Today, I did the dumbest thing I've ever done in my life. I have a PowerEdge server with a PERC 710 RAID controller. I had 4 drives in RAID 5 configuration (1 2.7 TB Virtual Disk) and I wanted to add 4 more drives and expand the RAID (actually I would have settled for a new virtual disk). Anyway, the original virtual disk hosted an ESXi server with some 6 hosts include AD, Exchange, Lync, etc. If you haven't guessed by now, I redid the RAID controller configuration and have now lost everything! I don't have a backup. I have since restored the RAID configuration to the original configuration. I haven't written anything to the disk since that point. Is there any remote chance of recovering the original VMFS volume?
