Hi,

After upgrading to 4.3.6, my storage domain can no longer be activated, rendering my data center useless.

My storage domain is local storage on a filesystem backed by VDO/LVM. It seems 4.3.6 has added support for 4k storage.
My VDO does not have the 'emulate512' flag set.

I've tried downgrading all packages on the host to the previous versions (with ioprocess 1.2), but this does not seem to make any difference. Should I also downgrade the engine to 4.3.5 to get this to work again. I expected the downgrade of the host to be sufficient.
What does engine log saying? Does it sending block_size =0 or 512?
If engine is sending 0 after you downgrade the hosts, then you need to downgrade engine too. 

As an alternative I guess I could enable the emulate512 flag on VDO but I can not find how to do this on an existing VDO volume. Is this possible?
I don't think you can change  emulate512 value once you create VDO volume.

Regards,
Rik

The oVirt Project is pleased to announce the general availability of oVirt 4.3.6 as of September 26th, 2019.

 

This update is the sixth in a series of stabilization updates to the 4.3 series.

 

This release is available now on x86_64 architecture for:

* Red Hat Enterprise Linux 7.7 or later (but < 8)

* CentOS Linux (or similar) 7.7 or later (but < 8)

 

This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for:

* Red Hat Enterprise Linux 7.7 or later (but < 8)

* CentOS Linux (or similar) 7.7 or later (but < 8)

* oVirt Node 4.3 (available for x86_64 only)

 

Due to Fedora 28 being now at end of life this release is missing experimental tech preview for x86_64 and s390x architectures for Fedora 28.

We are working on Fedora 29 and 30 support and we may re-introduce experimental support for Fedora in next release.

 

See the release notes [1] for installation / upgrade instructions and a list of new features and bugs fixed.

 

Notes:

- oVirt Appliance is already available

oVirt Node and Appliance have been updated including:

Given the amount of security fixes provided by this release, upgrade is recommended as soon as practical.
