[ovirt-users] Gluster Data domain not correctly setup at boot

[Stefano Danzi]

I have one testing host (only one) with hosted engine and a gluster data 
domain (in the same machine).

When I start the host and the engine I can see data domain active "up 
and green" but in the event list I get:

- Invalid status on Data Center Default. Setting status to Non Responsive
- Storage Domain Data (Data Center Default) was deactivated by system 
because it's not visible by any of the hosts

If I try tu start a VM I get:

- Failed to run onDalesSRV on Host ovirt01
- VM onSalesSRV is down with error. Exit message: Cannot access storage file
'/rhev/data-center/00000002-0002-0002-0002-0000000001ef/f739b27a-35bf-49c7-a95b-a92ec5c10320/images......

The gluster volume is correctly mounted:

But link on '/rhev/data-center/0....' is missing:

If I put data domain on maintenace mode and reactivate it I can run the VMs.
Mounted fs are the same, but now I have links into /rhev/data-center/ :
