Re: huge page in ovirt 4.2.7
by Sharon Gratch 08 Apr '19

08 Apr '19

Hi Fabrice, The "hugepages" custom property value in oVirt should be set to *size of the pages in KiB* (i.e. 1GiB = 1048576, 2MiB = 2048). In addition, it is recommended to set the huge page size of the VM to the largest size supported by the host. In the configuration you sent, the huge page size of the VM is set to 64 KiB and since the VM's allocated memory size is at least 32,768 MiB then it requires at least (32768 * 1024/64=) 524,288 pages. Since you only have 120 pages declared in the host then it failed with an error "...there are not enough free huge pages to run the VM". So to solve the problem, please change the VM's huge page size to be the same as the host's huge page supported size which is 1GiB and therefore hugepages value should be 1048576 KiB instead of 64: <custom_property> <name>hugepages</name> <value>*1048576*</value> </custom_property> Please note that since total VM's memory size is no more than 64 GB then only 64 pages will be needed by the VM and it's < 120 pages supported by the host and therefore OK. Hope it helped.

Re: ERROR running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode

So if the engine is down, it's not going to update the DB and so it will never update the global maintenance status field.

4.3 rc2: info about shutdown of last host and networking page
by Gianluca Cecchi 07 Apr '19

07 Apr '19

Hello, env with single host HCI deployment from node ng iso After powering off VMs, put into global maintenance, shutdown hosted engine, I then run shutdown on host. This I think would simulate also a total shutdown scenario when you have the final step of shutdown of the final host. This is what I see in console about failure in several unmounts, both /var and /var/log and also gluster related filesystems Could there be any dependency problem? See here the screenshot: https://drive.google.com/file/d/1wqqXlmT66hHLJ8DMcwfPvDXJHkWm_ijE/view?usp=… Also I have not understood the networking page of host in Cockpit: https://drive.google.com/file/d/1isX4F8qPcFmTyhmCVnZadhp6NY0R9Sy7/view?usp=… in my scenario I was downloading a 1Gb image for the CentOS Atomic host from public glance repo. Questions: - how to explain the receiving box graph? What are the different color lines for? - In "receiving" column inside the "interfaces" sections I see all "0" for gluster one (eth1) and empty (no value) for ovirtmgmt (perhaps because it is unmanaged from host point of view?) Also, it seems to me that the temporary bridge for hosted engine deployment on 192.168.124.0 (virbr0) is still there even after finishing the deployment, even if with "no carrier"... is this expected? Better perhaps to undefine the network after deployment? Gianluca

Agentless Backup update: Trilio Vault...what a joke, pay $7500
by femi adegoke 07 Apr '19

07 Apr '19

Back in June of 2018, I posted regarding Agentless backup solutions. Greg Sheremeta replied & mentioned Trilio. The rest of the story...well just read on... These guys at Trilio have turned out to be a complete waste of time. (I could use some more colorful language) After my post & reply from Greg Sheremeta, I followed up with Trilio. A lot of promises/dates were made (by Trilio) as to when a beta would be made available for testing. Needless to say, they never came through. Finally in Dec 2018, they said we are ready for the demo, we will show you a working product. The day came, Trilio said, sorry it's too close to Xmas, we will postpone the demo's till 2019. In 2019, I continued to follow up & finally they set a date for another demo - Jan 29. On Jan. 29, we get on the Webex, they said, sorry the demo just broke 10 mins prior to our call, so no demo. They show me some screenshots & their OpenStack version & again promise to get me beta software in a few days. I continue to follow up (via email) Yesterday (Feb 6), I get an email from Thomas Lahive GM; Sales and Alliance Partners....(copied & pasted below): "We started RHV betas and decided to prioritize current Trilio customers (those that purchased Triliovault for Openstack). If you would like to be part of the beta now then We can sign you up as a certified Trilio reseller which has a $7,500 Starter Fee. The $7,500 will be credited against your first customer order that is at least $7,500 so it will eventually cost you nothing. Many of our partners can apply the fee against revenue so it's a great tax incentive, but you can confirm with your finance department. Please Lmk how you would like to proceed." Please remember, I have never seen a working demo of this product, never. Is this typical behavior of RH partners?

VM bandwidth limitations
by John Florian 05 Apr '19

05 Apr '19

In my oVirt deployment at home, I'm trying to minimize the amount of physical HW and its 24/7 power draw. As such I have the NFS server for my domain virtualized. This is not used for oVirt's SD, but rather the NFS server's back-end storage comes from oVirt's SD. To maximize the performance of my NFS server, do I still need to use bonded NICs to increase bandwidth like I would a physical server or does the VirtIO-SCSI stuff magically make this unnecessary? In my head I can argue it both ways, but have never seen it stated one way or the other, oddly. -- John Florian

Hosted-Engine constantly dies
by Strahil Nikolov 05 Apr '19

05 Apr '19

Hi Guys, As I'm still quite new in oVirt - I have some problems finding the problem on this one.My Hosted Engine (4.3.2) is constantly dieing (even when the Global Maintenance is enabled).My interpretation of the logs indicates some lease problem , but I don't get the whole picture ,yet. I'm attaching the output of 'journalctl -f | grep -Ev "Started Session|session opened|session closed"' after I have tried to power on the hosted engine (hosted-engine --vm-start). The nodes are fully updated and I don't see anything in the gluster v5.5 logs, but I can double check. Any hints are appreciated and thanks in advance. Best Regards,Strahil Nikolov
