those both need to be flipped. External port first then the internal port in the container.
As for LVM, RAID or any other solution to combine disks. You should avoid all of them. You either create a situation where you lose your entire node when one HDD fails or you’re wasting space for redundancy instead of making money on that space.
Say you have 3 HDDs, you could set up a RAID 5 and be protected against drive failure. You lose 1/3rd of the space. But instead, you could also run 3 nodes, one on each disk. And while you’re not protected against drive failure, the failure of one drive will just take down one node, which actually was able to make money on the 1/3rd of space you would have thrown away with the RAID 5 setup from day one.
