I try to fix a 6tb iscsi volume with VMFS 5
when I first started to look into it the partition table and the area where the magic number is located were completely wiped blank.
I got as far as that the volume is now detected as snapshot but something is still wrong.
Here are some hints in the esxi kernel log:
