Clear task after export to ova unfinisced
by radchenko.anatoliy＠gmail.com
Hi all,
after succesfully done ova export of 120gb VM i launched export ova of 250gb vm but it is not finished. The time of task must be about 20 minuts. Now i have one unfinished task and locked vm.
I know that it is complex task indluding a series of steps and clean db of task manually is not resolved it.
Some info:
Gluster replica 3 hiperconverged configuration
[root@cluster23 ~]# vdsm-client Host getAllTasksInfo
{}
tail -f engine.log

Some of my systems have megaraid sas2 raid controllers, which Red Hat have stopped supporting "under EL8", and all the variants have followed suit.

If the hardware is old, and won't support EL8, the best option is to update to oVirt 4.3.10 and update CentOS to 7u9.
Some of my systems have megaraid sas2 raid controllers, which Red Hat have stopped supporting, and all the variant have followed suit.
I have tried the Elrepo DUD's to work around the problem, but my results (in the 4.4.1/4.4.2 timeframe) were not satisfactory.

Hi,
I have 2 oVirt nodes still running on CentOS 7.6.
rpm -qa | grep ovirt - results in version 4.2.
Does it makes sense to upgrade CentOS 7.6 to Stream, and then upgrade oVirt Node sw, or just leave for a couple of years till hardware will be trashed?
I’m always keep oVirt Engine up to date, so my only concern if at any point it will stop support old Node sw.
Thanks in advance for any suggestion.
Andrei

Cloud-Init - What am I doing wrong?
by jeremy_tourville＠hotmail.com
I am running into an issue using Cloud-Init on CentOS 7. I have imported OpenStack Glance Generic cloud images for CentOS 7 & 8 and I chose to save them as a template at the time of import.
In the template, under Initial Config I defined the following values:
-cloud-init : checked
-configure time zone: checked
-choose dropdown for the correct timezone
-VM Hostname, Authentication & Networks are all blank
-Custom script:
#cloud-config
users:
- name: ansuser
passwd: $6$TcX2D/LcPtq/a$m6AKlcIbZXL9ZJGNSgeXjnKGsz98Yw.v7rt5m18zunittqjMTygf7KLliwxXwzFrvj8rrFpOMGZmUYoX.mWib.
In theory I think this should create my user and set the password for my user. When I go to login to the system the login for my new user fails. What am I doing wrong?
If I leave the Custom Script blank and put the user in the Authentication section the login works as expected. This tells me the image itself is working properly and is accepting Cloud-Init input. It would be my preference to add the user under the Custom Script section so I can further extend some functionality such as sudo: ALL=(ALL) NOPASSWD:ALL and SSH keys so that an initial Ansible config could be run easily.
I am going to test 8 in the same manner and see what happens. I sort of expect the same results though. Thanks in advance for you input!

upgrading gluster brick os from CentOS7 to 8
by Jiří Sléžka
Hello,
I'm in progress of moving my oVirt HCI cluster to production. It was a
bit complicated process because I had two new servers to install oVirt
from scratch in the lab and three old servers with standalone kvm
hypervisors in production. One of them (installed with CentOS7) was good
enough to join HCI cluster. All three old kvm servers had production vms
running on them.
New cluster was installed with CentOS8 and oVirt4.4, I started with
single node, then expanded it to two hosts with one another which acts
as arbiter (just for stability in lab envirnment).
After some testing and tuning I moved this two node cluster (without
arbiter node) to my server housing. Then I prepared gluster brick on
that one old server which I want reuse and join it to gluster storage so
now it is replica 3 - two nodes are CentOS8 based and acts as oVirt
hosts, one is CentOS7 and acts also as standalone kvm hypervisor.
Then I migrated all vms from standalone kvm hypervisors to oVirt, then
switched off two oldest hosts.
Now I would like to reinstall CentOS7 node to oVirt host. My plan is to
keep gluster brick fs and backup configuration and restore it after
reinstall to CentOS8 as mentioned in
https://mjanja.ch/2018/08/migrate-glusterfs-to-a-new-operating-system/.
I want to speed up gluster healing. Does it make sense?
Now the questin: Brick fs was created on CentOS7 and don't have new xfs
features FINOBT,SPARSE_INODES,REFLINK. Could it be problem? Will be
better to recreate fs in CentOS8 and then do full heal? I am afraid that
it will take a long time and make big load to production hosts.
TL;DR: Does gluster/oVirt4.4 make use of FINOBT,SPARSE_INODES,REFLINK
xfs features?
btw. oVirt is great product and HCI looks really functional and usable
(with 10GE network and SSDsof course). Big thanks to developers and
community!
Cheers,
Jiri

posix data domain is just NFS data domain under the hood, with
modified mount options, so it share the same limits of NFS data
domain.
I'm not sure how do you get the compatibility issue - do you mean provisioning
engine on a host with 4d disk (using libvirt and local storage) and then copying
to data domain created on same local storage (512 bytes sector size)?
> How to be in this case?
I think this should work as is since the bootstrap vm created using libvirt
is using 512 bytes sector size, regardless of the underlying storage sector
size (qemu hides the actual sector size from the vm). So the vm starts
with 512 bytes sector size, and them move to another storage which again
have 512 bytes sector size.
This also works when the other storage uses 4k sector (e.g hyperconverge
using gluster and vdo) size since again qemu hides the underlying storage
sector size.

blok size and 512e and 4k
by radchenko.anatoliy＠gmail.com
Good day,
Some controllers do not allow to set a 4k block on a boot device.
With some installations of Ovirt in the configuration of ssd for boot OS and hdd (4k) for data domain, engine is installed on ssd with a block size of 512e and then transferred to hdd 4k. and if I wanted to leave the engine on ssd (in a separate partition which will also have a size of 512e), I encountered an incompatibility error between block sizes 512 and 4k (example glusterfs or when the data domain was configured as posix compliant fs). NFS domain passed.
As I understand it, the NFS uses 512e as well as the drivers of the guest machines, and a VM created on a domain with a 4k block will still have 512e. As a result, we have a block of size 512 in any case.
Does it make sense to use devices with a 4k block at the present time? Is there any configuration to take advantage of 4K?
Thanks in advance.
Best regards.

Hosted Engine Deployment
by Harry O
Why does the HE Deployment Not deploy a hosted engine dc and cluster which fits the host in version?
My Hosted Engine Deployment now fails again because of "Host hej1.5ervers.lan is compatible with versions (4.2,4.3,4.4,4.5) and cannot join Cluster Default which is set to version 4.6."
I think the deployment shoud make a dc and cluster that fits the host that is used to deploy. Otherwise it's doomed to fail.
Is there a proccess for fixing this? I can't change the version from HE ui as I'm instructed to, there is no other options on datacenter other then 4.6:
[ INFO ] You can now connect to https://hej1.5ervers.lan:6900/ovirt-engine/ and check the status of this host and eventually remediate it, please continue only when the host is listed as 'up'
[ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : include_tasks]
[ INFO ] ok: [localhost]
[ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Create temporary lock file]

ovrt node kernel
by Giulio Casella
Hello everybody,
using ovirt node many of the drivers to access storage are not in the
kernel drivers (anymore).
For example I have a bunch of (old) hypervisors (50+), with infiniband
nics, used to access storage. For all those hypervisors I abandoned
ovirt node, in favor of a base CentOS stream distro, with ovirt repo and
using kernel-plus repo (conatining all the needed stuff).
Obviously this is not a step I liked, I definitely prefer ovirt node.
Now my proposal: why don't include kernel-plus in ovirt-node, instead of
traditional kernel?
I know this would be a big change, and maybe @Sandro and all RH guys
(they have a more general perspective) can see some drawback I don't,
but... hey, I just tried! :-)
Thank you in advance,
Giulio
