When I ssh in to my ESXi host and go to /vmfs/volumes/<volume name>, I can see directories for most of my virtual machines. And I can drill into those directories and see the vmdk and other usual content, except in a couple important cases. In those important cases, the directory shows with reasonable perms, time stamp, and size, but listing its content shows nothing. I got here because I was not able to see the virtual machine in vSphere. And this isn't super-surprising because the VM was running at the time we took a power hit. But most of the storage is OK and most of the VMs seem OK. vmkfstools seems only to work at the device level and not on a particular volume directory. voma craps out on the device because it says I have spanned extents. No fsck seems to exist on the host. Anything to try other than going to the SAN backing store and working on it directly (which is mostly a mystery to me and someone else already ran into a dead end there).
