Honestly, I don't see how LVM can interact with VMware's VMDK... unless one |
31 |
use VMware's thin provisioning over a SAN Storage Thin Provisioning, in |
32 |
which case all hell will break loose once the actual disk size is reached... |
33 |
|
34 |
Stick with VMware Thin Provisioning XOR SAN Storage Thin Provisioning. |
35 |
Never both. |

One thing you have to think about, is whether to implement |
38 |
LVM/partition-less, or LVM/partitions. |
