Updating nodes
by Gabi C 14 May '14

14 May '14

Hello! Which is the proper way of keeping nodes up to date? I tried from WebUI, after putting node on mainetnance " Host is in maintenance mode, you can Activate it by pressing the Activate button. If you wish to upgrade or reinstall it click here ." but no effect, so I guess that installing ovirt repo and fedora-ovirt-preview repo is the proper way, right?

Failure during self-hosted deployment: exception configuring management bridge

Hi, I'm trying to set up a fresh system on F19, using oVirt 3.4. When running hosted-engine --deploy, it fails during "Configuring the management bridge".

Those did not abort the deployment, however. What do those failures indicate? Thanks, Bob

Hitachi hus110 and ovirt

Hi all I wonder if anyone has a working setup with a HDS device. Right now I am seeing a weird performance issue. With default multipath settings dd of zeros into the /dev/mapper lun shows at 0.2kbps while writing directly into a single path at /dev/sdb provides 900Mbps. I am using 10g iscsi with 4 ports on the HDS and dual port cnas on the hosts Thanks Dan

Is it it me or does it take a very long time to delete a snapshot? Upwards of 30 minutes to delete a snapshot of a 7 GB drive
