Controller recomandation - LSI2008/9265
by Leo David
Hi Everyone,
For a hyperconverged setup started with 3 nodes and going up in time up to
12 nodes, I have to choose between LSI2008 ( jbod ) and LSI9265 (raid).
Perc h710 ( raid ) might be an option too, but on a different chassis.
There will not be many disk installed on each node, so the replication will
be replica 3 replicated-distribute volumes across the nodes as:
node1/disk1 node2/disk1 node3/disk1
node1/disk2 node2/disk2 node3/disk2
and so on...
As i will add nodes to the cluster , I intend expand the volumes using the
same rule.
What would it be a better way, to used jbod cards ( no cache ) or raid
card and create raid0 arrays ( one for each disk ) and therefore have a bit
of raid cache ( 512Mb ) ?
Is raid caching a benefit to have it underneath ovirt/gluster as long as I
go for "Jbod" installation anyway ?
Thank you very much !

status of uploaded images complete and not OK
by Gianluca Cecchi
Hello,
I'm using oVirt 4.3.2 and I have an iSCSI based storage domain.
I see that if I upload an iso image or a qcow2 file, at the end it remains
in "Complete" status and not "OK"
See here:
https://drive.google.com/file/d/1rTuVB1_MGxudVCx-ok7mE2BirWF0rx7x/view?us...
I can use them, but it seems a bit strange and in fact I had a problem in
putting a host into maintenance due to this. See here:
https://lists.ovirt.org/archives/list/users@ovirt.org/message/4UJ75YMYSPW...
In fact from db point of view I can see this (for other 2 more uploads done
in March as described above), where status remains in phase 9....

Any hint? anyone to verify an upload on block storage on 4.3.2?

Eve-ng KVM acceleration not working in Ovirt
by robertodg＠prismatelecomtesting.com
Hello everyone!
Actually I'm encountering a huge problem that I'll explain in steps, in order to be clear and discursive. First of all, I've deployed eve-ng Community Edition 2.0.3-92 on a KVM with those specs:
Server DELL PowerEdge R420
CPU: Intel(R) Xeon(R) CPU E5-2420 0 @ 1.90GHz (24 Core total)
RAM: 24GB RAM
HDD: 4x 2TB
All was working fine, KVM virtualization was working well and i was able to deploy qemu images like PaloAlto (PANOS-8.0.5) with qemu-options accell=kvm without any problem.
After an internal company upgrade, i've decided to migrate this tool on Ovirt 4.2, in a node with following specs:
SuperMicro Server
CPU: Intel (R) Xeon (R) Platinum 8160T @ 2.10GHz (96 Core Total)
RAM: 256 GB (16x16) DDR4 2666Mhz Samsung M393A2K40BB2-CTD
HDD: x 2 Seagate ST500LM021-1KJ152 SATA 3.0 500GB
SSD: x 2 SSD Samsung SSD 850 PRO 1TB
NVMe: x 4 KXG50ZNV512G TOSHIBA 512GB (RAID0)
Before migration eve-ng had 12 cores, 12 GB RAM and 90 GB HDD. After migration he has now 16 Core, 32GB RAM and RAID0 100GB.
On Ovirt Pass-Through Host CPU is activated on VM, CPU nesting is activated too and after new release (2.0.5-95) those are eve-info command logs:
eve-ng-info-ovirt: https://paste.fedoraproject.org/paste/Mom-~CXmnlU3cWCUdxPXFg
Those are the previous eve-info command logs (on KVM):
eve-ng-info-kvm: https://paste.fedoraproject.org/paste/AhqiapiyG5lJcHQBlrbJgw
Also, here you can find output of cpuinfo of both node (KVM and Ovirt):
cpuinfo-kvm: https://paste.fedoraproject.org/paste/6TQDHxCmiEMosF1qtcdSDQ
cpuinfo-ovirt: https://paste.fedoraproject.org/paste/LmieowOvc7WwkEWW9JMduQ
On both nodes, output of cat /sys/module/kvm_intel/parameters/nested is Y
at least, this is the output of virsh dumpxml of both nodes:
eve-ng-ovirt.xml: https://paste.fedoraproject.org/paste/s5SbdWhBHTWJs9O2Be~y8w
eve-ng-kvm.xml: https://paste.fedoraproject.org/paste/Yz1E9taAkNT-JyTj8cBR-g
However, after migration, i'm not able to deploy qemu images with accell=kvm enabled anymore. With same example PANOS-8.0.5 i'm able to run this qemu image only with this setting removed.
Thinking on a migration problem, i've deployed a new eve-ng VM with same specs but problem is still present.
Have you any idea on what might be the problem?
Thanks for your support.

used network for uploading api
by Nathanaël Blanchet
Hi all,
I noticed a bad transfer when uploading a floating disk through the
upload API.
I set up two networks, one for management with a dedicated 1Gb link and
an other 10Gi for other vlans.
It seems that the upload is done by the management network, can anyone
confirm it?

Re: [Gluster-users] Gluster 5.5 slower than 3.12.15
by Strahil
Hi Amar,
I would like to test Cluster v6 , but as I'm quite new to oVirt - I'm not sure if oVirt <-> Gluster will communicate properly
Did anyone test rollback from v6 to v5.5 ? If rollback is possible - I would be happy to give it a try.
Best Regards,
