for RHV did succeed the following steps can be done to verify that the TrilioVault installation is healthy.

Verify the TrilioVault Controller Cluster

The TrilioVault Controller Cluster can be verified from the base VMs themselves using the kubectl commands.

[root@master-node1 ~]# kubectl get pods
NAME                                           READY   STATUS    RESTARTS     AGE

[root@master-node1 ~]# kubectl get pods -n trilio

Verify API connectivity from the RHV-Manager

The RHV-Manager is doing all API calls towards the TrilioVault Appliance. Therefore it is helpful to do a quick API connectivity check using curl.

The following curl command lists the available workload-types and verfifies that the connection is available and working:

curl -k -XGET https://30.30.1.11:8780/v1/admin/workload_types/detail -H "Content-Type: application/json" -H "X-OvirtAuth-User: admin@internal" -H "X-OvirtAuth-Password: password"
######

Verify the ovirt-imageio services are up and running

TrilioVault is extending the already exiting ovirt-imageio services. The installation of these extensions does check if the ovirt-services come up. Still it is a good call to verify again afterwards:

RHV 4.3.X

On the RHV-Manager check the ovirt-imageio-proxy service:

systemctl status ovirt-imageio-proxy
######
● ovirt-imageio-proxy.service - oVirt ImageIO Proxy
   Loaded: loaded (/usr/lib/systemd/system/ovirt-imageio-proxy.service; enabled; vendor preset: disabled)

 Main PID: 1834 (python)
   CGroup: /system.slice/ovirt-imageio-proxy.service
           └─1834 bin/python proxy/ovirt-imageio-proxy

On the RHV-Host check the ovirt-imageio-daemon service:

systemctl status ovirt-imageio-daemon
######
● ovirt-imageio-daemon.service - oVirt ImageIO Daemon
   Loaded: loaded (/usr/lib/systemd/system/ovirt-imageio-daemon.service; enabled; vendor preset: disabled)

           └─1442 /opt/ovirt-imageio/bin/python daemon/ovirt-imageio-daemon

RHV 4.4.X

On the RHV-Manager check the ovirt-imageio-proxy service:

systemctl status ovirt-imageio
######
● ovirt-imageio.service - oVirt ImageIO Daemon
   Loaded: loaded (/usr/lib/systemd/system/ovirt-imageio.service; enabled; vend>

   CGroup: /system.slice/ovirt-imageio.service
           └─1041 /usr/libexec/platform-python -s /usr/bin/ovirt-imageio

On the RHV-Host check the ovirt-imageio-daemon service:

systemctl status ovirt-imageio
######
● ovirt-imageio.service - oVirt ImageIO Daemon
   Loaded: loaded (/usr/lib/systemd/system/ovirt-imageio.service; enabled; vend>

Verify the NFS Volume is correctly mounted

TrilioVault mounts the NFS Backup Target to the TrilioVault Appliance and RHV-Hosts.

To verify those are correctly mounted it is recommended to do the following checks.

First df -h looking for /var/triliovault-mounts/<hash-value>

df -h

Secondly do a read / write / delete test as the user vdsm:kvm (uid = 36 / gid = 36) from the TrilioVault Appliance and the RHV-Host.
