In RAID5 if two drives had failed, you can do nothing about this.
But if you have Matrix Manager 8.9x, you MUST fallback to 8.8, as 8.9 are dangerous to RAIDs.
I,ve the same problem.
Any Response since 2010?
It is important to mention that is possible to restore raid 1 by setting the disks to non raid and no information will be lost; however, I regret to say that on RAID 5 there is no way to restore the data if the structure fails.
Thanks for your answer.
Even if 4 disk on the 5 have no pb?
Can't I copy the 4 good disk, delete the volume, create another one and recopy data on the new volume? then rebuild the 5th one?
I am afraid to say that it is not possible because when using RAID 5 configuration the data is placed in different locations (unknown for us) so you can try it but most probably it will not work.
It is possible to rebuild the Array when the status is degraded because you know what driver is failing and the Operating System knows that files are missing.
