What not to do when your server on raid 5 system fails

January 4, 2023 No Comments Data Recovery

RAID 5 is a popular storage system that combines multiple disks into a single logical unit and uses striping and parity to provide data redundancy. This means that if one of the disks in the RAID 5 system fails, the system can still function properly. However, if multiple disks fail or the system experiences a catastrophic failure, it can be difficult to recover the data. In this article, we will discuss what not to do when your RAID 5 system fails.

  1. Do not panic: The first thing you should not do when your RAID 5 system fails is panic. While it can be stressful to lose access to important data, panicking will not help the situation. Instead, try to stay calm and approach the problem with a clear head.
  2. Do not attempt to repair the system yourself: If you are not a trained raid data recovery professional, it is not advisable to try to repair the RAID 5 system yourself. Attempting to do so could potentially cause further damage to the system and make it even harder to recover the data.
  3. Do not power off the system: If the RAID 5 system is experiencing a hardware failure, it is important to leave it powered on. Turning the system off could cause further damage and make it more difficult to recover the data.
  4. Do not attempt to recover the data using software: While there are many software programs that claim to be able to recover data from a failed RAID 5 system, it is usually not advisable to use them. These programs can often cause further damage to the system and make it harder to recover the data.
  5. Do not wait too long to seek help: If you are unable to access your data or the RAID 5 system is experiencing a catastrophic failure, it is important to seek help as soon as possible. The longer you wait, the harder it may be to recover the data.

In conclusion, if your RAID 5 system fails, it is important not to panic, attempt to repair the system yourself, power off the system, use data recovery software, or wait too long to seek help. Instead, try to stay calm and seek the assistance of a professional data recovery company as soon as possible to maximize the chances of recovering your data

RAID SYSTEMS
RAID stands for Redundant Array OF Independent Discs, which is a data storage technology that combines multiple physical disk drives into a single logical unit for the purpose of data redundancy or even both.
  TYPES OF RAID SYSTEMS
1) Software RAID: RAID system that doesn’t require a dedicated hardware RAID controller. The RAID compatibility depends on the operating system. It applies whereby there is a single disk with two partitions; one to boot from and the other for data storage.
2) Hardware/Physical RAID: RAID controllers are required in this setup. This controllers support different levels of RAID and also specify the kinds of disks to be used in the array; SSD, SATA OR SAS.
LEVELS OF RAID
RAID 0: Consists of stripping, without mirroring of parity. The capacity of this level of RAID is the sum of all the disks in the set. Failure of one disk in the set causes loss of the entire RAID and the chances of data recovery are minimized.
RAID 1: Consists of data mirroring, without parity or stripping. Data is written identically to two or more drives therefore producing a mirrored set of drives in the set.
RAID 2: Consists of bit-level stripping whereby data is stripped in a way that each sequential bit is on a different drive.
RAID 3: Consists of byte-level stripping whereby data is stripped in a way that each sequential byte is on a different drive.
RAID 4: Consists of block-level stripping with dedicated parity whereby the read/write operations do not spread across all data drives.
RAID 5: Consists of block-level stripping with distributed parity whereby the parity info is distributed among all drives requiring all drives but one to be present to operate. Upon failure of a single drive, subsequent reads can be calculated from the distributed parity such that no data is lost.
RAID 6: Consists of block-level stripping with double distributed parity. This provides fault tolerance of up to two failed drives.
Nested (Hybrid) RAID: Many controllers allow RAID levels to be nested. The elements of RAID may be individual drives or arrays by themselves.

Note: Attempting to recover a RAID without an unexperienced data recovery specialist can put your critical data at further risk. When hardware malfunction is a component of the problem, permanent destruction of data can occur with failed recovery attempts.
