Corrupt files in log_dir

Dear All,

In our development database, a logfile under log_dir got corrupted. The timestamp on the logfile is set at 20th may, when the system was last stopped.

Now the system is unable to perform crash recovery, because of the corrupt log file.

Is there any way to start the development database bypassing the files in log_dir?

Given below are the logs from db2diag.log:
