"Deactivating Storage Domain" error
by Juan Pablo 26 Dec '16

26 Dec '16

Hi, first of all , thanks to all the Ovirt/Rhev team for the outstanding work! we are having a small issue with Ovirt 4.0.5 after testing a full end of year infrastructure shutdown, everything came back correctly except that we get a 'Deactivating Storage Domain' under the tasks tab. another dc/cluster running 3.6.7 reported no error with same maintenance procedure.. maybe we did something wrong? would you please be so kind to point me on the right direction to fix it? I looked vdsClient -s 0 getAllTasks , but returns nothing... thanks for your time guys and merry christmas and happy new year if we dont talk again soon! JP

ovirt.org is back online
by Eyal Edri 25 Dec '16

The site is back online thanks for Duck in helping clearing the log files which caused the gear to get stuck. I understood that the site is planned to move to another location, with more storage so hopefully these kind of outage will be rare soon after. -- Eyal Edri Associate Manager RHV DevOps EMEA ENG Virtualization R&D Red Hat Israel phone: +972-9-7692018 irc: eedri (on #tlv #rhev-dev #rhev-integ)

------FJPTAOTC7WINF1RXJ2RM2050Z3DNHO Content-Transfer-Encoding: 8bit Content-Type: text/plain; charset=UTF-8 Hi all, I am thinking to setup an environment with oVirt and centralized storage using a NAS that supports NFS and iSCSI. The setup will be used to host approx 20 VMs. The VMs will be running critical services and not for testing. I have seen several from QNAP, iXsystems (freenas mini), ... What NAS would you recommend for this setup? Thanx, Alex -- Sent from my Android device with K-9 Mail.

Why difference between upgrade paths 3.6 to 4.0.x between RHEV and oVirt?
by Gianluca Cecchi 23 Dec '16

23 Dec '16

Hello, in June 2016 oVirt 4.0.0 GA was released and I in-place upgraded from an existing 3.6.5 to it. In 4.0.0 release notes it was described as the method to use. I see that it still remains the same for 4.0.5: http://www.ovirt.org/release/4.0.5/ and also for upcoming 4.0.6 (RC5 at least) there is not yet anything special: http://www.ovirt.org/release/4.0.6/ Instead, if I go and read the RHEV 4.0 documentation I notice: https://access.redhat.com/documentation/en/red-hat-virtualization/4.0/paged… " Red Hat Virtualization Manager 4.0 is only supported on Red Hat Enterprise Linux 7. A clean installation of Red Hat Enterprise Linux 7 and Red Hat Virtualization Manager 4.0 is required, even if you are using the same physical machine used to run Red Hat Enterprise Virtualization Manager 3.6. The upgrade process involves restoring Red Hat Enterprise Virtualization Manager 3.6 backup files onto the Red Hat Virtualization Manager 4.0 machine. " Is there any particular technical reason for this substantial difference? Clearly they are not the same sw but it seems strange to me this discrepancy. Suppose I have a mix of oVirt and RHEV environments it could be simpler to have a common path, where possible. For example, can I also use the documented RHEV approach for oVirt? At what extent? Thanks Gianluca

Windows Product Activation
by Nicolas Ecarnot 23 Dec '16

23 Dec '16

Hello, Most of our virtual machines are Linux, but an increasing number of windows VMs are being integrated into our oVirt DCs. We bought tons of windows server licences, and successfully activated them. Due to how Windows Product Activation is working, when a windows VM is migrating from a host to another, this product activation is reset, launching a 30 days countdown to auto-shutdown. According to this old page : https://mazimi.wordpress.com/2007/07/11/getting-around-windows-activation-w… and what I can read in microsoft's 2012 server documentations, I then can re-activate it twice during the next 90 days. Assuming I *want* to have *no* control upon the location of the VMs amongst their hosts (I want them to fly freely, confident in the lovely auto-balance scheduler), I understand all this is not the way to go. At present, we have 2003, 2008 and 2012 server editions. the only things I can read about windows 2012 server is related to the commercial aspects (standard licence = 2 VMs, datacenter licencce = infinite # of VMs), but not about this Windows Product Activation trouble. How do you deal with this? Is there a special licence type or something dedicated that would prevent such an uncomfortable situation? (Christmas is near, I favor soft terms.) Regards. -- Nicolas ECARNOT

Regarding DAS for Shared Storage
by rex 22 Dec '16

22 Dec '16

Hi, Have a VRTX Chassis enclosure populated with two Dell PowerEdge M620 Blades and has a built-in DAS storage. Created a 1 TB Virtual Disk from the DAS storage using the Dell iDRAC interface. This block device is accessible from the two blades (CentOS 7 OS) like shown below, [root@node1 ~]# lsblk /dev/sdc NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdc 8:32 0 1024G 0 disk [root@node2 ~]# lsblk /dev/sdc NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdc 8:32 0 1024G 0 disk oVirt rpms has been installed on both the blades with the aim of configuring them as oVirt nodes with Live Migration feature. But other than the DAS we don't have any storage which can be used as shared storage. So can some one please tell me whether the above block disk can be used as a shared storage (i.e mounted on the two nodes at the same time) and if it is possible how can this be done. Thank you.
