I wasn't able to reproduce it here.
So there is no suspected patch from oVirt side that might have caused it.It's the firewall. I've fixed it[1] and specifically[2] but probably not completely.Great! Wasn't aware your patch address that, I've replied on the patch itself, but I think we need to split the fix to 2 seperate patches.Perhaps we should try to take[2] separately.Y.[2] https://gerrit.ovirt.org/#/c/81766/3/common/deploy-scrip ts/setup_storage_unified_he_ex tra_el7.sh It is probably also the reason why HC suites are failing, since they are using also HE for deployments.I think this issue should BLOCK the Alpha release tomorrow, or at the minimum, we need to verify its an OST issue and not a real regression.Links to relevant failures:Error snippet:03:01:3803:01:38 --== STORAGE CONFIGURATION ==--03:01:3803:02:47 [ ERROR ] Error while mounting specified storage path: mount.nfs: No route to host03:02:58 [WARNING] Cannot unmount /tmp/tmp2gkFwJ03:02:58 [ ERROR ] Failed to execute stage 'Environment customization': mount.nfs: No route to host
