@k0nsl Welcome to the Rockstor community and thanks for the report.
So I’m assuming that all you did was press the “Update” button in the top right then?
The “POST” part here indicates that the error was during an update of the database, when on occasions the server side has run out of connections we get a timeout message so I don’t think this is that. And we have made some changes in the more modern code to remove the number of redundant checks that we were making on the server side so that should happen less in the future.
This is quite curios. Does your rockstor_rockstor pool look to be rw still or has it gone read only as this would cause this same issue potentially as the post (db write) would be unable to complete. Or you system drive could be low on space, but again that would have other knock-on.
There is a pending issue related to an upstream update to python-tornado that could be breaking our background task manager that does some of the Rock-ons stuff. There may be some clues in the following file:
