Did anyone notice the web ui hanging quite a bit and not updating whatever process you had done previously without killing that tab and re-login?
Hmm which operating system?
Freenas 10
clicked in the webUI for 10 beta to check for updates then install-- was taking way to long to get the webUI back up, consoled in and it was stuck in a boot loop. Deleted the VM and did a fresh install, then imported the data sets so back up and running.
When you ran 10 and then bumped back to 9, did you have any issues with your pool(s)?
no
