OK.

Re: [ovirt-users] Master Doamin - Ovirt 3.6 - hoted engine
Thanks Simone, I'll wait for official 3.6.3 release. That's cool that it has been fix patch released. I'll appreciate for workaround procedure and I think that other users too. Do you have that procedure? I've tried do this by myself, but finally I've redeployed whole environment. I've changed records in the postgres database. (table storage_domain_static) It is not enough. I've try to change metadata files on the storage but after that storage domains has been red :-(.

Re: [ovirt-users] Master Doamin - Ovirt 3.6 - hoted engine
Interesting. You are right but :-) Scenario: 1. Empty DC and Cluster. 2. Creation of the storage domain type data based on gluster. This domain storage as first becomes a master storage domain. 3. After previous step, ovirt manager imports domain storage where resides hosted engine. Thats all. After reboot of the hypervisor (vm hosted engine power off state before) situation has changed because as I've wrote earlier appeared a problem with access to gluster service. Right now I don't know how to becomes my original master storage domain as previously. Even If I've made new data storage domain master DS not floating from hosted_storage. Master SD will stay on the hosted_storage for ever :-( Am I right? Maybe not, but I don't know the different procedure then create new domain and master SD amend to maintenance mode. 2016-02-23 17:13 GMT+01:00 Simone Tiraboschi <stira...@redhat.com>: > > > On Tue, Feb 23, 2016 at 4:19 PM, Dariusz Kryszak < > dariusz.krys...@gmail.com> wrote: > >> Hi folks, >> I have a question about master domain when I'm using hosted engine >> deployment. >> At the beginning I've made deployment on NUC (small home installation) >> with hosted engine on the nfs share from NUC host.

[ovirt-users] Ovir (rhev) backup authomation
Hi all, I would like to share with all my couple scripts which I've made for the backup automation process. If your backup system not support virtual environment like ovirt or rhev, you can use it as workaround :-) It is not a classical backup solution (especially differential backup, compression, deduplication ). This is protection against loss your vm and the data. All what you need it is to change credential and information regards environment like url. Everything I've described in the code. For new environment (3.5> with rhe or centos 7) you can change or comments lines like power off during cleanup snapshots. Please enjoy. jezyk backup_scripts (1).tar.gz Description: GNU Zip compressed data ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
