Huge Problem- MySql won't start :(
Ok, so we have a database with our CDR records in it, and the server went down, and this is the most recent backup. Apparently the guy who did it copied everything live and so corruption is the possible culprit.
I've already ran myisamchk on the files, and it seemed to do it's thing, but it won't start, here is mysqld.log

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 338332 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
stack_bottom = 0 thread_stack 0x40000
The manual page at xxxxxxxxxxxxxxx contains
information that should help you find out what is causing the crash.
130417 16:38:51 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
I really need to get this database back up, or at the very least extract the information from it.
Please let me know what else i can do.
