Changing name and/or IP of gluster bricks
by michael＠wanderingmad.com 28 Dec '18

28 Dec '18

I have an infiniband connection betweeen all three ovirt hosts. I have one gluster drive that goes over the infiniband, but the other one is running over the gigabit link. Is there an easy way to either change the host name of the bricks or change the IP to force the traffic over the infiniband?

Ovirt hosts running 4.2.3-1.el7 fail to upgrade to CentOS 7.6
by Andrea Dell'Amico 27 Dec '18

27 Dec '18

Hello all, I tested an upgrade of one of my hypervisors. The ‘yum update’ fails because of a dependency: —————————— ---> Package nbdkit-plugin-vddk.x86_64 0:1.2.6-1.el7_6.2 will be installed --> Processing Dependency: nbdkit(x86-64) = 1.2.6-1.el7_6.2 for package: nbdkit-plugin-vddk-1.2.6-1.el7_6.2.x86_64 --> Finished Dependency Resolution Error: Package: nbdkit-plugin-vddk-1.2.6-1.el7_6.2.x86_64 (updates) Requires: nbdkit(x86-64) = 1.2.6-1.el7_6.2 Available: nbdkit-1.2.6-1.el7.x86_64 (base) nbdkit(x86-64) = 1.2.6-1.el7 Available: nbdkit-1.2.6-1.el7_6.2.x86_64 (updates) nbdkit(x86-64) = 1.2.6-1.el7_6.2 Installing: nbdkit-1.2.7-2.el7.x86_64 (ovirt-4.2-epel) nbdkit(x86-64) = 1.2.7-2.el7 —————————— It seems that the ovirt-epel repository has a nbdkit* version older than the CentOS updates one. Is it a known problem? Best, Andrea -- Andrea Dell'Amico http://adellam.sevenseas.org/

------=_Part_20329569_1409874801.1519819859027 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, I'm testing backup & restore on Ovirt 4.2. I follow this doc https://www.ovirt.org/documentation/admin-guide/chap-Backups_and_Migration/ Try to restore to a fresh installation but always get this error message: restore-permissions Preparing to restore: - Unpacking file 'back_file' Restoring: - Files Provisioning PostgreSQL users/databases: - user 'engine', database 'engine' Restoring: FATAL: Can't connect to database 'ovirt_engine_history'.

oVirt: access external Provider through Proxy
by Tian Xu 26 Dec '18

26 Dec '18

Hi expert, 'ovirt-image-repository' storage domain created by default in my ovirt 4.2 environment , but unfortunate my ovirt-engine and ovirt-node machines sits in a private network where it can only access external services through a HTTP proxy. Is there a way to tell ovirt-engine the HTTP-Proxy to use ? Thanks, Xu

Hello Fellow users, Platform : Ovirt Engine 4.1 Problem : ISO Domain server has crashed. It is a separate NFS server. I am unable to replace the ISO Domain. I have the old one in maintenance but it won't detach. It says. VDSM command DetachStorageDomainVDS failed: Storage domain does not exist: (u'0ad098e9-65e7-494a-90f7-e42949da3f85',) Which is quite true it does not exist.. Any suggestions? Thank you
