I have a user experiencing problems with mounting/contacted a database. I work in infrastructure so very very little knowledge on db's -- guess I was first/only port of call, so any advice would be greatly appreciated. I have pasted what he has tried and my extremely basic suggestions :)

Initial error reported:

ORA-00283: recovery session canceled due to errors[oracle@*********** ~]$ sqlplus spsystem/reganam
SQL*Plus: Release 11.2.0.4.0 Production on Thu Jul 4 07:08:41 2019
Copyright (c) 1982, 2013, Oracle. All rights reserved.
ERROR:
ORA-01033: ORACLE initialization or shutdown in progress
Process ID: 0
Session ID: 0 Serial number: 0

Enter user-name:

And when entering as sydba

SQL> select * from all_users;
select * from all_users
 *
ERROR at line 1:
ORA-01219: database not open: queries allowed on fixed tables/views only

Quick search on these errors suggested a recovery of the database was needed and for the user to run the following from the SQL> prompt:

SQL> startup mount
ORACLE Instance started
SQL> recover database
Media recovery complete
SQL> alter database open;
Database altered
SQL> startup mount
ORACLE instance started.

**This was attempted and failed**

There are no disk issues and filesystems are healthy (size & condition) and nothing that I can garner from OS logs or that I can fully understand from trace logs?

    Running commands you don't really understand based on a quick search, or on advice you receive here or elsewhere on the internet, has a fairly good chance of making the situation worse *8-) So be careful... It does appear to be a disk issue though - as it's effectively reporting a bad block. – Alex Poole Jul 11 '19 at 9:34
  • Perhaps that drive has run out of space. – Nick.McDermaid Jul 11 '19 at 11:02
