      Linux CentOS7 3.10.0-693.17.1.el7.x86_64 #1 SMP Thu Jan 25 20:13:58 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

      Description

      Yesterday my server suddenly alerted. I found that my database is not connected. Go in to check and find out that my database seems to be reset. All databases are lost. The data file and auto.conf are also just generated. Carefully examined the server to eliminate the possibility of hacker attacks. I posted the log of this point. Note that UTC time is not the same as Beijing time.

      2018-03-14T00:03:18.100305Z 0 [ERROR] [FATAL] InnoDB: Native Linux AIO interface. io_submit() call failed when resubmitting a partial I/O request on the file ./ibtmp1.
      2018-03-14 08:03:18 0x7f296ec96700 InnoDB: Assertion failure in thread 139815929079552 in file ut0ut.cc line 917
      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

      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.
      Attempting to collect some information that could help diagnose the problem.
      As this is a crash and something is definitely wrong, the information
      collection process might fail.

      Hope that's ok; if not, decrease some variables in the equation.
