Need some information on RAID 5,6 or RAID ingeneral. Had a problem this weekend with a RAID 5 implementation on a HP MSA 2012. I had a drive fail and while the system was rebuilding with the global spare another drive failed.
My question is can any RAID set survive this scenerio? I can see where different RAID sets can handle multiple failures but can they recover from multiple failures at the same time or very close to eachother?
I am getting ready to rebuild the failed RAID set and looking for advice, should I use just RAID 5 again or implement RAID 6? RAID 10 is not an option at this time.
