Hi @halvor, FYI, ACL V2 / RBAC is now available in the REST API. You can create a privilege that only give you read privilege on your host. You can see the RBAC doc. A dedicated thread is available on the forum thread, please feel free to share your feedback. Thank you.

@Andrew said in XOA suddenly "empty" during rolling update: @halvor Yes, kind of... The pool master must be updated and rebooted first. If you move the master to a different host then you are no longer rebooting the pool master first. XOA is just a very smart client and needs the pool master to provide all of the pool information. Secondary machines will just redirect to the master, so if you try to connect XOA to one as a backup it won't work. You just need to wait for the master to reboot and return to a functioning state and wait for XOA to automatically reconnect. The everything will start happening again. If your master host is destroyed (ie. software corruption, hardware failure) then an existing host can be forced to take over the pool as master, but this is not a good thing to do unless the actual pool master is unrecoverable. Ok, great, thank you for clearing this up!
