Our Advice in case of RAID Failure
- Do not try to reboot system, as this could cause a serious damage to the array.
- Do not change the order of the drives in an array.
- Turn the whole server/computer and the array off.
- If a drive is making an unusual noise, such as clicking or grinding, turn it off immediately. Running a physically failed drive can cause irreparable damage to the platters.
- Do not run defragment or volume repair utilities on suspected failed drives: Utilities such as chkdsk,scandisk, and fsck are generally not intended for RAID repair. They can make the damage far worse..
- Record the events you observed that led to the failure along with all attempts you have made, if any, to remedy the problem and any consequences you observed.
- Do not swap another disk into the array: It is highly advisable not to perform this operation in any potential data loss scenario.
