Description Javier Coscia 2018-06-15 12:54:03 UTC

Description of problem:

Engine won't start if entire /var/cache/ovirt-engine dir is missing/deleted. 

It will also would fail to upgrade / add a host into it with a misleading message "Failed to enroll certificate for host" instead of "cannot create tarball"


Version-Release number of selected component (if applicable):

rhevm-4.1.10.3-0.1.el7.noarch
ovirt-engine-4.1.10.3-0.1.el7.noarch


How reproducible:

100%

Steps to Reproduce:
1. Move or remove /var/cache/ovirt-engine dir on engine system
2. Start ovirt-engine service

Another repro:

1. Start ovirt-engine service
2. Move or remove /var/cache/ovirt-engine dir on engine system
3. Try to upgrade or add a new host into the cluster

Actual results:

Engine cannot start or cannot add/upgrade host in cluster



Expected results:

Engine should be able to re-create this /var/cache/ovirt-engine dir while starting and while adding/upgrading host in clusters and print a clear message to the user

Comment 4 Moti Asayag 2018-06-26 16:24:09 UTC

In case of a missing /var/cache/ovirt-engine folder, the host-deploy will fail with the following error in engine.log:
