Subject:InnoDB Crash RECOVERY HELP (Urgent)
View as plain text  
Dear all,
our DB server crashed and when I try to start Mysql
/etc/init.d/mysql/start
I get these lins in my error log

060921 13:00:14  mysqld started
060921 13:00:14  InnoDB: Database was not shut down normally!
InnoDB: Starting crash recovery.
InnoDB: Reading tablespace information from the .ibd files...
InnoDB: Restoring possible half-written data pages from the doublewrite
InnoDB: buffer...
060921 13:00:14  InnoDB: Starting log scan based on checkpoint at
InnoDB: log sequence number 3 3546172175.
InnoDB: Error: tried to read 65536 bytes at offset 0 2173440.
InnoDB: Was only able to read 54784.
InnoDB: Fatal error: cannot read from file. OS error number 17.
060921 13:01:24InnoDB: Assertion failure in thread 3086943936 in file
os0file.c line 2107
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/mysql/en/Forcing_recovery.html
InnoDB: about forcing recovery.
mysqld got signal 11;
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.

key_buffer_size=0
read_buffer_size=536866816
max_used_connections=0
max_connections=550
threads_connected=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections =
2094947 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

thd=(nil)
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
Cannot determine thread, fp=0xbffe3d4c, backtrace may not be correct.
Stack range sanity check OK, backtrace follows:
0x814cbfb
0x8d28b8
0x10000
0x8355aed
0x835c659
0x835ce73
0x829ba01
0x81d3af3
0x81c5cb2
0x815028a
0x773e33
0x80e0c71
New value of fp=(nil) failed sanity check, terminating stack trace!
Please read http://dev.mysql.com/doc/mysql/en/Using_stack_trace.html and
follow instructions on how to resolve the stack trace. Resolved
stack trace is much more helpful in diagnosing the problem, so please do
resolve it
The manual page at http://www.mysql.com/doc/en/Crashing.html contains
information that should help you find out what is causing the crash.
060921 13:01:24  mysqld ended

when I add skip-innodb in my.cnf, it startsup but my innodb tables could not
be accessed.

How can I start MySQL server again?
