If the machine has data, you must be very careful when operating. The internal samba server cannot be accessed, and there is nothing in/share. No data is found. Later, I checked it carefully and found that the machine had five hard disks, which seemed to be a soft raid. 1. Run the fdisk-l command to view and find /Dev/sde1 1 60801 488384001 fd Linux raid autodete 2. cat/proc/mdstat, md0, and md1 are all inactive. 3. I 've taken it all offline for a long time.

The construction of enterprise-level application systems usually stores systems and data separately, and creates raid. The newly installed centos6.5 requires a data disk to be mounted and can be automatically mounted at system startup. 1.
