Case:
Dell PowerEdge R910 server 5 Windows operating system Higgian hard disk composed of a RAID disk alarm. After offline, you have done REBUILD to detect the lag of No. 1., Join No. 4, the difference or test is all wrong, but most of the data is correct
Solution:
1. Full backup of all non -heat -reserve hard disks with good running status to a safe storage with redundant functions, the hard disk that exists in physical problems must be restored according to the corresponding faulty type solution, and the maximum possibility of the fault is maximized.The data of the physical hard disk is also backup to safe storage 2. Analysis of all hard disk mirrors that have been fully backup currently backup to determine the original structural parameters of the fault RAID, and determine the offline situation of each hard disk in the fault raid 3. Analyze the RAID parameters and offline of the analysis.The hard disk situation builds RAID data in only read the environment, and conducts a basic logical verification of the virtual RAID built, and determines the general structure of the file system after correct the structure of the file system.With verification, if the file system in the mirror is still inconsistent, it is fixed according to the solution of the corresponding file system damage, until the data needed by the user needs
