I had an ESXi 6.5 server on a Dell R520 with 8-disk RAID6 ( 8 x 3TB, 18TB)
As mentioned in several threads here, following a RAID crash and drive rebuild, the only datastore disappeared.

Mounting partition #3 via linux/vmfs-tools was successful, and I've been able to copy some of the smaller VMs to a different ESXi server. However, there is a 17TB VM that I would prefer to be able to run P2V Converter on it ( since it contains a large filesystem that is mostly empty at this time ). It consists of 7 .vmdk files , 5 x 2TiB and 2 x 3TB, and the VM has all the drives combined via LVM into a single large volume group.
The server had been originally installed as a 12TB RAID6 (under ESXi 5.5), but the RAID had been grown twice (I think), to 15TB and then 18TB, and the Datastore had been grown twice as well.
I've been unable to figure out how to mount the Datastore inside ESXi. I tried the GUI, but it insists it has to reformat the volume, so I do not proceed.
Any suggestions for getting the data off? Some way to mount the datastore inside ESXi?
Or perhaps I can loopback mount the .vmdk files (via linux/vmfs-tools), reconstruct the volume group, and mount the oversize ext4 filesystem?
