Re: disk description
by Strahil
I don't get the idea.
Do you want to resize a vm disk that is encrypted inside the vm ?

Re: Cannot inquire Lease
by Strahil
It looks OK to me , but I'm no expert in that.
In such case you will have 5 GB as a reserve, which you can reduce, just to be able to delete some data (in this case VM).
The question that comes to my mind is - did you receive any warning by oVirt that gluster is almost full ?

Re: Cannot inquire Lease

Hm ... Removing it from the gluster but not inside oVirt can cause a lot of headaches.
Can you find that image in oVirt Storage -> Disks
Sadly , you got no other option and the optimal approach would be to take the deletion from oVirt UI/API before the storage gets full.
Ovirt has the option to notify you in advance.

RDO integration with oVirt
by Strahil
Hey guys,
I know that RHV has a nice integration with Red Hat's openstack , but I was wondering if RDO - oVirt are having that integration.
I've read a nice post : http://www.chrisj.cloud/?q=node/8
and I was wondering if I can do it - as I'm thinking about learning openstack.

VM IPsec network performance
by TranceWorldLogic .
Hi,
I have enable multi-queue feature on nic card and I am getting normal
throughput as 26 Gbps.
But when I am trying throughput test with IPsec I am getting only max
1.5Gbps. After looking at CPU usages, it is free more than 50%, I am not
getting why low throughput in ipsec case.
Below are my trial:
2nd, I tried to distribute multi-queue interrupt on mult-cpu but got same
result.
3rd, I tried nic passthrough and enable RSS, I got good throughput and CPU
usages.
Please help me to understand how to increase vnet performance for VM. And
also suggest me about ovirt setting.
I have also seen some presentation in google around virtio-crypto but as I
am using Guest and Host OS as centos 7.3, I can't use virtio-crypto device.
Thanks,

Re: Error virNetTLSContextLoadCertFromFile after upgrade from oVirt 4.2 to 4.3.4
by Strahil
What about setting the date and time manually somewhere at 2016 on all hosts and blockking ntp at all ?
Then the certs will be still valid and can be renewed ?
Just asking... Not sure what will be the outcome.

Re: [ANN] oVirt 4.3.5 Third Release Candidate is now available for testing
by Strahil
Hi Sandro,
Thanks for the info.
I've just updated my lab (gluster v6.1 -> 6.3 ) and the only issue I have detected so far is that the Advanced Options in UI show no info for the replica bricks, while the arbiter is working.
So the situation is the same as before the upgrade.

Re: Issues when Creating a Gluster Brick with Cache
by Strahil
The cache will not take immediately into effect. It is designed to save your cache disk and to load only repetitive data.
Try to run your benchmark 20 times and you will notice slight improvement over reading the same object.
Of course , you can use lvm cache in writethrough mode, but then it is recommended to use 2 cache disks (raid1 or lvm mirroring) .
