Good Day To all;

oVirt 4.3.4.3-1.el7

6 Dell R710 oVirt Nodes

10 gig Infiniband iSCSI

Standalone Engine

After an error during scheduled automated VM backkup, the iSCSi datastore that the VMs beinng backed up lived on suddenly went inactive and refuse to activate.

The backup job did not finish as the source datastore went inactive but the task did clear from the console after i restarted the ovirt-engine service.

I have tried:

1. Restart the ovirt-engine service

2. Restarted the engine physical server.

3. Tried to migrate the VM disks to a different datastore (failure)

The virtual machines that are currently living on the inactive datastore are still running and accessible.

Trying to reboot one of those VM as a test fails as the VM will not come up due to the system believing that the datastore is inactive.
