Fail to connect after server crash

While running some programs overnight to populate the database, it
crashed.  I now can not start the database server.  I have a backup of
the database, but to restore I will need to connect...  any help is much
appreciated.

Here is the log from the crash (looks like I ran out of disk space?
there is over 200gb free space...) :
