@Thad.
It looks to me that you’re currently mounted in read-only mode, which in turn doesn’t allow proper interaction with the postgres database … and that also not allowing to get into your WebUI, etc.
If I were to believe this post on askubuntu, then your reboot might have happened right in the middle of a transaction, which in turn blocks the remounting of your shares …
Take a look, but also proceed with caution, as I am not an expert in this area (so I might be sending you down the wrong rabbithole). But maybe the post above rings a bell with our more senior technologists in the community.
For completeness sake, here are a couple of other threads from within RockStor discussing similar issues:
which intersect somewhat with your challenges you’re having.
