ASM keep data in disk header - all data has been overwritten by fdisk and in that case it can be very difficult to repair it. Everything should be running until nodes reboot. There is a tool to read and write to ASM headers but I'm not sure if ASM keep all necessary data
in memory and if we can access that to restore disk header.

Drop disk and re-balance looks like only option.
