Lost all datafiles in Database Server!
I have a big problem that all of our datafiles, archive files and backup directory was lost. The struture of our database directories is as following:
1)/PROD/oradata: store all datafiles
2)/PROD/oraindex: store all indexfiles
3)/PROD/system: store system tablespace datafiles
4)/PROD/archive: store archive log
5)/PROD/backup: store backup data
The problem is all files of oraindex, system, archive, backup directories were lost. The most of datafiles inside oradata still remain, lost some files and directory inside this directory.
When I checked the Oracle Alert logfile, the duration for the error is very short, it just happened from 15:13:24 to 15:13:27 (just 3 seconds) while all of losted file is around 1TB.
I worry that error is caused by losting matadata because nobody can remove 1TB with just 3 seconds.
Could you please help us to find out the reason
of the error and recomend us how to prevent that problem from happening again.
Thank you very much.

Re: Lost all datafiles in Database Server!
Thank you very much for your help.
The database down right after files were lost.
There is no errors in syslog.log, so that we can say nobody use lvreduce command.
Please check the attachment for the syslog.log and alert log file for more details.
Thanks and Regards,
Tung
