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? -- Sincerely, Hadi Rastgou A Google Account is the key that unlocks the world of Google. <a href= "http://www.spreadfirefox.com/?q=affiliates&id=0&t=1"> Get Firefox! </a>
