That was my initial deployment concept. Run each Volume Mgr instance in a VM. Mount one 16TB drive into each.

It also turns out that Seaweed has an 8TB limit on volume size, so those nice 16T drives aren't usable properly here.


Turns out the VM aspect isn't important. Can run 4 Volume Mgrs directly on the host OS. Regrettably, this is also incomplete, you need at least one more process, either "Filer" or "S3". (S3 apparently runs a Filer on the inside, but integrated.)

My suspicion right now is that I am doing this Volume Manager thing wrong, that you only want one per machine, and that it can handle multiple disks/folder as volumes. I don't know how you do this, yet.


In order to do anything interesting in terms of data, using S3, you will have to use the "SHELL" process also. This is how you create users (owners) and buckets. I have hunted for separate GUI tools, but haven't been impressed with what I saw; I would like to not have to create my own, but that may end up being what happens.
