I'm running a Ubuntu 12.04 LTS Virtual Machine. Last week, the VM stopped unexpectedly now mysql will not start on the VM. These two events may be related, they may not be.

When I try to connect:

$ mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Then:

$ sudo service mysql start
start: Job failed to start

And

$ dmesg

[ 1838.218400] type=1400 audit(1374633238.253:50): apparmor="STATUS" operation="profile_replace" name="/usr/sbin/mysqld" pid=18473 comm="apparmor_parser"
[ 1838.358656] init: mysql main process (18477) terminated with status 1
[ 1838.358695] init: mysql main process ended, respawning
[ 1839.269303] init: mysql post-start process (18478) terminated with status 1

And

$ service mysql status
mysql stop/waiting

I think this means mysql is crashing when it starts:

$ sudo mysqld start
130723 21:51:24  InnoDB: Assertion failure in thread 3064211200 in file fut0lst.ic line 83
InnoDB: Failing assertion: addr.page == FIL_NULL || addr.boffset >= FIL_PAGE_DATA
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to
InnoDB: http://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html
InnoDB: about forcing recovery.
02:51:24 UTC - mysqld got signal 6 ;

Per the manual, I went to the data directory (/var/lib/mysql) and ran this:

myisamchk --silent --force */*.MYI

Then:

$ sudo mysqld
...
InnoDB: Your database may be corrupt or you may have copied the InnoDB
InnoDB: tablespace but not the InnoDB log files. See
InnoDB: http://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html

Is my database corrupt? What can I do to recover? Re-install mysql? Something less drastic? I'm fine with losing the database, I just want a working system.
