Couple questions about a fixed ‘bug' in the release notes for this:

Does https://bugzilla.redhat.com/show_bug.cgi?id=1517237 mean that ovirt will no longer use libgfapi for any VMs, or is it just removing the check box from the storage GUI?

This removes the option to enable gfapi at an individual cluster level from the UI. Since the libgfapi access does not allow for HA when the gluster server used to provide path info to storage server is down, and does not support live storage migration - we wanted to make sure that users do not enable this feature inadvertantly.


If it is removing the capacity, I have several questions:
- what happens to my cluster which has it enabled from CLI?

If you have set this as a config option for 4.1 from CLI, it will continue to work.

- what happens to my currently running VMs using it?
- why are you removing a major feature with a bug notice and no further information?

See above.

- it doesn’t seem to affect my HA vms, I’ve seen my 4.1.8 system properly restart systems using it (node/libvirtd crash that seems to have been related to spectre/meltdown firmwares)

HA is an issue only when the gluster server used to provide volume information is down. For instance, if you have provided the "serverA:/volumeA" in your storage domain path , and if the other servers in replica are up but serverA is down, VM cannot restart. Have you tested this?

- or does this only affect the hosted-engine VM?

Again, see above.


If it doesn’t actually remove the capability, this is ignorable. But this is a much wanted feature for me, and I’ve been quite happy to finally get to use it. Not going to be pleased if it disappears without notice.

Can you share any performance improvement numbers that you have seen after turning on libgfapi access, also information about your workload would be helpful.

thanks!
