3 Raid 5 Failure Causes and Solutions
Raid 5 is one of the ideal raid levels that almost every business prefers for better performance and data redundancy.
Raid 5 provides fault tolerance that protects the raid array from failure due to one hard drive failure and helps the array continue the operations. However, fault tolerance doesn’t make the raid 5 array data loss proof.
Here are the primary and most common raid 5 data loss causes that you should avoid and protect your raid 5 data.
1. More than one disk fails in the array
Provided that raid 5 has fault tolerance and once failure occurs in one drive, other disks in the array will continue to work.
Unfortunately, if the failed drive is not replaced in time, the entire disks in the array will ultimately fail. Fault tolerance doesn’t mean backup.
The sooner you understand it, the better you will protect your raid 5 data.
2. Controller failure in raid 5
A controller plays a vital role in managing all hard drives in the array. Once the raid controller fails, the Raid can suffer parity loss. This can make the array stop working also.
Raid controller problems can be resolved professionally by a raid recovery specialist.
3. Raid rebuild problems
Raid rebuild failure probably occurs after a power outage which can destroy the entire raid array. However, in the raid 5 rebuild failure, it is complex to fix raid 5 because of parity loss. You should leave such a sensitive case on Raid 5 recovery experts only.
Final words
Raid 5 might be a good option for redundancy features, but it is not failure-proof. You should have a data backup offsite or on-site depending on how to recover raid 5 data after raid 5 failure. Raid rebuild failure or controller failure can be sensitive to deal with, and you should contact raid experts to resolve them.
