Case:
Yuyao Pharmaceutical’s HP server hard disk is bad, HP server, 3 500G SATA enterprise hard disk RAID0 disk arrays, which was originally a RAID0 array built by customers.The customer’s hard disk is also a raid-0 assembly of the three different series of hard disks. The customer’s data is the data of a pharmaceutical retail store in Yuyao.All inventory and sales data of 10 stores and stores.Customers find a data recovery through the Internet.The previous data recovery company opened the market to discover the physical scratching of hard disks and abandoned recovery.Finally, the data recovery center test was introduced at the time of despair.Data recovery detection hard disk is a physical RAID-0 data. If one of the hard disks cannot be restored, the data is also failed.But the database file required by customers.The worst plan is that some data can be compared with existing inventory.
Solution:
By analyzing the RAID disk, block size, or dirty disk and other related parameters of the two disks, the virtual reorganization RAID0 successfully restored all data. The RAID0 uses a typical RAID mode.Reorganize through database fragments.Once again, the nodes on the scratching hard disk are restored and read on the scratching hard disk, and the successful data is perfectly restored to the backup database of March 10, 2012.Engineers suggest: Once the storage device such as server, disk array cabinet has a fan failure warning, it should be replaced in time, otherwise the huge calories at the hard disk may cause damage to the hard disk or crash.
