Andrei, I wouldn't recommend to downgrade, I did that in the past when we upgraded to 4.2.1 and I end up with even more issues. For the maintenance mode issue, can you verify that systemvm currently running (including VR) run as 4.4.2 ? I've saw behavior like this when upgrading to 4.4.x where CloudStack remain in Maintenance mode until all VR and system vm run to the proper ACS version. This is in /etc/cloudstack of VRs, cpvm and ssvm. if not at 4.4.2, try to install a new systemvm template and apply it to complete the upgrade of system VMs.
Hope this help and you won't have to deal with a rollback, if so, please share your experience On Wed, Feb 4, 2015 at 8:51 AM, Andrei Mikhailovsky <and...@arhont.com> wrote: > Daan, > > Do you mean that I should wait for the 4.5 branch to be out and try an > upgrade hoping that the issues are fixed? > > Why do you think downgrading the database is a tricky business?
